OUNTING
Mount the VWG in a location that allows clearance for wiring, servicing, and antenna
removal.
Environmental Requirements
Note the following requirements for the VWG mounting location:
This product is intended for indoor use only. Do not expose the unit to ambient
conditions outside of the range of 0ºC (32
º
F) to 50
º
C (122
º
F) and relative humidity
outside the range 5% to 95% non-condensing (pollution degree 1).
If mounting inside an enclosure, that enclosure should be designed to keep the
unit within its required operating range considering 20-watt dissipation by the
controller. This is especially important if the controller is mounted inside an
enclosure with other heat producing equipment.
Do not mount the unit:
– In an area where excessive moisture, corrosive fumes, or explosive vapors
are present.
–
Where vibration or shock is likely to occur.
– In a location
subject to electrical noise
. This includes the proximity of
large electrical contractors, electrical machinery, welding equipment, and
spark igniters.
Physical Mounting
The following information applies about physically mounting the unit.
You can mount the VWG in any orientation. It is not necessary to remove the

molded DIN rail slot and locking clip.
If DIN rail mounting is impractical, you can use screws in mounting tabs on the
VWG
