Mounting and Commissioning
This section is intended for experienced commissioning personnel. This personnel must
be familiar with the commissioning of protection and control systems, with the
management of power systems and with the relevant safety rules and standards.
Hardware modifications that might have to be made in certain cases are explained. For
primary testing, the connected protection unit must be switched on.
General
Mounting Instructions
Devices for DIN rail mounting are only permitted for operation in enclosed housings or
cubicles, and may only be mounted in locations that are accessible to qualified
personnel only.
The DIN rail housing is intended for mounting on a symmetrical mounting rail according
to EN 60715.
For mounting, the device is swung downwards onto the DIN rail, pressed downwards,
and snapped on by pressing backwards. The connection is released by lifting the
locking element on the underside of the device using a flat screwdriver to loosen it from
the mounting rail. The device can then be lifted off the DIN rail in the opposite direction
to the snap-on movement.
The data lines for electrical interfaces, e.g. RS232 or RS485, must be encased in
screened, earthed cables.
The FO cables must comply with the connection standard of the device (tech. data).
The mounting location should be as vibration-free as possible. The permissible ambient
temperature (operating and functional temperature) must be observed (see Technical
Data).
Operation outside the functional temperature range or in environments with increased
air pollution can lead to malfunctions, failure, and destruction of the device (note the IP
class of the device).

Warning of improper transport, storage,
installation or mounting of the device
Failure to observe these precautions can result in death, personal
injury, or substantial material damage.
Problem-free and safe use of this device depends on proper transport,
storage, installation and mounting of the device. All warnings and
instructions in this manual must be taken into account.
In particular, the general installation and safety regulations for
work with power current equipment (e.g. ANSI, IEC, EN, DIN, or
other national and international regulations) must be observed.
