UNPACKING AND INSPECTION
4-1.
Uncrate the test stand and set it on a solid, level floor or
a.
foundation, using a suitable fork-lift through the locations pro-
b. Remove all barrier material from the test stand.
c. Inspect the test stand for damage to the motor housing (14, fig
3-1) of the
varidrive, the
gearcase (10, fig 3-1) of the
varidrive,
the blower housing and mounting (4, fig 4-4), the blower duct, and all
front panel meters and switches (fig 2-1 and 2-2).
d. Check to see that all interconnecting cables are in good condi-
tion, and that all wiring is undamaged and secure.
NOTE
All accessories are shipped in the storage compart-
e. Inspect and tighten, as neccesary, all screws, bolts, knobs,
and terminals.
f.
Check the zero setting of all meters (see 2-3.c).
INSTALLATION.
4-2.
a. Power Requirements. A 230/460 volt, 3 phase, 60 Hz, ac power
source is required for operation of the test stand. The test stand
can be operated from a diesel-generator source of power, providing
that the input to the test stand is regulated and maintained at
230/460 volts, 60 Hz. Note the following:
(1) The low voltage starting condition associated with a diesel-
engine generator is compensated for by using a low voltage coil for
starting with a voltage dropping resistor in series with the coil for
running conditions.
(2) If the nominal output voltage of the diesel-engine generator
is lower than 230/460 volts, the power delivered by the output shafts
