MOUNTING
This section contains instructions for mounting the ML-Drive in the door panel of a
NEMA Industrial Electrical enclosure. The ML-Drive 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-Drive:
1) The NEMA Industrial Electrical Enclosure that will house the ML-Drive 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-Drive and other equipment
to provide for proper heat convection. Placing the ML-Drive too close to
adjacent equipment could cause the interior ambient temperature to exceed
55 degrees C. Spacing requirements depend on air flow, enclosure construc-
tion and applied horsepower.
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-Drive 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-Drive. Tighten the mounting screws until the ML-Drive is
mounted securely in the NEMA Electrical Enclosure. Do not overtighten.
