WSHP-X Module
Technical Guide 4
Installation & Wiring
Power Supply
The WSHP-X Module requires a 24 VAC power connection with an
appropriate VA rating.
If you will be connecting the WSHP-X Module to a VCM-X WSHP
Series Controller or SA Series Controller, one of the most important
checks to make before powering up the system for the fi rst time is to
make sure that the Controller is confi gured properly for your applica-
tion. Refer to the VCM-X Controller Technical Guide, VCM-X Modular
E-BUS Controller Technical Guide, SA Controller Technical Guide, or
SA E-BUS Controller Technical Guide for more information.
WARNING: Observe polarity! All boards must be wired
GND-to-GND and 24 VAC-to-VAC. Failure to
observe polarity could result in damage to the
boards.
Environmental Requirements
The WSHP-X Module needs to be installed in an environment that can
maintain a temperature range between -30°F and 150°F and not exceed
90% RH levels (non-condensing).
Mounting
The WSHP-X Module is housed in a plastic enclosure. It is designed to
be mounted by using the 3 mounting holes in the enclosure base. It is
important to mount the module in a location that is free from extreme
high or low temperatures, moisture, dust, and dirt. Be careful not to
damage the electronic components when mounting the module. See
Figure 2 for Module dimensions (in inches).
