● Cover the top of the AC drive with cloth or paper during installation to prevent
foreign objects, such as metal chippings, oil, and water, from entering the AC
drive. Foreign objects may cause malfunction of the AC drive. Remove the cloth or
paper after installation is completed. Failure to comply may degrade ventilation
and result in overtemperature of the AC drive.
● Reserve sufficient clearance for heat dissipation, including heat dissipation of
other equipment in the cabinet. For details, see "Installing one alone" in Clearance
of the MD580 Series Low‑Voltage High‑Performance Engineering AC Drive
Installation Guide.
● Keep the AC drive upright to facilitate upward heat dissipation. To install multiple
AC drives in one cabinet, arrange them side by side. Where up and down
arrangement is required, install an air guide plate in between. For details, see
"Installing one above another" in Clearance of the MD580 Series Low‑Voltage High‑
Performance Engineering AC Drive Installation Guide.
● Use a mounting bracket (if needed) that is flame retardant.
● In environments with metal dust, use an enclosed cabinet that can completely
isolate the AC drive from the metal dust. In this case, ensure the maximum
possible space in the cabinet and install cooling devices outside the cabinet.

● Before installing the AC drive, install the bottom mounting bracket and guide rails
on the cabinet, and prepare fixing beams with mounting holes for retaining the AC
drive. Reserve sufficient clearance in the cabinet for connecting side copper
busbars.
● The guide rails in the cabinet and the four casters of the AC drive cooperate to
help the AC drive move in or out of the cabinet. Align the casters with the guide
rails before a push or pull. For safety, arrange two persons to pull or push the AC
drive together.
● Reserve sufficient clearance for heat dissipation, including heat dissipation of
other equipment in the cabinet.
● To push the AC drive into or pull it out of the cabinet, arrange two persons to work
together. After pushing the AC drive into the cabinet, remove the baffle from the
air outlet of the cabinet to avoid over‑temperature caused by failure to exhaust
hot air.
● Install an insulation barrier at the top of the cabinet to prevent the exhaust air
from flowing back into the cabinet. Provide an air intake vent on the lower part of
the cabinet door.
● The cabinet is 2200 mm x 800 mm x 600 mm (including a ventilation top cover 200
mm in height). The cabinet needs to be installed on a base that is 100 mm in
height.
