SECTION - 3 INSTALLATION 3.1 3.2 3.3 3.4 3.5 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.

These tests may also be used to verify basic operation when the unit has been restored to normal use after prolonged storage. C25 10µF/50V, ELE C26 0.
c) Turn the voltage and current controls fully counter clockwise. d) Connect a DC ammeter or a shunt-digital voltmeter (DVM) combination across the output terminals using appropriately-gauged wire and hardware. The recommended current ratings for the ammeter or the shunt and the wire must be atleast 5A. The ammeter or shunt-DVM combination must be rated better than 0.5% accuracy.
to the negative terminal), the diode will conduct, shunting current across the output t erminals to the forward voltage drop of the diode. This diode protects the series transistor and the output electrolytic capacitors.
4.7 SECTION 5 PART LIST & SCHEMATICS REMOTE SENSE : Remote sensing is accomplished by connecting the load to remote sensing terminals on the front panel and selecting the remote mode by pressing the "SENSE MODE" push switch. The leads from the sensing (+S and -S) terminals to the load will carry much less current than the load leads and it is not required that these leads be heavy as the load leads. However they must be twisted or shielded to minimize noise pickup.
