Connect each relay to a control device or an alarm device as necessary. Refer to Figure 10 and Table 4 to connect the relays. Refer to Configure the high voltage relays on page 36 to configure the trigger condition for each relay.

Refer to Specifications on page 3 for the relay specifications. The relays are isolated from each other and the low-voltage input/output circuitry.

The largest gauge wire the power and relay plugs are rated for 1.5 mm2 (16 AWG). The relay terminals accept 0.75 to 1.5 mm2 (18 to 16 AWG) wire (as determined by load application). Use wire with an insulation rating of 300 VAC or higher. Insert each wire into the appropriate terminal until the insulation is seated against the connector with no bare wire exposed. Tug gently after insertion to make sure that there is a secure connection. If necessary, remove the connector from the PCBA for easier wiring of the terminals. Flexible wires must have a crimped ferrule or a pin type terminal on the end.

Note: Make sure that all of the cables stay below the cable limit line printed on the PCBA to prevent interferences with the high-voltage barrier.

The current to the relay contacts must be 5 A (resistive only load), 1250 VA 125 W (resistive only load) or less. Make sure to have a second switch available to remove power from the relays locally in case of an emergency or for maintenance.

For AC controllers, use the relays at high voltage. For DC controllers, use the relays at low voltage.

Refer to Specifications on page 3 for the relay specifications. Do not configure a combination of both high and low voltage.

Relay terminal connections to the mains circuit in permanent connection applications must have insulation rated for a minimum of 300 V, 90 °C (194 °F). Terminals connected to the mains circuit with a power cord connection must be double insulated and rated 300 V, 90 °C (194 °F) at both the inner and outer insulation levels.

Note: Put the wires for relays through the strain relief fitting for the high voltage relay. Refer to Figure 6 on page 13.
