6.4
SHOCK
The rectifier in its shipping container, withstands shock developed when one edge of the container is
dropped six (6) inches while the opposite edge is resting on the ground, or it is dropped two (2) inches
on any surface without any physical damage or degradation of the electrical performance.
6.5
VIBRATION
The rectifier in its shipping container withstands vibration encountered in shipping without physical
damage or degradation of the electrical performance.
6.6
ALTITUDE
This rectifier is capable of operation at altitudes to 10,000 feet at an ambient temperature of
up to +40 degrees C.
6.7
VENTILATION
The unit should be mounted so that ventilating openings are not blocked and air entering the cabinet
does not exceed 122 degrees F.
6.8
AUDIBLE NOISE
Audible noise is not greater than 65 DBA measured at 5 feet from any surface on the unit enclosure.
7.0 INSTALLATION INFORMATION
7.1
MINIMUM WIRE SIZES
Table 2 lists the a.c. input and the D.C. output minimum wire size requirements. At distances exceeding
10 feet, the d.c. wire size should be chosen to keep the voltage difference between the units d.c.
output terminals and the battery at less than 1/2 volt when the unit is fully loaded. See Section 7.6 for
“POWER CABLING FORMULAS”. The total loop length is twice the distance from the wiring point to the
unit.
7.2
WIRE SIZE TABLE
(Refer to TABLE 2)
7.3
NATIONAL CODES
These wire sizes are based on those recommended in the National Electric Code Table 310-16 for copper
wire at 75 degrees C conductor temperature operating in an ambient of 30 degrees C. For higher
operating temperatures refer to the derating factors in the National Electric Code Table 310-16.
7.4
FIELD GROUND TERMINAL
This terminal should be connected to an earth ground. The size of the conductor is based on National
Electric Code Table 250-95 for copper wire at 75 degrees C. (See Table #3 for recommended wire sizes.)
7.5
MOUNTING
Install the rectifier so that the flow of air through the ventilators is not obstructed.
