III. Connect a relay (optional) The relays on the S2 are latching relays. Latching relays require a pulse to physically move the switch from open to closed. Once the switch moves, it stays in that position until a new pulse moves it to the other setting, even if power is removed from the S2. Only a new pulse through the relay can move the switch to a different position. Follow the steps below to connect to the S2 relays. 1. Measure and cut enough 2-conductor or 3-conductor, 1mm 2 cable (relay cable) to go from the S2 terminal block to the terminals of the nearest device connecting to the S2 relay signals. 2. Pull the relay cable through one of the pass-throughs in the cable gland. Leave enough cable on both sides to reach the terminal connections. 3. Strip 50mm of outer insulation from one end of the cable. 4. Strip 7mm of insulation from each conductor. 5. Repeat steps 3-4 for the other end of the cable. 6. Connect the conductors to the appropriate Relay 1 terminals on the S2 terminal block. 7. Connect the other end of the cable conductors to the appropriate devices being connected to the S2 relay signals. 8. Repeat steps 1-7 if making a connection to the second relay (RELAY 2).
