·Only terminals with SELV and/or which comply with ETS 300047 may be connected to the PABX
system. This regulation is fulfilled when approved terminal devices are used as intended.
·The distance between the plug-in power supply unit and the PABX and to the ISDN connection
should not exceed 1. 5 meters so that standard connecting lines can be used.
·The PABX is operated with 230 V AC using the plug-in power supply unit. Please ensure that the
electrical outlet (grounding outlet) for the PABX (and for additional devices where required) is
installed such that it is freely accessible at all times and that it is installed by a qualified electrician
to prevent any risks of personal or material injury/damage! Where at all possible, provide a sepa-
rate power circuit for the 230 V ac connection of your PABX system; This protects your PABX
from short-circuits that may occur in other in-house equipment.
·We recommend installing an overload protection to protect your PABX against surge that can so-
metimes occur during thunderstorms. For further information please contact your local
electrician.
·To prevent mutual interference, do not install your PABX system in the immediate vicinity of
electronic devices such as stereo equipment, electronic office equipment or microwave units.
Avoid installing your PABX near sources of excessive heat, e.g. radiators or in rooms with exces-
sive humidity. The ambient temperature at the location where the system is operated must be
between 5 to 176° C.
