CAUTION:
THE EQUIPMENT IS FACTORY SET FOR 220 V OPERATING VOLTAGE.
BEFORE SWITCHING ON THIS INSTRUMENT, SET THE VOLTAGE
SELECTOR TO THE PROPER POSITION AND BE SURE THAT THE FUSE
VALUE IS ACCORDING TO THE MAINS VOLTAGE.
FUSE TYPE SHOULD BE: 5 x 20 mm., 250 V.
0.5 A F FOR 220, 230 and 240 V
1 A F FOR 110 and 125 V
AVOIDING THIS DIRECTIONS COULD DAMAGE THE EQUIPMENT
3.2 Grounding
In order to guarantee safe operation of the GV-698, a suitable connector is
provided on the rear panel for connection to GROUND (Mains Connector [35]).
ATTENTION
Any equipment manufactured with a power supply connected to the chassis
and which is to be connected to the GV-698 must be supplied with an
adequate isolating transformer. Non-observance of this norm may cause
damage to the instrument and/or produce damage to the operator.
3.3 Installation and start-up
The equipment is prepared for use as desk–top equipment.
After having selected the power supply voltage, the equipment may be
connected to the mains and switched on by activating the mains switch [1].
The equipment's highest level of performance is obtained at about 10 minutes
after switching on. This period stabilizes the components sensitive to the thermal
gradient.
ATTENTION
For correct operation of the GV-698, ensure, when connecting the equipment
to an external instrument, that the impedances are correctly matched (see item
1.2 of specifications), otherwise incorrect operation may result.
E.g.: in the case of connection to a TV with a balanced R.F. input of 300
Ω
impedance, an impedance adaptor model A-75/300 GV or similar should be
used.
