Voltage Range
The S
S
Lighting Controller is factory-set for use with one of the

following voltage ranges which cannot be changed by the user:
·
230V a.c. (nominal); 180V – 260V a.c. (absolute).
·
115V a.c. (nominal); 90V – 130V a.c. (absolute).
Check that the controller is set for the correct range for the intended power
supply by referring to the serial no./rating plate which is mounted inside
the control connection compartment (behind the right-hand access plate).
WARNING: THE MAINS INPUT MUST BE CONNECTED TO A
SINGLE-PHASE SUPPLY ONLY AND MUST BE EARTHED.
CAUTION: Connecting a supply which exceeds the maximum voltage for the
appropriate input range may cause irreparable damage to the S
Frequency Range
The input supply frequency should be within the range 45 – 65Hz.
Supply Protection
The supply input is protected by the internal 3A MCB. No further
external supply protection is required.
Connecting the Mains Supply
Access to the mains input terminals is gained by removing the access
plate (four-screw fixing).

Suitable Cable
All of the S-COM and S-DIM data highways require a screened twisted
pair, whilst all other connections should use equipment wire. For full
details, refer to the Electrosonic Control Cable Specifications data sheet
(part no. I237GB).
Special S-COM cable is available from Helvar Electrosonic which
comprises the following conductors in an overall sleeve:
·
Twisted pair with screen (for data lines).
·
Two power wires (for S-COM supply).
This is ideally suited for use with the S-COM (external) line, but may also
be used on the other S-COM and S-DIM lines if the two power wires are
cut back.
Configuration Switches
