7.3 Demands on the electrical power supply
For all important data, see ZRequirements to the energy supply: power supply– from
page 27.
Minor deviations from requirements in the power supply can lead to malfunctioning of the
device. If the power supply deviates too much from the requirements, the device can be
destroyed.
The devices may only be operated in secondary surroundings (e.g. an industrial environ-
ment).
The destruction of the device can cause personal injury.
7.4 Requirements for the connection cables
h Take into account IEC/EN 60204-1, Chapter 13 when selecting the cable.
h The protective ground cross-section of the cable must be compliant with IEC/
EN
60204-1, section 5.2, tab. 1.
h A fixed connection for the protective ground conductor is mandatorily specified for op-
eration of the device.
h Use copper cable approved for a minimum of 60 °C (drives < 3 x 100 A) or 75 °C
(drives 3 x 100
A), if UL 508C is in consideration.
For further details (e.g. maximum permissible length), see ZCables– from page 177.
7.5 Protection of the device and accordingly of the cable
In order to protect this device and accordingly the cables against overload and possible
damages / destruction due to the power supply, cable protection fuses and device pro-
tection fuses must be installed. Data of the required fuses see ZFuses– from page 191.
DANGER!
Risk of fatal injury from electrical current!
If the requirements for the power supply are not complied, the device can be dam-
aged or destroyed, thereby greatly endangering individuals.
Therefore:
m Prior to installation, ensure that the prerequisites for power supply have been ful-
filled.
