Using the environment：
Ambient air temperature varies with the seasons but does not exceed 40℃;The ambient air relative temperature is greater than 90% (when the temperature is 25℃).
Note：
The specifications listed in the sample (Type A) are standard types. The following types can be made according to the special requirements of customers：
1.Change the L1, L2.L3 size structure;
2.It is made into a vertical structure with rainproof cover (the standard type is horizontal);
3.Made left outgoing line (standard type is right outgoing line), top outgoing line structure;
4.The machine housing can be equipped with brakes, encoders and other structures;
5.Fan motor can be different voltage and different frequency of the electrical system, improve the protection level, improve the insulation level and other special requirements (standard model of electrical system 380V50HZ, protection level IP55, insulation level F).
