Electrical connection
6.1 Connecting the machine
For defined directions of rotation (direction of rotation arrow), appropriately connect the line
power cables.
• If you connect line cables with a phase sequence of L1, L2, L3 at U, V, W, the resulting rotation
is clockwise.
• If you interchange two connections, e.g. you connect L1, L2, L3 to V, U, W, the resulting
rotation will be counter-clockwise.

Cable entry
Plastic transport plug on terminal box Ex db
For shaft heights 100 up to 355, the cable entry thread in the terminal box is closed and sealed
using a plastic sealing plug. The plug prevents the ingress of foreign bodies in the terminal box
during transport to the installation site and during possible storage. The plastic plug is not
suitable for use in hazardous zones according to IEC / EN 60079-10-1 or IEC / EN 60079-10-2.
Replace the plastic plug by a cable gland certified according to IEC / EN 60079-14 or appropriate
sealing plug.
Certified cable entries, thread adapters and sealing plugs
Only use sealing plugs, cable glands and conductor glands or thread adapters that are suitable,
certified and marked for use in the respective explosion protection type and degree of protection
(IEC / EN 60079-14) or the appropriate country regulations.
Terminal box
The number and size of the cable entry tapped holes is provided in the machine dimension
drawing.
Inserting cables into the terminal box
1. Only use cable entries that are suitable for the cables.
2. Only use cable entries and cables suitable for the prevailing ambient temperature.
3. Ensure that the power cables are strain relieved when inserting them in the terminal box.
