AC Line
Signal Booster II+ is designed to be hard-wired to
100 - 240 single phase AC lines at 50 - 60 Hz.
Bring the AC line into the cabinet through a conduit
opening on the bottom of the enclosure. Connect
the AC line to the terminal strip located behind the
flip-up panel and to the right of the On/Off switches.
Refer to the photo shown in Figure 5. The output
side of the switch is connected to the input of the
power supply assembly. Use conduit for running
the AC wiring into the SB II+ and #14 gauge or
larger conductors.

Backup DC Power
SB II+ may be run on a DC power source that can
supply 20 to 27 volts DC (24 VDC nominal). Screw
terminals are provided for this connection as
shown in figure 5). Bring the DC backup voltage
into the cabinet through a conduit opening on the
bottom of the enclosure. Connect the DC lines to
the terminal strip located behind the flip-up panel
and to the right of the On/Off switches. Use #16 or
#18 gauge wire for this connection.

RF Connections
All RF cabling connections to the booster should
be checked for correctness prior to powering up the
system. N(F) bulkhead connectors are provided on
the bottom of the cabinet for connection to the sig-
nal distribution system. Be sure that the correct
branch of the distribution system is connected to its
corresponding Uplink/Downlink connector or the
system will not work properly. Using high-quality
connectors with gold center pins is advised. Flexi-
ble jumper cables made of high-quality coax are
also acceptable for connecting to rigid cable sec-
tions.

CAUTION:
The maximum RF input
power level for the SBII+ is -20 dBm.
Stronger input signals will cause the
unit to exceed it’s IM specifications.
Static Input signals stronger than -10
dBm may physically damage the unit.
