6 At the DC circuit breaker box, connect the DC power supply.
7 Place the circuit breaker in the ON position and then test the connectorized end of the DC
power cable for proper voltage levels and correct polarity using a volt-ohm-meter.
8 When testing is complete, place the circuit breaker in the OFF position.
9 Remove the dust cap from the AC/DC power port located on the bottom of the enclosure
as shown in Figure 4-7.
4.1.9 Touch-Up Painting
An aerosol container of paint (Cardinal manufacturing part number A-2008-E10559, Gloss
Beige) is available for touching-up nicks and scratches in the factory coat of paint. Lightly
sand the area to be painted and then clean it thoroughly to remove and dirt, dust, or foreign
matter. Shake the paint container until thoroughly mixed and then apply a light coat of paint to
the damaged area. Wait until the paint is dry and apply a second coat if necessary.
4.1.10 Shield Installation (option)
A set of shields is provided with the microBTS as an option (part number DGVC-00000SS2).
The shields primarily reduce the effects of solar loading on the aluminum enclosure. The
shields also prevent accidental contact with surface areas of the enclosure that under extreme
service conditions may become hot enough to cause burns. Install the seven 3/8-inch hex
standoffs as shown in Figure 4-9. Secure the two side shields and the top shield to the standoffs
using the seven 3/8-inch 10-32 TORX drive screws and seven #10 split washers provided. A
T25 TORX drive bit is provided for tightening the screws.

Green/ Yellow Ground
DANGER: While trying to connect the DC power cable to the remote unit DC power port, it is
possible for the positive or negative terminal on the cable connector to contact the ground pin on the
power port. If the DC cable is energized, this will result in a direct short to ground for the DC power.
To avoid possible personal injury and equipment damage, always turn the DC power off before con-
necting the DC power cable to the DC power port.
