5.7.1 PTC thermistor connection
Discrepancies can arise due to the various motor manufactur-
ers and motor sizes. Observe the documents accompanying
the motor and note the information in the terminal box cover.
to the tripping unit
Important!
- Measurement voltage of max. 2.5 V direct current!
- Only operate in connection with a tripping unit!
- Use a measuring bridge or ohmmeter to check the resist-
ance.
- Configuration of terminals A1 and A2 (if available) in the
event of a breakdown of a PTC thermistor.

Variable frequency operation
Important!
Follow the operating manual included in delivery.
Important!
Pumps of the herborner.X-PM model are only suitable for
variable frequency operation.
Variable frequency drives can also be connected in a direct
mounting configuration for pumps of the herborner.X and
herborner.X-PM models up to 26.4 kW (only wall mounting
configuration for herborner.X-C models).
Possible frequency regulation of pumps is possible depend-
ing on the operating conditions.
