3.
For compact devices, detach the internal yellow-green wire from the connection point for
PE.

Insulation test
4.
In the case of cabinet units, remove the "output filter" board -A9 or disconnect its ground
connection.
5.
You can find the board at motor terminals -X0:U2, V2, W2.
6.
In the case of the "radio interference Class A" option, also disconnect the input side radio
interference suppression capacitor -C10 from the line connection busbar at
-X0:U1, V1, W1 or the main switch.
7.
Perform the test with maximum DC 500 V for a maximum of 2 minutes between the U1,
V1, W1, U2, V2, W2 jumper and the enclosure.
8.
After completion of the test, connect the output voltages U, V, W with PE.
9.
Undo the above actions.
7.2
Checks with mains power supply and without motor
The load-dependent actual values, e.g. "I-motor", "T-motor" or "P-motor" are also displayed
without motor. They are 0 in this case.
●
Perform the following tests and configurations without motor connection. This prevents
damage to the motor in the case of errors.
If tests without motor are not possible, then perform the tests with motor.
●
The "peripheral board 2 / 4" option which can be recognized from the last position of the
type designation on the rating plate has safety-oriented inputs.
Check these inputs according to the "Safe torque off" (Page 42) description.
