9.1. Notes about
Important!
Ì
This device is intended to be used with a Class 2 power source in accordance with UL1310.
As an alternative an 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 UL248. 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
possibly lower connection ratings for your device (refer to the technical data).
Ì
For use and application as per the requirements of
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).

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 the current required for
the outputs. The following rules apply:

9.4. 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.
