}
Use copper wire that can withstand 60/75 °C.
}
Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
}
Do not switch low currents using contacts that have been used previously with high cur-
rents.
}
Ensure the wiring and EMC requirements of EN 60204-1 are met.
}
When used with converters: Please comply with the information regarding installation and
wiring in the documentation of the converter. Use screened cable for the wiring between
the PSWZ X1P and the motor. Connect the cable screening on the motor.
}
Protect the measuring circuits according to the conductor cross section.
}
Single-phase motor: Connect terminal L1 directly to motor connection terminal L, and ter-
minal L3 directly to motor connection terminal N. Connect terminal L2 directly to the ele-
ment that switches the motor on (contactor, converter, etc.). Separate cables with separ-
ate insulation should be used for the measuring voltages L1 and L2. The cables should
also be physically separate.
}
Three-phase motor: Connect the connection terminals L1, L2 and L3 directly to the motor
connection terminals L1, L2 and L3.

not
connect the terminals labelled "*".
