Release 11 09/2020
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
(e.g., 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 cords are suitable for ambient air temperatures of at least
167 °F (75 °C). The power cord wires are made of copper.
Only for device
variants featuring
supply voltage with
the characteristic
value CC:
The wire diameter of the supply voltage at the input is at least 1 mm²
(North America AWG16).
The following requirements are
alternatively
complied with:
Alternative 1
Relevant for North America:
The power supply complies with the requirements
as per NEC Class 2
Alternative 2
All
of the following requirements are complied with:
The power supply complies with the
requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1.
A fuse suitable for DC voltage is located in the
plus conductor of the power supply.
The minus conductor is on ground potential.
Otherwise, a fuse is also located in the minus
conductor.
Regarding the properties of this fuse:
See “General technical data” on page 44.
Only for device
variants featuring
supply voltage with
the characteristic
value K9 or KK:
All
of the following requirements are complied with:
Disconnect device for equipment supplied from IT supply system,
shall disconnect both poles of mains supply.
a
Supply with DC voltage:
A fuse suitable for DC voltage is located in the plus conductor of the
power supply.
The minus conductor is on ground potential. Otherwise, a fuse is also
located in the minus conductor.
Regarding the properties of this fuse:
See “General technical data” on page 44.
Supply with AC voltage:
A fuse is located in the outer conductor of the power supply.
The neutral conductor is on ground potential at both voltage inputs.
Otherwise, a fuse is also located in the neutral conductor.
Regarding the properties of this fuse:
See “General technical data” on page 44.
The wire diameter of the power supply cable is at least 0.75 mm²
(North America: AWG18) on the supply voltage input.
a. IT supply system according to the technical standard UL 60950-1
