The relay communication card contains six programmable dry contact outputs and two programmable dry inputs and is standard on the MGE Galaxy 4000. The inputs and outputs are factory programmed according to functions listed in table below.

Inputs	Factory Settings	Options (available on both contacts)

1.A	UPS ON	•	Room temperature fault
1.B	UPS OFF	•	Transfer to bypass disabled
		• Transfer to bypass disabled if bypass AC source out of
			tolerance
		• Desynchronize UPS from bypass AC source


Outputs	Factory Settings	Options (available on all contacts)

1.1	General alarm	•	Overload
1.2	Battery fault	•	PFC Fault
1.3	Load on UPS	•	Inverter fault
1.4	Load on automatic	•	Charger fault
	bypass	•	Automatic bypass fault
1.5	Load on battery power	•	Automatic bypass fault
1.5	Load on battery power	•	Bypass AC source out of tolerance

1.6	Low battery warning
1.6	Low battery warning	•	Battery-temperature fault
		•	Battery-temperature fault
		• Emergency power off activated
		• Battery circuit breaker(s) open
		• Phase-sequence fault on normal or bypass
		•	AC source
		•	Blown fuse(s)
		• Transfer to bypass AC source disabled
		• Operation in ECO mode
		• UPS on bypass AC source

The output contacts numbers for a second relay board installed will be 2.1 to 2.6. Contacts are of the NO (normally open) type. For dry contacts setting see “MGE Galaxy 4000 40–75 kVA 208 V Operation Manual — User Configuration — Settings Screen“.

Caution: Isolate and lock-out all power sources for this card before making connections. Never connect ELSV (extra low safety voltage) and non-ELSV circuits to the different outputs of the same card.
