Chapter 3 Mechanical Installation
3.1 Precautions
• Do not install if controller is incomplete or impaired.
• Please see the controller size and weight to take appropriate tools for handing, avoid harming from sharp edges
or injured by a dropped controller.
• Make sure that controller is far from the explosive and flammable things.
• Do not do wiring operation until power supply is cut off for more than 10 minutes, the internal charge indicator of
controller is off and the voltage between (+) and (-) of the main circuit terminals is below 36V.

• Do not install at flammable, explosive, corrosive gas and liquid location;
• Do not install at oily dust, fiber and metal powder location;
• Be vertical installed on fire-retardant material with a strong support;
• Make sure adequate cooling space for controller so as to keep ambient temperature between
-10 - +40°C;
• Install at where the vibration is 3.5m/s
2
in 2 - 9Hz, 10m/s
2
in 9 - 200Hz (IEC 60721-3-3);
• Protection level of controller is IP20 and pollution level is 2 (dry, non-conducting dust pollution).
Note:
1. It needs derating use running temperature exceeds 40°C. The derating value of the output current of
controller shall be 2% for each degree centigrade. The Max. allowed temperature is 50°C.
2. Keep ambient temperature between -10 - +40°C. It can improve the controller running performance if
install at location with good ventilation or cooling devices.
