Installation
Do not turn on the
AC Supply
or the control power
until all wiring work is completed.
When installing
drives
,
maintain
required clearances for
protective enclosures and control panels for heat dissipation
and air flow.
- Install all
drives
vertically. Use M5 screws at two locations to mount 50 W to 750 W

Specifications:
Drive
Dimensions
- If you are mounting the
drive
into an enclosure such as protective casing, use a fan or air conditioner
so that the ambient temperature inside will not exceed 5
0
°C.
- The temperature of the heat sink at its surface may become 30 °C (or more) higher than the ambient temperature.
- Use heat resistant wiring materials and keep
drives
away from heat-sensitive equipment and wiring.
- The service life of each
drive
depends on the ambient temperatures of the internal electrolytic capacitor.
Electrolytic capacitors last approximately 5 to 6 years under the conditions of 30 °C annual average temperature,
80 % load factor, and 20 hours or less average daily operation.
