line voltage. The maximum power draw is 40 W.
Fuse
The secondary supply voltages are electronically protected against overload or short cir-
cuit. The primary line voltage side is protected by a fuse located on the power supply unit.
The fuse rating covers the full voltage range. Consequently there is no need for the user to
replace the fuse under any operating conditions, nor is it accessible from the outside.
Caution: If this fuse is blown, it is likely that the power supply is badly dam-
aged. Do not replace the fuse. Send the GSG unit to your local Service
Center.
DANGER! — Removing the cover for repair, maintenance and adjustment
must be done by qualified and trained personnel only, who are fully aware of
the hazards involved.
The warranty commitments are rendered void if unauthorized access to the interior of the
instrument has taken place during the warranty period.
Grounding
Grounding faults in the line voltage supply will make any instrument connected to it dan-
gerous. Before connecting any unit to the power line, you must make sure that the pro-
tective ground functions correctly. Only then can a unit be connected to the power line
and only by using a three-wire line cord. No other method of grounding is permitted. Exten-
sion cords must always have a protective ground conductor.
Caution: If a unit is moved from a cold to a warm environment, con-
densation may cause a shock hazard. Ensure, therefore, that the grounding
requirements are strictly met.
DANGER! — Never interrupt the grounding cord. Any interruption of the
protective ground connection inside or outside the instrument or dis-
connection of the protective ground terminal is likely to make the instru-
ment dangerous.
