Safety instructions

WARNING!
Electrical systems may only be constructed, extended, modified and main-
tained by an authorised group of personnel.
The power supply unit is intended for the use in an operating area with
restricted access.
The power supply unit is suitable for installation at a maximum height
of 2 meters only.
The power supply unit is suitable for mounting above a
non-combustible surface only.
Work must only be carried out when the system has been disconnected from
the power. Before starting installation and service work, the input voltage
must be disconnected and secured to prevent it being reconnected. If this is
not oberserved, touching live parts can result in death or serious injury.
The supply voltage must be connected in accordance with the regulations
that apply in the country concerned (in Germany's case, these are VDE 0100
and VDE 0160).
Protective and isolation equipment for disconnecting the input voltage must
be provided.
If the values specified in the technical data are exceeded, there is the risk of
the device overheating, which may result in the supply voltage device being
destroyed and the electrical safety being impaired.
Safe isolation of the AC and DC supplies must be ensured at the premises.
General safety instructions on handling batteries must be observed. In par-
ticular, it is important to ensure that sufficient ventilation is available to pre-
vent the build-up of explosive hydrogen and air mixtures.
