G
REEN
light indicates internal voltage is within specified range. A D

LED may indicate PDU
malfunction or short circuits present at more than two outputs.

G
REEN
light indicates voltage and current is within normal range for each output.
R
ED
light indicates a fault condition, i.e., current is outside normal range (including when the output
is disabled). The R
ED
light is latched and the indication will persist until reset by the user.
A D
ARK
LED indicates current monitoring is D
ISABLED
.

The Alarm Cable is connected here and routed to the BTS EAI. A summary A
LARM
state is indicated
if the PDU or any output is in a fault condition. The indication is automatically reset upon clearing the
fault condition. With no supply power to the PDU, the default indication is the A
LARM
state. An
insulated relay is used as the Alarm Interface.

current monitoring for each output. Flip up to D
ISABLE
. When D
ISABLED
, the
associated LED is D
ARK
, a latched R
ED
light is reset, and the Alarm Interface ignores the output.

Flip up to E
NABLE
and turn on voltage for each output. Flip down to D
ISABLE
. When D
ISABLED
, no
voltage is present on the output. If current monitoring is E
NABLED
, the LED and Alarm Interface
indicate a fault condition.

The Bias Tee Harness is connected here and routed to up to six bias tees. Each of the six outputs is
individually monitored and protected. Nominal voltage is +12 VDC.
The rear panel control is illustrated in Figure 6.
