Assembling; Insulation Resistance And Polarization Index - Siemens SIMOTICS M-1PH8 Operating Instructions & Installation Instructions

Assembling

When carrying out any work on the machine, observe the general safety instructions
(Page 13) and the specifications contained in DIN EN 50110‑1 as regards working safely with
and on electrical machines.
Note
Loss of conformity with European directives
In the delivery state, the machine corresponds to the requirements of the European directives.
Unauthorized changes or modifications to the motor lead to the loss of conformity with the
European directives.
Explosion hazard when making modifications to the machine
Substantial modifications to the machine are not permitted – or may only be performed by
the manufacturer. Otherwise an explosion can occur in an explosive atmosphere. This can
result in death, serious injury or material damage.
Please contact the Service Center, if necessary.
CAUTION
Heat-resistant mounting parts
The motor components get very hot during operation. High temperatures can damage
mounting parts such as the cable insulation.
● Temperature-sensitive parts such as normal cables or electronic components must not
● Only use heat-resistant mounting parts. The connecting cables and cable entries must be

Insulation resistance and polarization index

Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
