Precautions
This user manual contains the necessary information regarding the installation and use of the
COVER series HS power supplies.
Before beginning installation and use, you are asked to read this manual carefully.
The UPS must be installed and configured by an authorized service center of the manufacturer
or distributor. In the case of installation by people without the required experience, there is a
risk of users being exposed to health or life. Persons not authorized to install may damage the
power supply, which in this case is not subject to warranty conditions.
COMPLETE STANDARDS
The appliance complies with CE-Directives 73/23 and 93/68 (low voltage safety) as well as
89/336 (EMC) and the following standards:
*IEC62040-1-1
*IEC/EN62040-2 EMC CLASS C3
*IEC62040-3
WARNING - Large leakage current
Connecting the protective conductor (PE) is essential and must be done before connecting
the remaining working cables (power supply, receiving, battery).
Grounding should be carried out in accordance with prevailing standards and practical on-
site knowledge.
The leakage current exceeds 3.5 mA and is less than 1000 mA.
When selecting RCCB or RCD devices for immediate operation, the transient and fixed
leakage currents that may occur during commissioning must be considered.
Automatic residual current circuit breakers (RCCBs) that are sensitive to DC unidirectional
(Class A) pulses and are insensitive to transient current pulses shall be selected.
Also note that the RCCB or RCD device will conduct the leakage current of the receiver.
Operation
There is dangerous voltage in the UPS housing. The risk of contact with such voltage is
minimized as the live parts are behind the enclosure. Additional internal protection guards
ensure that the device is protected in accordance with IP20 protection class.
Normal operation of the device, taking into account recommended operating procedures,
does not pose any risk to personnel.
All maintenance and service procedures require access to the inside of the machine and
should only be carried out by trained personnel.
Battery high voltage > 400 Vdc
All maintenance and installation work may be performed by a properly trained service
technician.
After connecting the battery the voltage at their terminals exceeds 400 Vdc and is potentially
fatal.
