SECTION III
PREPARATION FOR USE AND RESHIPMENT
3-1. Unpacking Equipment.
The units should be handled and unpacked with care. Inspect
outer cartons for evidence of damage during shipment.
Claims for damage in shipment
must be filed promptly with the transportation company involved
. No internal packaging or
bracing is used for shipments and the units should not rattle when being unpacked.
3-2. Pre-installation Inspection.
Conduct a thorough inspection of the units, paying particular
attention to the following items:
•
Screws in place and tight.
•
All panels and grills free of dents and scratches.
•
AC input receptacle visually OK.
•
Interlock terminal strip visually OK.
•
RF connector visually OK.
While inspecting RF connector, measure DC resistance of the unit by reading from the center
conductor to the outer conductor. Compare this reading to that on the specification sheet at
the end of this manual. Reading should be
±
1 ohm. If not, consult factory.
3-3. Pre-installation Tests.
Prior to installation, connect the load to AC Mains power for the
following tests:
a.
Read data plate on lower rear panel of resistor enclosure and connect to a suitable
source of AC power.
b.
Turn main switch on and check for quiet blower operation.
c.
Connect an ohmmeter or a battery operated test lamp across the normally closed
terminal pair on the interlock terminal board.
d.
Turn the main power switch off, observing the indicator (ohmmeter or test lamp).
It should remain as it was.
e.
Now disconnect the AC power from the unit. The indicator should change state
(terminals open).
3-4.
Installation.
The Model 6715D must be installed in a location convenient for servicing.
Consideration should be given to adequate accessibility for maintenance and unit
replacement. No attempt is made in this handbook to present complete installation
instructions, since physical differences in plant will determine the installation procedure.
General guidelines are outlined in subsequent paragraphs.
