MOUNTING
This section contains instructions for mounting the ML–Trim in the door panel of a
NEMA Industrial Electrical enclosure. The ML–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 ML–Trim:
1) The NEMA Industrial Electrical Enclosure that will house the ML–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 ML–Trim and other equipment
to provide for proper heat convection. Placing the ML–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 ML–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 ML–Trim. Tighten the mounting screws until the ML–Trim is
mounted securely in the NEMA Electrical Enclosure. Do not overtighten.
