Motor connection
Connection via terminal box
Observe the notes on wiring, data on the nameplate, and the connection diagram in the
terminal box.
The connection must ensure a continuous and safe electrical supply:
•
No protruding wire ends
•
Use assigned cable end fittings
•
Ensure good electrical conductivity of the contact (remove paint residues) if an additional
PE connection is used
•
Establish a safe protective earth connection
•
After the connection is completed, make sure that all connections on the terminal board
are firmly tightened
•
The terminal box has to be free of foreign bodies, dirt, and humidity
•
All unused cable entries and the terminal box itself must be sealed so that they are dust-
tight and waterproof
The smallest air gaps between uncoated, live parts and against earth must not fall below the
following values:
Minimum requirements for basic insulation
according to IEC/EN 60664-1 (CE)
Higher requirements for UL design
