Safety Information
Safety of Mains Operated Equipment
This equipment has been designed to meet the safety regulations currently advised
in the country of purchase and it conforms to the safety regulations specied by
use of the CE Mark.
Warning : There are no user serviceable parts inside the equipment. If you should ever
need to look inside the unit, always disconnect the mains supply before removing the
equipment covers.
Warning: The DHY-03 line socket should only be connected with apparatus
complying with BS6301, and the connection to the network must not be hard wired
Interconnection directly or indirectly with equipment ports marked in accordance with
BS6301 to unmarked ports may produce hazardous conditions on the network and
advice should be obtained from a competent engineer before such a connection is made.
Warning: This apparatus must be earthed by means of the earth connector on the rear
panel, and the connection to the telecommunications network should be removed
before disconnecting the earth. Disconnection of this earth connection may render the
equipment unsafe, with a consequential possible electrical shock hazard from exposed
metallic parts.
Warning: The barriered ports ‘LINE’and ‘HANDSET’ must not be connected directly
or indirectly to the un-barriered ports, ‘MIC/LINE INPUT’, ‘OUTPUT’, ‘CONFERENCING’,
‘REMOTES’ or ‘RS-232’.
Voltage Setting Checks
The integral power supply is designed to accept a universal input of 85 to 264 VAC mains
input voltage. The safety specication of your DHY-03 complies with local requirements and
must be earthed through the mains connector.
Fuse Rating
The DHY-03 is supplied with a single fuse in the live conducting path of the mains power
input. For reasons of safety it is important that the correct rating and type of fuse is
used. Incorrectly rated fuses could present a possible re hazard, under equipment fault
conditions. The fuse rating for DHY-03 is:
230 or 115 V operation - 1A 5 x 20mm SB
The active fuse is tted on the outside rear panel of the unit.
