Electronic controls are static sensitive devices. Discharge yourself properly before
manipulation and installing the Viconics wireless gateway.
All Viconics wireless gateways and related wireless controllers are to be used only as
operating controls. Whenever a control failure could lead to personal injury and or loss of
property, it becomes the responsibility of the user to add safety devices and or alarm
system to protect against such catastrophic failures.
All VT7000 series wireless controllers and associated VWG (Viconics Wireless Gateway)
have been rigorously tested to ensure reliable operation in most building applications using
the latest 2.4 Zigbee™ technologies. Viconics cannot guarantee against potential network
interference should additional wireless systems be deployed sharing close proximity.
Best practices covered in this manual and all related Viconics VWG documents should be
considered as a guide to apply Viconics Wireless Network devices only. The instructions
included in this manual are based upon Viconics in house testing and should be referred to
as a guide only.
Viconics Inc. may not be held liable for continued reliable, or robust operation of any and
all wireless based devices. Although Viconics has taken many precautions in assuring the
robustness of the VT7000 series wireless controller product line and associated network
access point (VWG-50-XXXX-1000) Please note; future application of additional wireless
devices utilizing the same or similar channels and / or frequencies may degrade
performance of overall system and / or reliability.
Non-approved modifications or changes made to the VWG or wireless controllers may void
the FCC compliance of the VWG and wireless controllers.
2 | VWG-50-Installation Manual
Ferrites supplied with the power supply and VWG MUST be installed according to
instructions. Failure to do so may void the FCC compliance of the VWG and wireless
controllers.
Only VWG-PS-DC and VWG-PS-AC power supply 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.
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS
SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT
CAUSE HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY
INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE
UNDESIRED OPERATION.

OVERVIEW
This document covers the mounting and wiring of the Viconics VWG-50 series product. It
assumes that you are an engineer, technician, or service person who is performing control
system installation. Instructions in this document apply to the following products:
Note: Not covered in this document is the configuration appliance software required for
fully setup the gateway. This includes setting host IP address, passwords, database, and
other controller and network utilities. Refer to the document LIT-VWG-50-SETUP-Exx for
more information.

Material and Tools Required
f
r
The following tools and supplies may be required for installation:
DIN rail, type NS35/7.5 (35mm x 7.5mm), recommended for panel mount installation.
Length of DIN rail should be minimum 6.5 “(165 mm).
If using a VWG-PS-DC power supply, use UL listed, Class 2, 24VAC transformer,
supplying a minimum of 5VA to the VWG. Note that the VWG-PS-DC power supply
provides isolation — a dedicated transformer is not required.
Suitable screws and screwdriver for mounting DIN rail, or if DIN rail not used, for
mounting bases of VWG controller and VWG-PS-DC power supply (if used).
PRECAUTIONS
This document uses the following warning and caution conventions:
Cautions remind the reader to be careful. They alert readers to situations
where there is a chance that the reader might perform an action that cannot be
undone, might receive unexpected results, or might lose data. Cautions contain
an explanation of why the action is potentially problematic.
Warnings alert the reader to proceed with extreme care. They alert readers to
situations where there is a chance that the reader might do something that can
result in personal injury or equipment damage. Warnings contain an
explanation of why the action is potentially dangerous.
Safety Precautions
The following items are warnings of a general nature relating to the installation
and start-up of the VWG controller. Be sure to heed these warnings to prevent
personal injury or equipment damage
.
Depending on power module used, the circuit powering the VWG is 24VAC at
50/60 Hz (if using the VWG-PS-DC power supply or 120 VAC at 50/60 Hz (i
using the VWG-PS-AC power supply). Disconnect power before installation o
servicing to prevent electrical shock or equipment damage.
Make all connections in accordance with national and local electrical
codes. Use copper conductors only.
To reduce the risk of fire or electrical shock, install in a controlled
environment relatively free of contaminants.
This device is only intended for use as a monitoring and control device. To
prevent data loss or equipment damage, do not use it for any other
purpose.
All Viconics wireless gateways and related wireless controllers are to be used
only as operating controls. Whenever a control failure could lead to personal
injury and or loss of property, it becomes the responsibility of the user to add
safety devices and or alarm system to protect against such catastrophic

failures.
Static Discharge Precautions
Static charges produce voltages high enough to damage electronic components.
The microprocessors and associated circuitry within a VWG controller are sensitive
to static discharge. Follow these precautions when installing, servicing, or operating
the system:
Work in a static-free area.
Discharge any static electricity you may have accumulated.
Discharge static electricity by touching a known, securely grounded
object.
Do not handle the printed circuit board (PCB) without proper protection
against static discharge. Use a wrist strap when handling PCBs. The wrist
strap clamp must be secured to earth ground.
