This document is a guide on the different types, sizes, and lengths of cables that can be used for the IPSUM® System, as well

as network topology requirements and useful tips. This does not replace the requirement of an electrician or over-ride any of

the local country regulations and is provided as a guide only.

The document is split into two section covering the cables used for an IPSUM® installation. The  rst covering Power & Control

(0 - 10 V, 24 V & 230 V) and the second covering networks (TIA/EIA-485 (RS-485) & Ethernet).

At the end of the document are appendixes with cable suggestions and typical installations.

2.1 IPSUM® Main components

2.1.1 IPSUM® System Optimizer/Router

The IPSUM® System Optimizer/Router can both be powered

from either 230 Vac or 24 Vac/dc. The selection is made

using a dip-swich.

When 230 V is used, a phase, neutral and a protective

ground (earth) must be connected. Please follow your

country’s/region’s standard for the wire colours. In the

European Union the phase (L) should be connected to a

brown wire, the neutral (N) to a blue wire and the protective

ground (earth) to the yellow/green wire.

The maximum cable cross sectional area when 230 V

is used is 2.5 mm2 and the recommended minimum is 1.5

mm2. Use cables which are rated for at least 250 V.

The maximum cable cross sectional area when 24 V is

used is 1.5 mm2 and the recommended minimum is 0.5

mm2. Use cables rated for use in low voltage systems.

2.1.2 IPSUM® Connection Unit

The maximum cable cross sectional area when screw termi-

nals are used is 1.5 mm2 and the recommended minimum is

0.5 mm2.

The maximum cable cross sectional area when RJ con-

nectors are used is AWG24 (0.205 mm2) and the recom-

mended minimum is AWG26 (0.128 mm2). The RJ connectors

have two pins for each of the power conductors so the

maximum area can be doubled allowing longer cable lengths

or higher loads.

The RJ45-plug has eight conductors and the RJ12-plug

has six conductors. Use cables rated for use in low voltage

systems.

The communication cables have special requirements, see

the Network section of this guide.

On the following page is a graphic for quick selection of

cable sizes based on cable length, product types, and their

quantities.

2.2 Cable lengths

Devices with Modbus communication

Since these devices are on a stub of the network, the cable

lengths to these are primarily not determined by the power of

the devices but of the maximum allowed stub length of 20 m.

These devices are the Room Controller, EMxx and RWxx,

numbers 6, 7, 8 and 9 in the picture on the following page.

Non communication devices

The cable lengths to these are determined by the power

consumption of the device and the number of devices con-

nected the terminal. These devices are, see the picture on

next page.

2.3 Cable requirements and power consumptions for devices connected to

the IPSUM® Connetcion Unit

The green rows are accessories and are connected to the green area on the Connection Unit.

The purple rows are products and are connected to the purple area on the Connection Unit.

The orange rows are controllers and connected to the orange area on the Connection Unit.

* These are individual limits per device type, the total power (Va) should not exceed 50 Va for all devices

(Which may reduce the individual limits when different device types are connected).

** Not connected at the same time (Either STRA, EMSF or none).

*** Only two of the three can be connected at the same time.

**** Less cables can be used if not all the functionality is required but this is not recommenced as it limits adding functions later.

For details on using less cores please see section 4 of the ”Installation Guide” (Document Number 9402).

2.4 Calculating the minimum cross

sectional area

For trouble-free operation it is important to ensure that the

vol-

tage drop between the connection unit and the device is

kept below the speci ed limits.

The minimum area for the cable is given by the following

formula:

A = 0.0015 x L x P

where

A = Cross sectional area (CSA) mm2

L = Cable length in m

P = Power consumption of the device in VA

The power consumption of the devices is given in the table on

the previous page of this document.

Example 1

A 15 meter cable is required between an IPSUM® connection

unit and an STRZ-70 thermal actuator.

From the table reference, we can  nd that the power con-

sumption of the device is 6 VA.

So the minimum required cable cross sectional area is:

A=0.0015*L*P

0.0015 x 15 x 6 = 0.135 mm2

So a cable with at least that cross sectional area is required.

If two (or more) devices are connected in a daisy-chain then

the  rst cable from the connection box must be sized for

the total power. In theory it may be possible to reduce the

size of the cable for subsequent sections but in general we

do not recommend that, and suggest the same cable is used

throughout.

3.2.2 Optimizer to Router Wiring (Ethernet – Shared Network), Full mode

The Routers can also be connected to the customers existing network (Shared) along with the Optimizer. This removes the need

for a separate network just for the HVAC system (fewer cables, fewer power supplies, e.t.c.). The maximum length between the

LAN (Switch) and the devices is 100 meters. The maximum number of Routers that can be connected to an Optimizer is 30

(Combined on TIA/EIA-485 (RS-485), Ethernet – Private or Ethernet – Shared).

3.3 Network deﬁ nitions and requirements in detail

3.3.1 TIA/EIA-485 (RS-485)

Cabling

The Modbus/RTU and BACnet MS/TP cabling must use

twisted pair conductors and the cable should ful l the EIA-

485 speci cation for 2-wire systems. A single twisted pair

must always be used for the data, and another conductor

must be used for a signal reference ground between de-

vices. Do not use a shield drain wire for the signal reference

grounding.

