NOTE
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.
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.
