Installation and Wiring Instructions
REMOTE SETBACK CONTROLLER WITH BUILT IN TRANSFORMER
Ref No. 10314230A
Model:- RSC
WITH BUILT IN TRANSFORMER
Maximum load: 220-240V 50Hz ~ 9A and 380-415V 50H 3 ~ 9A
IMPORTANT - READ THESE INSTRUCTIONS FULLY BEFORE COMMENCING INSTALLATION.
1. Ensure that the mains supply voltage, frequency, number of phases and power rating comply with
the details on the rating label. Check that the controller can cope with the load (including starting
current).
2. All wiring must be in accordance with current I.E.E. wiring regulations (BS7671), or appropriate
standards in your country. The equipment should be provided with a local all pole isolator switch
having a contact separation of at least 3mm. We recommend that the wiring to the equipment be
made in conduit for added protection.
3. Ensure safety regulations and practices are adhered to when installing this equipment.
4. The controller must not be used where it is liable to be subjected to water spray from hoses, etc.,
or where the ambient air temperatures may exceed 400C.
5. When the fan motor thermal protector terminals (TK or TP) are brought out externally, they MUST
be connected to the relevant controller terminals.
DESCRIPTION
The RSC is used to change the power supply to fans (e.g. switching between the mains supply and
the speed controller). The selection of power supply can be achieved by any sensors or timers with
voltage free contacts. Connections between the RSC and the sensor are Extra Low Voltage.
MOUNTING
1. If the controller is mounted on metal or other conductive surface; that must be earthed.
2. Securely mount the controller to the surface using appropriate fasteners. Route the supply
and outlet cables through `knock-out' holes in casing.
GENERAL WIRING
WARNING - ISOLATE MAINS SUPPLY BEFORE MAKING CONNECTIONS.
1. All electrical connections should be made by a properly qualified electrician.
2. Wire the supply and outlet cables as shown in the wiring diagrams.
3. After making wiring connections, replace the lid onto the base and ensure the cable glands;
gasket; etc. are securely located.

IF THE CONTACTS OF THE SELECTOR SWITCH (OR SENSOR) ARE OPENED THE SUPPLY INTO INPUT 1 WILL
BE CONNECTED TO THE OUTPUT AND VICE-VERSA.
NOTE: THE SPEED CONTROLLERS MUST BE PRESET AT THE REQUIRED SPEED AND POWERED UP BEFORE
THE RSC SWITCH OVER, OTHERWISE A FAULT CONDITION WILL RESULT.
EARTHING OF THE FAN MUST BE PROVIDED SEPARATELY IF REQUIRED.
