Section 3.1 Pin assignment; Supply voltage fuse protection
The module has neither short-circuit protection nor overload protection. Protect the module
from being destroyed by impermissible high current and install a fine fuse in the supply line.
The maximum rated current of the fine fuse depends on the hardware function status (FS) of
the module.

Section 6.1 Technical specifications, Switching frequency with inductive load
The switching frequency of the outputs with inductive loads is max. 0.5 Hz.
Higher switching frequency is possible in spite of this, and depends on the alternating voltage
and switched inductors or the power factor of the electric motor used.

• Power factor of the electric motor cos φ > 0.35
• Electric motor must only be turned off after
startup (no jogging mode).
Electric motors which are turned off during
startup could create inductive shutoff voltages
