Motor protection
Motor protection is possible by connecting thermostats

TB
”
(thermal contacts) or thermistors
“
TP
”
(PTC).
The jumper
“
J1
”
in the connection space must be plugged according to the used thermal protectors.
Motor with thermistors
“

”
For motor with thermistors
“

”
the jumper
“

”
must be plugged at the top.
A maximum of six individual thermistors (DIN 44081 or DIN 44082) may be connected in series to
a single device.

Possibilities for re-starting after the drive has cooled down (terminals

•
By switching the mains voltage off and then on again.
•
Via a digital input for remote control (ON/OFF enable).
Danger due to electric current
An outside voltage may never be connected to the terminals
