Making BMS/BAS remote connections for analog and binary (on/off) signals

 

A terminal strip for the remote connection is located behind the hinged control panel at the top of the cabinet and is

 

accessed by removing the bottom cover and then removing the screws at the top of the hinged cover.

 

Important: Do not use single strand bell wire for remote field connections to terminals R1-R2 and C1-C2. Use only

 

multi-strand copper wire. See table below for wire length and gauge:

WARNING: Turn off all electrical service to the appliance when accessing the remote connections located inside the control cabinet. These terminals are High Voltage. If the electrical service is not turned off and these terminals are touched, a dangerous shock causing personal injury or loss of life could occur. Close and fasten the control cabinet cover before restoring electrical service to the appliance.
