INSTALLATION
3.1
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 inspection is complete. If any
damage is found, notify the carriers immediately. Our
authorised representatives should also be notified.
3.2
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.
3.3
ELECTRICAL CHECK :
The power supply unit should be checked against its
electrical specifications.
3.4
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 operation.
3.5
LOCATION :
The power supply unit is naturally cooled. Sufficient space
should be kept around the unit while in operation, so that
heatsinks do not remain in confined space or close to
another heating source. The ambient temperature of the
area around the unit should be less than 40°C.
3.6
INPUT POWER REQUIREMENTS :
The power supply unit may be operated continuously from
a source of 115V or 230V AC with 10A Source.
3.7
REPACKAGING FOR SHIPMENT :
To ensure safe shipment of the power supply unit, the
package designed for the unit be reused. Attach a tag to
the unit specifying the owner, and a brief description of
the fault observed.
