X531-X536 temperature sensor inputs

Terminal

Max. connectable cross-section: 1.5 mm

Measuring current via the temperature sensor connection: 2 mA

Risk of electric shock!

Only temperature sensors that meet the safety isolation specifications stipulated in

EN 61800-5-1 may be connected to terminals "+Temp" and "-Temp".

If these instructions are not complied with, there is a risk of electric shock!

NOTICE

The KTY temperature sensor must be connected with the correct polarity. A sensor

connected up with the incorrect polarity cannot detect if the motor overheats.

NOTICE

When connecting several temperature sensors, the individual sensors must be separately

connected to "+ Temp" and "- Temp".

It is not permissible to jumper the "+ Temp" and "- Temp" signals between the individual

terminal blocks!

NOTICE

When connecting temperature sensors with 3 wires, a jumper must be inserted between

X53x.2 and X53x.4.
