When routing cables, all applicable national regulations must be complied with.
The MotorController is supplied with a 6' 6 ¾'' cable with US plug (type B).
6.2
Connecting cables in the MotorController
Cables are to be connected in accordance with the chapter "Connection plan for WCC 106", the short chapters and other relevant
paragraphs in these guidelines.
Please ensure that connections are correctly executed - incorrect connection can lead to functional failure in the MotorController or
external products.
The installation must at all times adhere to the applicable regulations, standards and guidelines.
6.3
Connecting protective earth and 120V AC
WCC 106 is factory-fitted with a power supply cable with a 120V US plug with earth wire (type B).
6.4
Installation of comfort keypad
Any comfort keypad should be mounted in a visible position and within easy reach.
6.5
Assembly instructions
Always have assembly, installation, repair and maintenance of ventilation systems carried out by qualified personnel
trained for this purpose.
Rules to be adhered to for setting up and installation
National regulation and guidelines have to be adhered to when planning the use of a ventilation system and its set-up and
Installation.
Accident prevention regulations Adhere to the general accident prevention regulations (APR), the APR for power operated
windows and doors, and the installation rules in your country.
Caution:
If internal coverings are removed the live current parts are exposed.
Guidelines for mounting / installation
•
the MotorController should be mounted on the wall in such a way that there is free access for service inspections.
•
adhere to the installation instructions and your local energy providers.
•
select the place of installation such that free access is guaranteed for maintenance purposes.
•
select cables according to regulations in this instruction - take the calculation of the actuators supply cable lengths into account
when laying the cables.
•
connect the cables in accordance with the drawings provided by the manufacturer.
•
route the cables in the building according to the regulations in this instruction.
•
check all system functions.

Cables should be routed in compliance with applicable regulations.
7.1
Max. cable length
The maximum permitted cable lengths from the MotorController to the actuators, taking into account the cable cross-section, are
shown in the following table.
7.1.1 Formula for calculating max. actuator cable length
Max. cable length = permitted voltage drop 2V (UL) x copper's conductivity (56) x cable cross-section in mm
For ±24V standard actuators, the cable cross-section may not be less than AWG 18 (0.82 mm
above formula.
Maximum actuator cable length: Always measured from the MotorController to the last junction box + actuator cable
Permissible max. voltage drop in the line: 2 Volt
Total actuator current: The sum of all the connected actuators max. current consumption per motor line
Note: do not use the PE wire / green/yellow wire in the actuator cable!
