Requirements for connecting the signal contact
Requirements for connecting the supply voltage
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 60950-1 or ES1 as per IEC/EN 62368-1.
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 47.

Device variant
Requirements
All variants
All
of the following requirements are complied with:
The supply voltage corresponds to the voltage specified on the type
plate of the device.
The power supply conforms to overvoltage category I or II.
The power supply has an easily accessible disconnecting device (for
example a switch or a plug). This disconnecting device is clearly
identified. So in the case of an emergency, it is clear which
disconnecting device belongs to which power supply cable.
The cross-section of the ground conductor is the same size as or
bigger than the cross-section of the power supply cables.
Relevant for North America:
The power supply cables are suitable for ambient air temperatures of
at least +167 °F (+75 °C). The wires of the power supply cables are
made of copper.
