External parallel pull chain connections between the UPS and MOB Aux contacts require
twisted pair wire.
If MOB contacts have pigtail leads, use the same wire gauge to connect to UPS and use
the correct crimp connections for the wire gauge.
NC and NO designations on MOB AUX contacts are defined with breaker in OFF (open)
position.
Always confirm contact operation prior to wiring.
Any pair of unused building alarm terminals may be used for the MOB Aux 1
connections.
