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.

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.
