Installation
There are three options for installation:
For energy management only, you may mount
the MEC on a surface.
For smoke control applications, mount the MEC
inside an MEC enclosure.
For any application requiring a secure
enclosure, mount the MEC inside a listed
enclosure along with the matching Service Box
and Sidewall Kit, if needed.
CE Compliance Requirements
For installations requiring CE compliance, the MEC
must be installed inside a metal enclosure rated at
IP20 minimum.
See APOGEE Wiring Guidelines for Field Panels
and Equipment Controllers (125-3002) for CE
compliance wiring requirements.