If RJ45 or RJ12 connectors are used, the maximum wire

gauge is AWG24. If the screw terminals are used, the maximum

cross sectional area of the wire is 1.5 mm2. The area

correlates with a maximum cable length and quality of signal.

Therefore the area should not be less than AWG26/ 0.129 mm2.

Avoid crossing high voltage cables, the cables must be

kept separate from major interference sources such as gen-

erators, relays or frequency transformers. If the installation

is in an environment with lots of interference Fläkt Woods

recommends that the screw terminals are used instead of

the RJ connectors, then a larger cross sectional area can be

used to secure reliable communication.

Shielded cables should be used if the environment has

sources of interference.

TIA/EIA-485 Speciﬁ cation

TIA/EIA-485 is a standard which speci es the physical layer of

the OSI model for the generator and receiver used in a

balanced serial transmission system. EIA-485 is a half-duplex

multi-point communication network, meaning the data can be

transmitted in both directions on a signal carrier, but only in

one direction at a time.

The data is transmitted via two signal lines. The lines are

used for both transmission and reception. Logical stage of

the signal is de ned as a difference of the signal lines. The

differential interpretation combined with a single twisted pair

provides effective protection against interference. Note that

the naming of the lines varies. The signal lines may need to be

swapped around to get the communication working. Incor-

rect polarity cannot harm either device.

Topology

The recommended network structure has one trunk cable

to which devices are connected directly or by short stubs.

The stub is de ned as a distance from a device to the trunk

cable. EIA-485 does not de ne the maximum stub length,

but it re-commends that the stubs should be as short as

possible. A long stub reduces the quality of the signal mainly

by causing unwanted re ections. According to the Modbus

speci cation, a stub must never be longer than 20 m.

The transmission line must be terminated near each of

the two ends of the bus to avoid re ection. IPSUM® System

Optimizer, Router, and Connection Unit all have built-in ter-

mination resistors. The termination can be easily activated

by moving a dip-switch.

Cable Guide

9489 GB 2016.01.08 13 We reserve the right to alter speci cations.

IPSUM®

In compact mode, the IPSUM® System Optimizer is a mas-

ter to the products on the system side. The system network

starts from the Optimizer and from there all Connection Units

must be connected in series. The built-in termination resis-

tor of the Optimizer and the last Connection Unit must be

activated.

In full mode, the IPSUM® System Optimizer is a master

to the Routers and the Routers are masters to the products

on the system side, meaning the Optimizer does not have

direct contact to the components. The Optimizer network

starts from the Optimizer and from there all Routers must be

connected in series. The built-in termination resistor of the

Optimizer and the last Router must be activated. The system

networks start from each Router and from there all Connec-

tion Units must be connected in series. The built-in termina-

tion resistor of each Router and each of the last Connection

Units must be activated.

The network topology must not be a star, a ring, or a

backbone with stars or cluster (See above for example illus-

trations of these topologies). It is dif cult to determine where

two ends of the bus are when these topologies are used,

therefore the bus cannot be properly terminated. A star

structure may also cause harmonic noise to the signal. Any

star, ring, and backbone with stars or cluster must be removed

from the network.

Cable Length

The theoretical maximum length of the cable depends on the

communication speed and the cable properties such as

characteristic impedance and wire gauge. The Modbus

speci cation de nes the maximum length for the cable as

1,000 meters when the wire gauge is suf cient. AWG 24 is

always suf cient for the Modbus data. When the baud rate

is 19,200 or higher, characteristic impedance with a value of

100 Ohms is recommended.

The stubs should be as short as possible to avoid signal

re ection on the line. The maximum stub length depends on

the signal velocity of the cable and the rise time of the driver.

The higher the values are, the shorter the stub lengths allowed.

The maximum stub length in the IPSUM® System is limited

by the Modbus speci cation and should therefore never be

longer than 20 m.

The maximum length also depends on the quality of the

conductors, the environment and how much of the twisted

pair is unwound at each connection point. The actual maxi-

mum length may therefore be shorter than de ned in the

Modbus speci cation. The higher the communication speed

the more sensitive the system is.

According to the Modbus speci cation, Category 5 (Cat5)

or better cables may also be used in TIA/EIA-485 system.

The maximum cable length is then 600 meters. TIA/EIA-485

rated cables should be used over Cat5 cables in particular

when the system has a lot of rooms and branches or when

the environment has sources of interference.

3.3.2 Ethernet (TCP/IP)

Cabling

Both the IPSUM® System Optimizer and IPSUM® System

Routers can be connected to the client network or a private

network using TCP/IP protocol. In this case the cables must

ful l Category 5 as de ned in the EIA-568 standard.

Shielded cables should be used if the environment has

sources of interference.

TIA/EIA-568 Speciﬁ cation

TCP/IP is a packet-based communication protocol for the

Internet. The communication protocol can also be used in

private networks such as intranets. The protocol de nes

how the message is divided into smaller packets and how

the packets are addressed to the right destination.

Cable Length

The maximum length between the devices is 100 meters.
