12.4 Weight Safety
!
!
This equipment is heavy
(max. 20 kg). Please lift and handle
with care to avoid strain or impact
injuries, and follow the
recommended installation
procedure. Install modules after
mounting mainframe in equipment
rack.
!
!
Do not use the handles to lift or carry
the mainframe. The handles are
designed for sliding the unit into and
out of the equipment rack, and not to
support its weight.
Use the underside edges of the
mainframe to lift and carry it.
12.5 Cabling
Cables for the AC mains and DC battery supplies
must be adequately rated for the expected
currents that it will be carrying. Using too thin a
cable can cause a safety hazard and will give
excessive voltage drop and operational failure.
12.6 EMC
In the close proximity of some radio frequency
transmitters, the signal to noise ratio of this
product may be reduced. If this occurs, re-
location of the equipment or the signal cables is
recommended.
12.7 Ground Loops
It is possible to form a ground loop (earth loop or
hum loop) when connecting pieces of audio
equipment using unbalanced connections that
provide alternative earth connections via their
cable screens.
Such ground loops result in audible ‘hum’ from
the system. See Section “5.4 Avoiding Ground
Loop Problems” (page 58) for recommended
cabling practices to avoid ground loops.
!
!
Never disconnect the mains earth
from the plug to attempt to cure a
ground loop. In the event of a fault,
the equipment casing could become
live.

battery.
Danger of explosion if battery is
