Safety precautions
Before you use our products, read the manual
carefully and observe all the safety precautions. They
will protect you and help to avoid equipment
failures. Keep this manual in a safe place so that it is
available for future reference.
If you supply d&b products, please draw the
attention of your customers to these safety
guidelines. Enclose the relevant manuals with the
systems. If you require additional manuals for this
purpose, you can order them from d&b (order form
on the last page).
Information regarding use of the E-PAC
The device complies with the electromagnetic compatibility
requirements of EN 55103 (product family standard for audio,
video, audio-visual and entertainment lighting control apparatus
for professional use) for the environments E1 (residential), E2
(business and commercial), E3 ( outdoor use in urban areas) and
E4 (outdoor use in rural areas).
Acoustic interference and malfunctions may occur if the unit is
operated in the immediate vicinity of high-frequency transmitters
(e.g. wireless microphones, mobile phones, etc.). Damage to the
mainframe is unlikely, but cannot be excluded.
To meet the EMC requirements, use only shielded cables with
properly connected plugs for all signal terminals (INPUT, INPUT
LINK, MIX IN).
The following information is intended to prevent fires and possible
electric shocks:
The E-PAC is a protective class 1 unit. Make sure that the earth
(ground) contact is attached when the unit is in operation. A
missing earth (ground) contact may lead to dangerous voltages in
the housing and controls.
To reduce the possibility of audible hum the mainframe signal
ground (XLR pin 1) to earth (ground) connection has a high
impedance. It will prevent the unit from static charge but any
voltage applied to signal ground will pass through all connectors.
To prevent electric shock, make sure that all devices in the signal
path are grounded properly.
Never connect an amplifier output pin to any other in- or output
connector pin or earth (ground). This might damage the
mainframe or lead to electric shock.
Lay all cables to and from the unit so that they cannot be crushed
by vehicles or other equipment and that no-one can step on them.
Keep dust, moisture, water or other liquids well away from the
unit.
Never operate the unit when it is open.
