ALL MOUNTED POWER SUPPLY
Both the U.S. and International models of wall power modules are self-contained
switching power supplies designed to plug into a standard building power receptacle of
appropriate voltage. To supply power to the VWG, you then simply plug the coaxial
connector from the VWG-PS-AC into the coaxial power connector on the VWG base
board.
Power Wiring
Only VWG-PS-DC and VWG-PS-AC power supply
with factory installed ferrite on the power cord can
be used with the VWG. The usage of another non-
approved power supply may void the FCC
compliance of the VWG and wireless controllers.
C o n n e c t p o w e r c o rd a s s h o we d i n to
coaxial connector.
Do not plug the coaxial connector from the power supply into
the VWG until all other mounting and wiring is completed. See
“Power Up and Initial Checkout,” section.
Communications Wiring
Connect communications wiring to the VWG using Net1, Net2 or the RS-485 connection
based on VWG model used and configuration.
Note:
Prior to connecting cables, provide strain relief to prevent damage to the controller.
Ethernet—BACnet™ over IP wiring
Two, female 10/100-Mbit Ethernet connections are provided on the VWG. These are RJ-45
connectors labeled NET2 and NET1. Use a standard Ethernet patch cable for connecting to
a hub or Ethernet switch. An activity LED for each Ethernet port is visible and labeled
“NET2” and “NET 1” on the cover.
Note:
Typically, you
only use NET1
(primary port), unless you have a specific
application for isolating a driver’s network traffic to a separate IP address (and
LAN) using NET2. In all cases, port selection can be changed and is
dependent of configuration made using the VWG configuration tool.
