Hot Tip!
The Energize State is different than the normal state of the physical contact closure position of each relay, which is
determined by circuit board jumpers. This gives you the added benefit of being able to monitor the wire. In the
event of a power failure, the relay would de-energize back to it's normal physical contact closure set by the circuit
board jumper for that relay. Check your jumper settings and relay connections before setting to Normal or
Inverted.
