Installation & Hook-Up

sure you correct the wiring before replacing the fuse with a 2A Slow

Blow, 1/4 x 1 1/4 fuse of the same type for continued protection.

Fault Relay

To provide safe operation (opening the fault string if a fault occurs or

power to the ALEC is lost) the fault relay outputs must be connected

appropriately. The fault relay N/O contact is held energized when the

ALEC has not detected a fault.

The Fault Relay provides one normally open status that is voltage free

and isolated from the ground.

The following diagram is an example of a Normally open Fault relay.

This is an example only it is neither a recommendation nor an

endorsement. You know your application best and can best determine

your own needs for a Fault Relay.

Do not apply power to the ALEC until the Mode switch

is set correctly and all other connections have been made.
