DANGER
Observe the safety precautions in chapter 2 of this manual. --> See "Safety Precautions"
on page 2 – 15!
Caution
The following inspection, measuring and testing equipment is only intended for testing
machines!
Caution
Encoder cables, etc., are no longer continuously shielded when the test adapter is
connected.
Caution
When using grounded measuring equipment (e.g., oscilloscope with power connection),
always the socket of the machine's electrical cabinet should be used for power supply.
Compensating currents caused by different earth potentials can thus be avoided!
Caution
For measuring voltages, first connect to 0 V and only then to the voltage to be measured!
Caution
Always observe the Operating Instructions of PWM 9 as well as the Operating
Instructions of PWT 10/17/18 and IK 215!
