INSTALLATION
2.1
GENERAL
After unpacking, perform initial inspections and preliminary electrical check pro
cedures to assure that the unit is in good working order. If it is determined
that the unit is damaged, the carrier should be notified immediately. Repair
problems should be directed to the nearest Sorensen representative, or to the
factory.
2. 2
INITIAL INSPECTION
Proceed as follows to inspect for damage incurred during shipment:
1.
Inspect panel and chassis for scratches, dents and chips.
2.
Turn front panel voltage and current controls from stop to stop. Ro
tation should be smooth through a 300 degree rotation.
3 . Check meter faces for cracked or broken windows. Check each meter
pointer for zero indication. If necessary, use adjust screw to bring
indicator to zero.
4.
Look for cracked or broken lenses on indicating lights.
5.
Alternate power switch between ON and OFF. Action should be both
positive and audible. Return switch to OFF position.
6.
Remove rear cover, and check terminal board. Make sure that links
are firmly in place across terminals 3-4, 5-6, 7-8. Check the fuse.
7.
Remove top cover retaining screws. Inspect components and printed
circuit board for damage.
2. 3
ELECTRICAL INSTALLATION
Standard units are shipped ready for use with nominal 115 Vac input, but may be
factory or field modified to operate from a nominal 208, 220 or 230 volt input.
(Ml, M2, M3 options respectively).
2.3.1
Input Power Cord
The input power cord terminates externally in a three prong polarized plug. The
unit chassis is wired to the plug through the line cord, and therefore, the insert
ion of the plug into a compatible receptacle, hooked up to a grounded input, will
automatically ground the unit. If a grounded input is not available, use an adapt
er, making sure that the adapters external lead is well grounded.
