2.3 Electrical and Mechanical Safety
Warning
Risk of injury due to electricity.
● All K-BOW racks must be connected to a protective earthing conductor.
● It is recommended to earth the remote units to ensure their electromagnetic
compatibility (EMC).
● Do not connect system components to the power supply during installation.
Connection to the power supply must be performed by a trained, quali ed and
authorised specialist.
● Only install and uninstall system components if they are de-energised.
Exceptions:plug-in modules. For PSU modules, observe the following points:
– Installation: First, push the PSU module completely into the PDU/FSR/BSR, then
plug the power supply cable into the PSU module.
– Removal: First, unplug the power supply cable from the PSU module, then remove
the PSU module from the PDU/FSR/BSR.
● Do not touch parts that are at a hazardous voltage. This also applies if fuses inside the
device have been removed.
The system has a supply voltage of up to 240V alternating voltage. If touched, there is
a risk of death due to electric shock.
● Install the socket near the equipment and make sure it is easily accessible.
● If cables are run in cable trays, earth cables and live cables must be separated by walls
from RFcoaxial and breoptic cables. Observe the guidelines in the
K-BOW Installation
Manual for HUB.
● An appropriate fuse protection for all power supply feed lines of the K-BOW system
protection must be provided by the customer.
All power supply feed lines of the K-BOW system must be equipped with an
overvoltage protector for medium voltage loads and automatic circuit breakers (delay
fuse) of 10Amax. for overcurrent protection.
The correct performance must be checked and recorded according to current regulations.
● Only IEC-60320 C13/C14 power supply cables and appliance couplers speci ed for
10Amin. continuous load are allowed.
● Unplug the power cable(s) of a switched-mode power supply to completely disconnect
the power supply unit and the connected devices from the mains. If redundant
switched-mode power supplies are used, unplug the power cables of all power supply
units concerned.
● All fuses inside the system may only be replaced by original parts.
