NOTE NC and NO designations on MOB AUX contacts are defined with breaker in OFF (open) position.
NOTE If MOB contacts have pigtail leads, use the same wire gauge to connect to the UPS and use the correct crimp connections for the wire gauge.
NOTE External CAN connections between UPS cabinets require shielded twisted-pair wire.
NOTE Use twisted-pair wiring between the UPS and MOB AUX contacts.
NOTE Always confirm contact operation prior to wiring.
