3.6.6 Relay Electrical and Power Connections
Relay Board Stack Overview
The S5000 can be purchased with three relays. Two of the relays can be configured for either de-energized (default) or energized and latching or non-latching.
The third relay is a dedicated fault relay. All electrical connections to internal relays can be made directly on the PC board. The board is labeled for Normally
Open (NO) and Normally Closed (NC) de-energized state.
Relay Specifications
Table 8 Relay Specifications
If using AC power, the relay wires should not be run within the same conduit or cable tray as the DC power supplied to theS5000 or the S5000 junction box. A
separate wire entry on the device should be used for AC power connected to the relays. The S5000 is built with an additional wire entry to allow this.
Exceeding the volt-amp rating of the relay can cause damage to the switching contacts.
Relay Connections to Inductive Loads
If connecting the relays to motors, fluorescent lighting, or other inductive loads, it is necessary to suppress any sparks or inductive feedback that may occur at the
relay contact. These effects may render the unit inoperative.
One way to reduce these effects is to install a Quencharc® (P/N 630413) across the load being switched.
