9.1. Notes about

Important!

Ì

For use and operation as per the

requirements

1)

, a power supply with the feature “for use in

class 2 circuits” must be used.
Alternative solutions must comply with the following requirements:
a) Electrically isolated power supply unit with a max. open-circuit voltage of 30 V/DC and a limited

current of max. 8 A.

b) Electrically isolated power supply unit in combination with fuse as per UL248. This fuse should be

designed for max. 3.3 A and should be integrated into the 30 V DC voltage section.

Ì

For use and applications as per the requirements of

1)

, a connection cable listed under the UL

category code CYJV2 or CYJV must be used.

1) Note on the scope of the UL approval: the devices have been tested as per the requirements of UL508 and CSA/ C22.2 no. 14 (protection against electric shock

and fire). Only for applications as per NFPA 79 (Industrial Machinery).

9.2. Safety in case of faults

Ì

The operating voltage U

B

is reverse polarity protected.

Ì

The safety outputs are short circuit-proof.

Ì

A short circuit between the safety outputs is detected by the switch.

Ì

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

9.3. Fuse protection for power supply

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

outputs. The following rules apply:

Max. current consumption of an individual switch I

max

I

max

= I

UB

+ I

OD

+ I

FO1A

+

FO1B

I

UB

= Switch operating current (35 mA)

I

OD

= Load current of monitoring outputs (max. 50 mA)

I

FO1A+FO1B

= Load current of safety outputs FO1A + FO1B (2 x max. 200 mA)

Max. current consumption of a switch chain

Σ

I

max

Σ

I

max
