Wiring of the actuators
using a 20-pin front connector
1) Fuses on this module are only supplementary. External surge current protection (suitable
for tap circuits conforming to local regulations for electrical engineering) is required in the
supply lines of the load circuit.
2) Possible errors:
- no load voltage
- defective fuse
- output overload
3) If an overload condition is detected, the output is disabled for the duration of ca. 2.4 s.
