VWG-40
Viconics Wireless Gateway
Hardware Installation Guide
(Issue Date September 24, 2008 – 028-0179 R8)
Product overview
The VWG-40 and related wireless thermostats are targeted to retrofit applications where the
addition of communicating field bus wiring within the building space is prohibitive. The
Gateway and Communicating Thermostats with wireless field bus encourages the use of
existing wiring utilized by existing electronic thermostat type controls.
The VWG-40 when utilized in conjunction with the VT7xxxXxxxxW series wireless thermostats will offer the integrator
simple BACnet IP or BACnet MS/TP objects to integrate over standard building automation systems using familiar
integration toolsets.
A maximum of 30 wireless thermostats can be wirelessly attached to a single VWG

All VT7000 series wireless thermostats 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 thermostat
product line and associated network access point (VWG-40-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 thermostats may void the FCC compliance of
the VWG and wireless thermostats.
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 thermostats.
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 thermostats.
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.

Material and Tools Required
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 an 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 c areful. They alert readers to situations where the re 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 cha nce that the
reader might do something that can result in personal injur y or equipment damage. Warnings contain an explanation o
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 dama ge.
• 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 (if using the VWG-PS-AC power supply). Disconnect power before installation or servicing to
prevent electrical shock or equipment damage.
• Make all connections in accordance with national and local electrical codes. Use copper conductor s o nl y.
• To reduce the risk of fire or electrical shock, install in a controlled environment relatively free of contam i n an ts .
• This device is only intended for use as a moni toring and cont rol device . To p revent d ata loss o r equipm ent dam age, do
not use it for any other pu rpose.
• All Viconics wireless gateways and related wireless thermostats 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 Precautio ns
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 ele ctricity by touching a k nown,
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.
