See figure above to locate connectors and other components on the
VWG controller. Make connections to the VWG in the following
order.
1. Connect earth-grounding wire with spade connector from the earth ground lug on
the VWG. See “Grounding” for details.
2. Prepare power wiring (leave the unit powered off). See “Power Wiring” for details.
3. Connect communications wiring. See “Communications Wiring,” page 14 for ports
available on the VWG base unit. For ports on any installed option board (LON, RS-485,
modem) see the specific mounting and wiring guide for any additional details.
4. Connect the backup battery to the VWG battery connector, and apply power to the
unit. See “Power Up and Initial Checkout,” page 17.
Grounding
Use an earth ground spade lug (0.187") on the base of the VWG for connection to earth
ground. For maximum protection from electrostatic discharge or other forms of EMI, you
should connect this to earth ground using a #16 AWG or larger wire. Keep this wire as
short as possible.
If desired, you can use the wall mount VWG-PS-AC 120 VAC power supply in your office
(when initially commissioning)
