It is the customer’s responsibility to make sure

these devices are mounted safely and in compli-

ance with local building codes.

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-

ures 2 and 3

). A junction box is provided for this

purpose. There is a hole provided in the cabinet

bottom-wall for bringing in the AC line. The entry

box contains a standard two-receptacle AC outlet

that serves as a junction for the incoming line and

also provides a convenient AC outlet for running

test equipment. See figure 3 below. Use conduit for

running the wiring into SB II and #14 gauge or

larger conductors.

Backup DC Power

SB II may be run on a DC power source that can

supply 24 to 30 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.

One set changes state when the AC power supply

shuts down for any reason and the unit switches to

operation on the backup DC power system.

The other set of contacts changes state when any

of a number of fault conditions arises within the

electronics such as current drain outside of the

expected operating range in some module.

Route the alarm wires through one of the access holes in the bottom of the box, strip about 3/16” of insulation from each end, loosen the screw terminal, insert and retighten. Use #20 or #22 gauge insulated wire. Use of these terminals is optional. SB II also has a number of status LEDs built-in to individual modules to indicate a fault condition.

It is wise to repeat the procedure listed above for measuring antenna isolation with the signal generator set to frequencies at the passbands edges in order to see if the isolation is remaining relatively constant over the complete width of the passband.

This is the normal display for the signal booster. The system will return to this display from any other display if none of the menu interface buttons are pressed within 2 minutes. The exception is the OLC status display which does require a button press to exit.
