The device does not feature protection against water and may therefore only be operated and
connected in dry rooms. It must not be exposed to splash water or drip water, condensation or
similar effects of water, as this may impair the isolation from the mains voltage.
The electrical system supplying current to the device, e.g. a house installation, must incorporate
safety devices against excessive current, earth leakages and short-circuiting in accordance with
EN 60950-1.
All adhere to all applicable national safety regulations and standards.
Both mains plugs are used as a mains voltage disconnect unit in the event of servicing and in the
event of danger, and must therefore be accessible and be able to be operated at any time. The
device is operational as soon as one mains plug is connected to the mains voltage.
Do not install the unit in locations with excessive dust formation, as this may impair the isolation
from the mains voltage.
Excess mechanical loads (e.g. falling, impacts, vibrations) may damage the insulation used to
provide protection from mains voltage.
High excess currents (lightning strike, surges in the power utility grid) may damage insulation used
to provide protection from mains voltage.
If there is no information about intended use (e.g. operating site, ambient conditions), or the oper-
ating manual does not include the corresponding information, then you must consult the manufac-
turer of this device to ensure that the device may be installed. If you do not receive any information
on this from the manufacturer, do not start operating the device.
Disconnect devices with damaged power cables from the mains power (unplug the power supply
plug).
Electromagnetic compatibility (EMC)
In order to avoid malfunctions from occurring when operating radio and telecommunications equip-
ment, as well as other operating units or broadcasting services, the following points must be observed:
Before installation, the device must be checked for mechanical damage. Damaged or bent covers
or housings may not be used.
During operation, the device must always be covered by the components provided for this
purpose. Operation with an opened cover is not permitted.
The braided line or the contact springs may not be damaged or removed.
Maintenance
The operating display only shows whether the DC current, which supplies the device components,
has been disconnected. However, operating displays (on the power supply unit or the device) that
are not lit up in no way indicate that the device is completely disconnected from the mains. There
may still be voltages in the device that are dangerous to touch. You may therefore not open the
device.
Read carefully: EN 60728-11 – Part 1, Safety requirements / No service tasks during electrical
storms!
Repair
Repairs may only be performed by the manufacturer. Improperly performed repairs may result in
considerable dangers for the user.
Do not start operating devices with a damaged power cable, and instead have them repaired by
the manufacturer.
If malfunctions occur, the device must be disconnected from the mains and authorised experts
must be consulted. The device may need to be sent to the manufacturer.
