Safety precautions
ATTENTION
Before working on the
base unit OKB 1000 please
read the following safety
precautions carefully !
• The unit should only be
opened by qualified persons.
• For removement and/or
installation of a module the base
unit must always be currentless !
• The unit may be only operated with
a mains voltage of 230 V~/50 Hz.
• Lay cables that they
cannot be tripped over !
• According to the regulations
EN 50 083/VDE 0855 the plant
must correspond to the safety
regulations e.g. grounding,
potential equalization, etc.
• The equipment may not be exposed
dripping or splash-water. In case
of condensed water formation
wait until the device is dry again.
• The ambient temperature must not
50 °C. Don’t cover the louvers
of the device. To strong heat effect or
accumulation of heat impairs the life
span of the equipment and can be a
source of dan-ger. In order to prevent
an accumulation of heat and to guar-
antee a good aeration, the equipment
should be only perpendicularly
installed (e.g. at a wall).
• The unit must not be installed
directly above or in the immediate
vicinity of heat sources (e.g. heating
ele-ments, heating systems or
similarly), where the equipment is
exposed to heat radiation or oil vapour.
• Due to the risk of fire by
overheating or lightning strike it
is recommendable to install the
equipment on a non-combustible base.
• Fuses should be changed only from
authorized technical personnel. Only
fuses of the same type may be used
• Precautions to ensure the electro
magnetic com-patibility (EMV): All
covers and screws must tightly
be fitted and should be tightly
fastened. Contact feathers should
not be oxidized or deformed.
