INSTALLATION
INITIAL INSPECTION :
As soon as the 1315D variable AC/DC source is unpacked,
inspect for any damages that may have occured during
transit. Save all packing material until inspection
is complete. If damage is found, notify the carriers
immediately. Our authorised representative also should be
notified.
PHYSICAL CHECK :
This check should confirm that there are no broken knobs.
The cabinet and panel surfaces should be free of dents.
ELECTRICAL CHECK :
The 1315D variable AC/DC source is shipped ready for
bench operation. It is necessary only to connect the
instrument to a rated input voltage 115V or 230VAC / 60 Hz
/ 5A source of power. To select the correct input voltage
select tap selection switch at the rear panel and it is ready
for operation.
INPUT POWER REQUIREMENTS :
The 1315D variable AC/DC source may be operated
continuously from a 115V or 230V AC / 60 Hz power sourc
with the help of input selector switch at the rear panel.
REPACKING FOR SHIPMENT :
To ensure safe shipment of the 1315D variable AC/DC
source, it is recommended that the package designed
for the instrument be used. The original packing
material is reusable.
