1.2 Introduction

Congratulations on your excellent choice of purchasing a CCU5000!

In order to realize the full benefit from this product it is important that it is installed, commissioned and

operated correctly. Before installation or using the fan, this manual should be studied carefully. It is also

recommended that it is kept safely for future reference. The manual is intended as a reference for

installation, commissioning and day-to-day operation of the Munters Controllers.

1 Safety aspects

1.1 Grounding

• Always connect temperature and sensor shields to earth ground. Avoid mixing high voltage

wiring with sensor and low voltage wiring.

• Keep the controller as far as possible from heavy contactor boxes and other sources of

electrical interference.

• Do not connect communication wire shields, which go from one house to another at both ends.

Connect them at one end only. Connection at both ends can cause ground loop currents to

flow, which reduce reliability.

• The COM connection for communications is not the shield wire. The COM, RX and TX wires

must connect to each other at all controllers.

1.2 13BFiltering

• If this installation includes a power inverter to drive variable speed fans, install an EMI filter in

front of the inverter, according to the specifications provided by the inverter manufacturer. Refer

to the inverter documentation.

1.3 14BChecking the battery level

• Check the battery once a year. The output must be 2.7 volts (minimum). Authorized personnel

only must replace the battery if the output is below the minimum required level or every five

years.

2 Before using

The following section provides an introduction to the CCU5000 Farm Climate Controller units.

The CCU5000 controller provides a comprehensive solution for growers seeking a low cost solution

without sacrificing quality. CCU5000 enables control over the temperature and humidity in buildings

using intelligent, user-friendly climate control software. The CCU5000 comes in three models:

Figure 8: RS-232 Communication Wiring Diagram

Figure 9: RS-485 Communication Wiring Diagram

3.1 Connection the mains voltage

The input power of the controller should be connected to one or a few circuit breakers in the electrical

enclose (fuse box).

• Single wire supply is recommended for applications in which the controller's outputs are

connected to low power contactors. In this case one 18 AWG cable should be used for the

Phase and for the Neutral.

• Multi wire supply is recommended for high power applications in which the outputs supply up

to 5Amp each. In this case a separate 18AWG wires should be connected from each circuit

breaker in the electrical enclose (fuse box) to each output, and to the variable speed fan. All

the wires (from the separate circuit breakers) are from the same single phase.

WARNING!

Multi wire supply! Up to nine independent mains input may present in CCU5000. Be

sure that all appropriate circuit breakers are in position OFF before servicing.

3.2 Electrical grounding for controllers

Electrical equipment can be destroyed or slowly damaged by voltage spikes, lightning hits, etc. Proper

electrical grounding in combination with the CCU5000 internal protections is essential to protect the

system, reduce the risk of damage and prolong its lifetime. Correct selection and installation of equipment

will protect your system and reduce the risk of human injury.

Proper grounding provides an easy path for electrical current to return to its source. A grounding system

should tie all non-current carrying conductors to earth ground (0 volts). The grounding system should

present a minimum resistance to current flow. Make sure all items used are in proper condition; for

example, a corroded wire clamp attaching a ground wire to a ground rod might add 100 ohms or more

resistance to a system. Less than 5 ohm will be considered a good ground.

3.2.1 Ground rods

Ground rods are used to efficiently connect the system to earth where current may be dissipated in the

soil.

• Material: Ground rods should be copper clad or galvanized steel.

• Diameter: Minimum 5/8”, preferably 3/4”. Generally the larger the rod diameter, the lower its

resistance to current flow.

• Length: Minimum 2.5 meters (8 feet), preferably 3-meter (10-foot). A longer ground rod will

reach a soil with higher moisture content. Moist soil carries current much better than drier soil.

• Single grounding: It is important that there is only one grounding location where a rod or series

of rods are connected to each other using a ground wire.

• Independent ground rods will increase the risk of current, from a lightning strike for example,

being dissipated through one rod and reentering the system through an adjacent rod.

• Location: Close to the main circuit breaker panel and in moist soil. For example in an area that

is usually wet from a drip or a low spot where water drains. Make sure the area is well

protected from damage by lawnmowers, tractors, etc.

• Rod installation: Drive the rod into the earth until about 10 cm (4 inches) is left above grade. If

it is impossible to drive the rod to the proper depth, it is acceptable to lay the rod horizontally,

80 cm (2.5 feet) below grade.

• In case the rod is exposed to damage, for example by lawnmowers or tractors, it can be

installed in a hole, about 20 cm (8 inches) deep so that the rod is about 10 cm under grade

and 10 cm above hole level.

The National Electric Code (NEC) mandates two ground rods unless you can show less

than 10 ohms resistance with one rod.

3.2.2 Ground wire

The ground wire is a large copper wire that connects the main circuit breaker panel to the ground rod.

• Material: Ground rods should be copper clad or galvanized steel.

• Diameter: Typically, 16 mm (6-gauge) copper wire is sufficient. If the wire run is greater than

20 feet, 20 mm (4-gauge) wire should be used.

• Length: Minimum 2.5 meters (8 feet), preferably 3-meter (10-foot). A longer ground rod will

reach a soil with higher moisture content. Moist soil carries current much better than drier soil.

The ground wire should be protected from damage by lawnmowers, tractors, etc. It should be buried

minimum 15 cm (6 inches) underground for protection and enter the house as soon as possible. It is

important that the wire not be cut; it should remain continuous.

3.2.3 34BGround clamps

Ground wires should not be merely wrapped around a ground rod. Ground clamps are used to attach a

ground wire to a ground rod. The most common clamp is an acorn clamp. Make sure the ground clamps

you select are rated for outdoor use. Do not use pipe clamps rated for inside water lines or hose clamps

to attach the ground wire.

Figure 10: Ground connection

3.2.4 35BWhat should be grounded?

Any equipment that is or could become energized, even accidentally, should be grounded. Current from

lightning strikes objects in a random fashion. Accounts of lightning strikes reveal scenarios most of us

could not predict.

Electric circuits should be wired with a 3-wire conductor consisting of hot, neutral and grounding wires.

The grounding wire should be attached cleanly and securely to devices or systems to be grounded. The

other end of the grounding wire should be attached to the ground bus on the main panel.
