Main Power Distribution Box

The main terminal box is located at the top of the motor (viewed from the motor shaft extension end), with the outlet ports adjustable in four directions. However, for terminal boxes with a center height of 160mm or more, when the outlet ports face backward (towards the non-shaft extension end) due to the influence of the lifting ring, it is necessary to remove the lifting ring after the motor is hoisted into place at the installation site, open the terminal box cover, loosen the bolts connecting the terminal box to the motor base, and adjust the outlet ports to face backward.

Environmental Conditions:

Ambient air temperature: -15°C to +40°C. Altitude: Not exceeding 1000m.

Special environmental air temperature and altitude requirements should be agreed upon by both parties; please specify at the time of order.
