DEVICES TO THE TRANSFORMER USED FOR
THE POWER/COMM BOARD!
Note:
Diagram Shown Is For Wiring Of
Power/Comm Board When Used
For Connecting Local Loop Devices
Such As VAV/Zone Controllers,
System Manager(s) and Other
Power/Comm Boards . See Page 2
Of This Drawing For Wiring When
Power/Comm Board Is Used For
Connection Of MiniLink Polling
Devices On The Network Loop.
CAUTION!
No Can Be
Connected To The Same
Power/Comm Board(s) That
Are Used To Supply Power
