Chapter 3 Mechanical Installation
3.1 Precautions
• Do not install if HD3L is incomplete or impaired.
• When conveying HD3L, please employ suitable tools according to its weight. Avoid scratch to the product. Be
careful: rollover and drop may cause hurt.
• Make sure that HD3L is far from 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
HD3L is off and the voltage between (+) and (-) of the main circuit terminals is below 36V.
• It is required not only carry the keypad and the cover but also bottom enclosure of HD3L.
• Do not let wires, screws or residues fall into HD3L when installing.
3.2 Installation Site Requirement

• 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 HD3L so as to keep ambient temperature between
-10 - + 40℃;
• Install at where the vibration is less than 5.9m/s
2
(0.6g);
• Install at where the humidity is less than 95%RH and non-condensing location;
• HD3L meets IP20 and Pollution level 2 (Dry, none conducting dust pollution).
Note:
1. It needs derating use if running temperature exceeds 40
℃
. The derating value of the output current of
HD3L shall be 2% for each degree centigrade. Max. allowed temperature is 50
℃
.
2. Keep ambient temperature between -10 - +40
℃
. It can improve the running performance if install at
location with good ventilation or cooling devices.
