UL Listings require NEC Class I and
Class II wiring be kept separate from
each other. Use separate conduit and
cable tie bars inside the enclosure (see
Figure 1) to separate Class I DO wires
from all other Class II wiring.
Mounting on a Surface
For energy management applications only
CAUTION:
Do not install the MEC on a vibrating surface
(for example, an air handler or ductwork).
1. Align the MEC on the mounting surface.
NOTE: The MEC must be positioned to provide
a 3-inch minimum clearance on both
the left and right sides for wires to ports
and connectors.
2. Using the mounting ears on the back of the
controller as a template, mark the position of the
four mounting holes on the surface.
3. Drill the four mounting holes, or start the screws
into the marked template holes.
4. Secure the controller using the appropriate
mounting hardware for the surface.
5. Terminate wires to both the power connector
and the appropriate point connectors.
For more information, see the APOGEE Wiring
Guidelines for Field Panels and Equipment
Controllers (125-3002).
The installation is now complete.
NOTE: If the optional HOAs are immediately
required for equipment control, continue with
the section Using the HOAs Before Start-up.
Mounting in an MEC Enclosure
Required for smoke control applications
WARNING:
Turn off AC power to the MEC enclosure
at the circuit breaker panel.
Siemens Building Technologies, Inc.
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
CAUTION:
Do not install the MEC on a vibrating
surface (for example, an air handler or
ductwork).
NOTE:
For smoke control applications over
Ethernet, Ethernet capable MECs must
be connected to the Ethernet ALN or
BACnet/IP ALN through an Ethernet
switch UL Listed for Fire Signaling. The
panel and the switch must be installed in
the same room.
1.
Carefully align the MEC on the perforated
backplane of the enclosure (Figure 1).
NOTE:
Mount L model MECs in the upper
left-hand corner of the enclosure. This
allows better access to the ports.
2. Using the rear of the controller as a template,
mark the position of the four mounting holes.
3. Start the screws (provided with the enclosure) in
the perforated backplane.
4. Place the MEC on the backplane of the
enclosure so that the mounting ears rest on the
screws and tighten the four screws.
5. Terminate wires to both the power connector
and the appropriate point connectors.
For more information, see the APOGEE Wiring
Guidelines for Field Panels and Equipment
Controllers (125-3002).
The installation is now complete.
NOTE: If the optional HOAs are immediately
required for equipment control, continue with
the section Using the HOAs Before Start-up.
