INSTALLATION
INITIAL INSPECTION : As soon as the power supply
unit is unpacked inspect for any damage that may have
occured during transit. Save all packing material until in-
spection is completed. If any damage is found, notify the
carriers immediately. Our authorised representatives should
also be notified.
PHYSICAL CHECK : This check should confirm that
there are no broken knobs or connectors, that the cabinet
and panel surfaces are free of dents and scratches and
the meters are not scratched and cracked.
ELECTRICAL CHECK : The power supply unit should
be checked against electrical specifications.An in-cabinet
performance check will verify proper operation.
INSTALLATION DATA : The power supply unit is shipped
ready for bench operation. It is necessary only to connect
the unit to a rated source of power and it is ready for opera-
tion.
LOCATION : The power supply unit is naturally
cooled.Sufficient space should be kept around the unit while
in operation, so that heat sinks do not remain in confined
space or close to another heating source.The ambient tem-
perature of the area around the unit should be less than
40°C.
INPUT POWER REQUIREMENTS : The power supply
unit may be operated continuously from input voltage of 115V
/ 230V 47-63Hz power source with selectable Switch.
REPACKAGING FOR SHIPMENT : To ensure safe ship-
ment of the power supply unit, it is recommended that the
package designed for the unit be used. The original pack-
aging material is reusable. Be sure to attach a tag to the
unit specifying the owner, and the fault observed with a brief
description.
REMOVING COVER : The top cover is retained in place
by 6 self tapping screws & two handle mounting screws.
To remove cover, proceed as follows :
a) Remove the handle mounting screws.
b) Remove the self tapping screws on sides.
c) Lift the cover from rear side, slide backwards & pull.
