2 INSPECTION AND INSTALLATION
2.1 VISUAL INSPECTION
Prior to shipment, this instrument was inspected and found to be free of mechanical and
electrical defects. As soon as the unit is unpacked, inspect for any damage that may have
occurred in transit. Verify the following:
A. Check the operation of the front panel controls (knobs should rotate smoothly) .
B. Verify that the circuit breaker latches in the ON and OFF positions.
C. Confirm that there are no dents or scratches on the panel surfaces.
D. Check front panel meters and LEDs for any broken or cracked lenses.
If any damage is found, follow the "Returning Equipment" instructions.
2.2 LOCATION
This instrument is fan cooled. Sufficient space must be allocated so that a free flow of
cooling air can reach the sides of the instrument when it is in operation. Insure that there is
4” (10cm) front and rear as well as 2° (5cm) on each side for adequate air flow. It is also
desirable, although not mandatory, that the unit should be located so as to allow cooling air
to enter through the top cover. Make sure that adjacent equipment does not block air intake
or exhaust openings of the power supply. Air enters at the front panel and is forced out of
the rear panel. This power supply is intended for rack mounting. A conventional 19-inch
rack (or equivalent) that encloses the sides, top and rear must be used.
2.3
ELECTRICAL INSTALLATION
Except for test purposes, this power supply should not be operated with covers
removed. Please refer to safety precautions detailed in Section 1.2. After the
supply has been installed in a location with sufficient space for ventilation, the
appropriate AC input voltage can be applied. The user should ensure that the AC
input wires are of the proper gauge (refer to Table 1.1). Units with IEC connector
require a line cord with the appropriate IEC 380 style connector. The safety ground
wire must be the same gauge as the AC input wires to ensure that it does not open
and create a safety hazard. Load wires to be connected to the POS. and NEG.
output terminals must be of sufficient size to prevent substantial IR voltage drops
between the output terminals and the load.
1.
600W and 1KW
: Units will be factory set for 115 or 230 Vac input. This will be
decided by customer upon ordering and will be indicated on unit upon delivery. Look for
AC input rating on the rear terminal of the power supply received and operate
accordingly.
WARNING
Do not operate a 115 Vac unit at 230 Vac; Unit will be damaged.
