2.1 Site Considerations
When choosing an installation site, check all clearances for the
enclosure, for the attached GPT/MVT, for the optional RTD probe, and
if applicable, for the solar panel. Ensure that you can open the front
cover of the ControlWave GFC Plus (hinged on the left side) for wiring
and service. Make sure the display/keypad is accessible and visible.
See Figure 2-4 for a dimensional drawing of the NEMA 3R enclosure
with an MVT.
The ControlWave GFC Plus is designed to operate in a Class I Division
2, Groups C & D environment with a nonincendive rating (see Appendix
