Orion System VCM-X E-BUS Component - Manual (Page 84)

VCM-X Component & Systems Wiring 84
Communication Devices
Notes:
1.) All wiring to be in accordance with local and national electrical codes
and specifications.
2.) All modular power/comm cables are to be WattMaster part number
PCC-xx or PCCE-xx cables. All other communication wiring to be 2
conductor twisted pair with shield (Belden #82760 or equivalent).
Comm/Power Cable Power/Comm
Board Used For Connecting MiniLink PDs Or Previous MiniLink
PD On Network Loop. If This Is The First Power/Comm Board
On The Network Loop, This Power/Comm Cable Connection Is
Not Required. Instead Use The 3 Pole Terminal Block
Communication Connection As Shown Below And Connect
To The CommLink. See Note 2.
From Other
Connect Power/Comm Cables To Power/Comm
Or MiniLink PDs On The Network Loop Only.
Other Distribution Board
Use To Connect CommLink When
This Is the First Power/Comm Board
On The Network Loop. Otherwise No
Connection Is Required. See Note 2.

WARNING!
DO NOT GROUND THE 24V TRANSFORMER
THAT IS TO BE USED WITH THE POWER/COMM
BOARDS. GROUNDING OF THE TRANSFORMER
WILL DAMAGE THE POWER/COMM BOARD
AND ALL BOARDS CONNECTED TO IT. A
SEPARATE TRANSFORMER MUST BE USED
FOR EACH POWER/COMM BOARD. NO
EXCEPTIONS. DO NOT CONNECT ANY OTHER
DEVICES TO THE TRANSFORMER USED FOR
THE POWER/COMM BOARD!
CAUTION!
No Local Loop Devices
(Modular VAV/Zone
Controllers, System
Manager(s) Etc.) Can Be
Connected To The Same
Power/Comm Board(s) That
Are Used To Supply Power
And Communications For
MinLink PDs On The
Network Loop.
