Cable Entries

The control unit case back provides several cable entries. It is designed to

stand away from the wall to leave space for the cables.

Mains Connection

Connect the control unit to a suitable supply using a double pole disconnect

device in accordance with EN60950-1:2001 Clause 3.4.3. Connect the supply

to the control unit using the 3-way terminal block located on the case back.

Secure the cable to the case anchor point using the cable tie provided.

2. All electrical connections should be carried out by a qualified

electrician and must comply with national regulations (for example, with

the current IEE Wiring Regulations in the UK: 16th Edition, Appendix 5 –
