A Standard Relay's coil is supplied 24 VDC from the Power Center PCB via one of the two driver chips.
When 24 VDC is received by the relay's coil wires, it closes the contacts that complete the circuit to turn on the
equipment (i.e., power supplied to Line 1 goes out Load 1 to the equipment).
Standard Relays may be wired to activate a 110 VAC circuit (e.g., Line 1/Load 1) or a 220 VAC circuit
(e.g., Line 1/Load 1 and Line 2/Load 2).
NOTE: If a relay's coil wires are shorted, or an AC relay coil is plugged into a relay socket, when that circuit is
activated, it will damage one of the two relay Driver Chips (Part No. 3814) on the Power Center PCB. (These
chips can be replaced/see Page 4).
