Chapter 1 Safety precautions
Important information Read these operating instructions before starting the unit. They provide you with
important information on the use, safety and maintenance of the units. This helps
you to protect yourself and prevent damage to the unit.
Information intended to help you to avoid death, bodily harm or considerable
damage to property are highlighted by the warning triangle shown here; it is
imperative that this information be properly heeded.
The operating instructions are intended for trained professional electricians familiar
with the safety standards of electrical technology and industrial electronics.
Store these operating instructions in an appropriate place.
The manufacturer is not liable if the information in these operating instructions are
not complied with.
Safety Components inside the units are energized with electricity during operation.
For this reason, mounting and maintenance work may only be performed by
professionally-trained personnel while observing the corresponding safety
regulations.
The repair and replacement of components and modules may only be carried out
by the manufacturer for safety reasons and due to the required compliance with
the documented unit properties.
The units do not have a power switch. They are operative as soon as the operating
voltage is applied.
Intended use The units are intended for use in industrial environments. They may only be
operated within the limit values stipulated by the technical data.
When configuring, installing, maintaining and testing the units, the safety and
accident-prevention regulations relevant to use in each individual case must be
complied with.
Trouble-free, safe operation of the units requires proper transport, storage,
installation, mounting and careful operation and maintenance of the units.
Mounting and installation The attachment options for the units were conceived in such a way as to ensure
safe, reliable mounting.
The user must ensure that the attachment hardware, the unit carrier and the
anchoring at the unit carrier are sufficient to securely support the unit under
the given surrounding conditions.
The units are to be mounted in such a way that they can be opened up while
mounted. Sufficient space for the cables must be available in the unit near the
cable infeed.
Sufficient space is to be kept clear around the units to ensure air circulation and to
prevent the build-up of heat resulting from use. The relevant information must be
heeded in the case of units ventilated by other means.
When the housing fasteners are opened, the front frame of the housing
hinges out upward or downward (depending on the unit version)
automatically.
