Terminal box

Hazardous voltage
Electric motors have high voltages. When incorrectly handled, this can result in death or severe
injury.
Switch off the machine so that it is in a no-voltage condition before you open the terminal box.
NOTICE
Damage to the terminal box
If you incorrectly carry out work on or in the terminal box, this can result in material damage.
You must observe the following to avoid damaging the terminal box:
• Ensure that the components inside the terminal box are not damaged.
• It must be ensured that there are no foreign bodies, dirt or moisture in the terminal box.
• Close the terminal box using the original seal so that it is dust tight and water tight.
• Use O-rings or suitable flat gaskets to seal entries in the terminal box (DIN 42925) and other
• Please observe the tightening torques for cable entries and other screws.
• Do not apply manual force to the terminal board. The terminal board mountings are

Direction of rotation

The standard motors are suitable for clockwise and counter-clockwise rotation.
For defined directions of rotation (direction of rotation arrow), appropriately connect the line
power cables.
• If you connect the line cables with phase sequence L1, L2, L3 at U, V, W or according to NEMA
at T1 T2 T3 , then the machine rotates in the clockwise direction.
• If you interchange 2 connections, e.g. L1, L2, L3 at V, U, W or according to NEMA at T2 T1 T3,
then the machine rotates counterclockwise.
