Mounting the Panel-Mounted GridMaster
Controller Inside the Enclosure
Panel-mounted GridMaster controllers can be installed in
a wide-variety of enclosures. When the associated IED is
provided by S&C Electric Company, the controller may be
factory-installed inside the gear’s low-voltage enclosure.
The panel-mounted GridMaster controller is 14 inches
(356 mm) high, 9.25 inches (235 mm) wide, and 3.82 inches
(97 mm) deep, flange mounted with
3/8
-inch (9.5-mm)
diameter mounting holes. The microgrid controller should
be mounted in “open-construction” style so it may be easily
connected to and serviced without requiring removal of
the controller or surrounding equipment. The GridMaster
controller should be mounted in an appropriate NEMA
enclosure (or equivalent) for protection from weather, dust,
and unintentional intrusion. When mounting the control-
ler on a swing-out panel, make sure any communications
cables are trained and/or harnessed in such a way move-
ment of the panel will not loosen the connections.
To mount the GridMaster controller to the enclosure:
STEP 1.
Tap four holes at the positions shown in Figure
2 on an interior panel of the NEMA enclosure.
The mounting holes have a
3/8
-inch (9.5-mm)
diameter.
STEP 2.
Use a mounting screw appropriately sized for a
3/8
-inch (9.5-mm) hole and a flat washer to secure
the controller inside the enclosure. When
considering placement, make sure there is
enough room to allow for the cables to protrude
from the face of the controller.
