12.1.  Notes about 

Important!

 

Ì

This device is intended to be used with a Class 2 power source in accordance with UL1310 

1)

.

As an alternative a LV/C (Limited Voltage/Current) power source with the following properties can 
be used:
-  This device shall be used with a suitable isolating source in conjunction with a fuse in accordance 

with UL 248. The fuse shall be rated max. 3.3 A and be installed in the max. 30 V/DC power supply 

to the device in order to limit the available current to comply with the 

 requirements. Please note 

possibly lower connection ratings for your device (refer to the technical data).

1) Notice on the scope of the UL approval: only for applications as per NFPA 79 (Industrial Machinery). The devices are tested in accordance with UL 508 (protection 

against electric shock and fire). 

12.2.  Safety in case of faults

 

Ì

The operating voltage UB is reverse polarity protected. 

 

Ì

The safety outputs FO1A/FO1B are short circuit-proof.

 

Ì

A short circuit between FI1A and FI1B or FO1A and FO1B is detected by the device. 

 

Ì

A short circuit in the cable can be excluded by laying the cable with protection.

12.3.  Fuse protection for power supply

The power supply must be provided with fuse protection depending on the number of devices and the current required for 

the outputs. The following rules apply:
