ommend consulting local building inspectors, engi-
neering consultants or architects for advice on how
to properly mount objects of this type, size and

It is the customer’s responsibility to make sure
these
devices are mounted safely and in compli-

CONNECTIONS
All cabling connections to the booster should be
made and checked for correctness prior to power-
ing up the system.
AC Line
Signal Booster II is designed to be hard-wired to
110 single phase AC lines at 50 - 60 Hz (see
Fig-
ure 3
). An AC line filter is provided for this purpose.
There is a hole provided in the cabinet bottom-wall
for bringing in the AC line. Fasten quick connect
plugs to each wire of the incoming AC line, then
connect the ground wire, neutral wire, and hot wire
to the respective pins on the top of the AC line filter
assembly. The output of the AC line filter is wired
into the switch box which also contains a dual con-
venience outlet for running test equipment. Use
conduit for running the AC line into the SB II cabi-
net and use #14 gauge or larger conductors.
Backup DC Power
SB II may be run on a DC power source that can
supply 24 to 27 volts DC at 2.5 amps. Screw termi-
nals are provided for this purpose (see figure 2).
This line should be equipped with a fast-acting 3
Amp fuse. Use #16 or #18 gauge wire for this con-
nection.
The power system in SB II automatically switches
to this backup DC input when the AC supply fails
for any reason including a power outage or inten-
tional disconnection.
It is not necessary that this connection be made for
normal operation on the AC line.
Alarm Terminals (Form-C contacts)
Two sets of contacts are provided to monitor the
general operating condition of SB II and are
intended for connection to a supervisory system.
See figure 2.
