The relays have one set of voltage-free contacts (see note below) connected to one pair of
terminals via a header. The two terminals are configured for normally closed or normally
open by positioning a jumper on the header.

• The common contact of each relay has a transient suppressor to earth, and must not be
used to switch voltages greater than its rating.
• The common contact is protected with a 3A fuse.
• For default configuration the relays are normally de-energised and energise on
Fault/Isolate/Alarm.
• The corresponding LED illuminates when the relay is energized.
• The relays may be configured under custom control to operate other than default.
If relay RL3 is configured for operation other than Fault (Trouble), jumper P3 on the SPS
must be shifted to positions 1-2 (top).
