4.4.16 Line protection and earth-leakage circuit breaker
• Install fuses at the beginning of the mains cable behind supply bus junction (see
basic unit wiring diagram).
• SEW-EURODRIVE recommends that you do not use RCDs. However, if an earth-
leakage circuit breaker is stipulated for direct or indirect protection against contact,
observe the following:
•

can cause direct current in the PE conductor. If a residual current
device (RCD) or a residual current monitoring device (RCM) is used for protection
in the event of a direct or indirect contact, only a type B RCD or RCM is permitted
on the supply end of the MOVITRAC

.
4.4.17 TF thermistor and TH bimetallic switch
The winding temperature is monitored using TF thermistors or TH bimetallic switches.
Connect TF or TH to the TF output VOTF and the TF input DI05TF of MOVITRAC
®
B.
Set digital input DI05TF to TF signal. The temperature will then be monitored by
MOVITRAC
®
B; no additional monitoring unit is required.
You can also connect TH bimetallic switches to 24 V IO and a digital input. Set the digital
input to "/External fault".
