11.2. Safety in case of faults
Ì
The safety outputs FO1A/FO1B are short circuit-proof.
Ì
A short circuit between FO1A and FO1B is detected by the interlocking 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 interlocking modules and the current
required for the outputs. The following rules apply:
Max. current consumption of an individual interlocking module I

FO1A+FO1B
= Load current of safety outputs FO1A + FO1B (2 x max. 150 mA)
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 require-
ments.
Observe the following requirements with respect to the connecting cables:
