General Installation Instructions
Please consider besides these general instructions also any product-specific
instructions in the “Installation” chapter of this manual.
B1
Unpacking
Check the equipment for any transport damage. If the unit is mechanically
damaged, if liquids have been spilled or if objects have fallen into the unit,
it must not be connected to the AC power outlet, or it must be immediately
disconnected by unplugging the power cable.
Repair must only be per-
formed by trained personnel in accordance with the applicable regulations.
B2
Installation Site
Install the unit in a place where the following conditions are met:
• The temperature and the relative humidity of the environment must be
within the specified limits during operation of the unit. Relevant values
are the ones at the air inlets of the unit.
• Condensation must be avoided. If the unit is installed in a location with
large variation of ambient temperature (e.g. in an OB-van), appropriate
precautions must be taken before and after operation (for details on this
subject, refer to Appendix 1).
• Unobstructed air flow is essential for proper operation. Air vents of the
unit are a functional part of the design and must not be blocked in any
way during operation (e.g. by objects placed upon them, placement of
the unit on a soft surface, or installation of the unit within a rack or
piece of furniture).
• The unit must not be heated up by external sources of heat radiation
(sunlight, spot lights).
B3
Earthing and Power Supply
Earthing of units with mains supply (class I equipment) is performed via
the protective earth (PE) conductor integrated in the mains cable. Units
with battery operation (< 60 V, class III equipment) must be earthed sepa-
rately.
Earthing the unit is one of the measures for protection against electrical
shock hazard (dangerous body currents). Hazardous voltage may not only
be caused by a defective power supply insulation, but may also be intro-
duced by the connected audio or control cables.
If the unit is installed with one or several external connections, its earthing
must be provided during operation as well as while the unit is not operated.
If the earthing connection can be interrupted, for example, by unplugging
the mains plug of an external power supply unit, an additional, permanent
earthing connection must be installed using the provided earth terminal.
Avoid ground loops (hum loops) by keeping the loop surface as small as
possible (by consequently guiding the earth conductors in a narrow, paral-
lel way), and reduce the noise current flowing through the loop by inserting
an additional impedance (common-mode choke).
