Removing And Mounting The Covers; Ambient Temperature Control; Protecting Inverter From Foreign Matter During Installation - Omron SYSDRIVE 3G3MV Setup Manual

Design
H Ambient Temperature Control
• To enhance operation reliability, the Inverter should be installed in an environment free from extreme
temperature changes.
• If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner
to maintain the internal air temperature below 50°C.
The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air
temperature as low as possible.
• The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temper-
ature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment
and wires are easily influenced by heat.
H Protecting Inverter from Foreign Matter during Installation
• Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will
be affected, causing the Inverter to overheat.

1-1-2 Removing and Mounting the Covers

To mount the Inverter, it is necessary to remove the front cover, terminal cover (unless
the Inverter is a 200-V model), and the Digital Operator. To wire the Inverter, it is neces-
sary to remove the front cover, terminal cover (unless the Inverter is a 200-V model), and
bottom cover from the Inverter.
Follow the instructions below to remove the covers from the Inverter.
To mount the covers, take the opposite steps.
H Removing the Front Cover
• Loosen the front cover mounting screws with a screwdriver.
• Press the left and right sides of the front cover in the arrow 1 directions and lift the bottom of the cover in
the arrow 2 direction to remove the front cover as shown in the following illustration.
