EN
11.2. Safety in case of faults
Ì
The operating voltage UB and the solenoid voltage IMP are reverse polarity protected.
Ì
The safety outputs FO1A/FO1B are short circuit-proof.
Ì
A short circuit between FO1A and FO1B is detected by the locking module.
Ì
A short circuit in the cable can be excluded by laying the cable with protection.
11.3. Fuse protection for power supply
The power supply must be provided with fuse protection depending on the number of locking modules and current required
for the outputs. The following rules apply:
Max. current consumption of an individual locking module I

11.4. Requirements for connecting cables
CAUTION
Risk of damage to equipment or malfunctions as a result of incorrect connecting cables.
Ì
Use connection components and connecting cables from EUCHNER.
Ì
On the use of other connection components, the requirements in the following table apply. EUCHNER
provides no warranty for safe function in case of failure to comply with these requirements.
Observe the following requirements with respect to the connecting cables:
