HY Series Power Supplies
Operating Instructions
1.0 Mains Connection
The design of the unit meets the requirements of safety class I according to EN 61010-1, i.e. all metal parts
accessible from outside and exposed to contact are connected with the protective conductor of the supply
network.
Power is supplied via a mains cable with earthing contact.
1.1Installing the power supply
The power supply should not be operated close to equipment that develops heat. To protect the power supply
from thermal overload the air vents must not be covered and a free space of about 10 cm should be ensured.
1.2Switching on
The power supply is switched on using the power switch at the front. The power switch separates the unit
completely from the primary side of the transformer. Refer to para 3.1 and 3.2 for correct mains voltage and
fuse settings.
1.3EMC
The power supply is interference-free according to EN 50081-1 and EN 50081-2. In order to fulfil the limit
values in line with present standards, it is absolutely necessary that only cables which are in perfect condition
be connected to the unit.
1.4Inspection and Maintenance
If service is needed, due attention should be paid to the regulations according to VDE 0701. The power supply should only be repaired by trained personnel.
1.5Warranty
The perfect working order of the power supply is guaranteed for 12 months as from delivery.
There is no warranty for faults arising from improper operation or from changes made to the power supply or
from inappropriate application.
If a fault occurs please contact or send your power supply to:
The power supply should be sent in appropriate packing - if possible in the original packing. Please enclose a
detailed fault report (functions working incorrectly, deviating specifications and so on) including unit type

Would you also kindly verify warranty cases by enclosing your supply delivery note. Any repairs carried out
without reference to a valid warranty will initially be at the owner’s expense.
Should the warranty have expired, we will, of course, be glad to repair your power supply as per our General
Terms Of Assembly And Service.
