
National and international safety regulations

Verify that the electrical installation meets local or nationally applicable
safety regulations.

Grounding the device
Grounding the device is by means of a separate ground connection on the
device.

Ground the device before connecting any other cables.

Disconnect the grounding only after disconnecting all other cables.

Shielding ground
The overall shield of a connected shielded twisted pair cable is connected
to the ground connector on the front panel as a conductor.

Beware of possible short circuits when connecting a cable section with
conductive shielding braiding.

Requirements for connecting electrical wires

Before connecting the electrical wires, always verify that the
requirements listed are complied with.
All of the following requirements are complied with:

The electrical wires are voltage-free.

The cables used are permitted for the temperature range of the application case.
 Only for device variants featuring supply voltage with the characteristic value CC:
The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1.
Table 1: General requirements for connecting electrical wires
All of the following requirements are complied with:

The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1.
 The connected voltage is limited by a current limitation device or a fuse.
Observe the electrical threshold values for the signal contact.
See “General technical data” on page 44.
 The cross-section of the ground conductor is the same size as or bigger than the cross-
section of the power supply cables.
