9.2 Temperature detection
GEFAHR
Electric shock by sensors without protective separation!
a) Only use sensors with basic insulation.
b) Only sensors with double insulation (basic insulation plus additional insulation)
are permitted up to the specified year/week of manufacturing (see specifica-
tion).
ACHTUNG
Malfunctions due to wrong cables or laying!
Malfunctions of the control due to capacitive or inductive coupling
a) Do not lay the cables of the motor temperature sensor (also shielded) together
with the control cables.
b) Cables of the motor temperature sensor within the motor cables are only per-
missible with double shielding.

to the SELV voltage of the control card. A
system voltage of 300 V is defined (Phase – PE).
A switchable temperature evaluation is implemented in COMBIVERT. The desired
operating mode can be adjusted by software (dr33).

9.2.1 Operation without temperature detection
Use of the COMBIVERT without evaluation of the temperature input:
Switch off evaluation (pn33 =7) or install bridge between terminal TA1 (X1C.5) and
TA2 (X1C.6) (dr33=1).
