MOUNTING
This section contains instructions for mounting the MLP–Trim in the door panel of a
NEMA Industrial Electrical enclosure. The MLP–Trim is packaged in a compact 1/4 DIN
Vertical Instrument Enclosure that mounts easily in the door of your Industrial Electrical
Enclosure. The Electrical Enclosure must have an IP54 rating or higher to comply with
CE installations.
To mount the MLP–Trim:
1) The NEMA Industrial Electrical Enclosure that will house the MLP–Trim must
conform to the following environmental conditions:
Temperature: 0 - 55 degrees C
(Internal NEMA enclosure temperature)
Humidity: 0 - 95% RH non-condensing
Environment: Pollution degree 2 macro - environment
Altitude: To 3300 feet (1000 meters)
NOTE: Allow adequate spacing between the MLP–Trim and other equip-
ment to provide for proper heat convection. Placing the MLP–Trim too close
to adjacent equipment could cause the interior ambient temperature to
exceed 55 degrees C. Spacing requirements depend on air flow and
enclosure construction.
2) The dimensions for the door panel cutout are 3.65"+ .03" x 3.65 +.03"
(see Figure 2-1). Allow two inches of clearance on all sides of the cutout for
mounting clamp attachments, wire routing and heat convection.
3) Insert the MLP–Trim through the door panel cutout until the gasket and bezel
are flush with the door panel (see Figure 2-1).
4) Slide the mounting clamps into the slots that are located on the top and
bottom of the MLP–Trim. Tighten the mounting screws until the MLP–Trim is
mounted securely in the NEMA Electrical Enclosure. Do not overtighten.
