the
wire to the connector. The barrel on each connector that is closest to the center of the
fuse
panel (barrel with a cap over it) is not used or accessed. The wire is inserted into the
connector
and the set screw is tightened down, compressing the wire. The set screw barrel
connectors
can accept up to #6 AWG copper wire.
1.5 Output Voltage
The
output voltage will be the same voltage as the applied input voltage when the fuse does not fail.
1.6 Output Connectors
Each
output circuit has two connectors through which the output power is accessed for
connection
to telecommunications equipment. The following types of output connectors are
available:
• Screw-down
barrier terminal strip: Eight terminals with 6-32 screws are mounted in two
barrier
type terminal strips per bus (one strip for input and one strip for return). The
terminals
are on 0.375 inch (9.525 mm) centers with a maximum distance between
barriers
(maximum connecting terminal width) of 0.325 inch (8.255 mm). Terminals can
accept
#12 to #22 AWG copper wire with crimp-on spade lug or ring connectors or wires
with
the insulation stripped back.
• Set
screw barrel terminal strip: Eight barrel terminals are mounted in two set screw barrel
terminal
strips per bus (one strip for input and one strip for return). The terminals are on
0.197
inch (5.004 mm) centers. Terminals can accept #12 to #26 AWG copper wire with
insulation
stripped back.
1.7 Chassis Ground Connection
Two
#10 studs mounted on 0.625 inch (15.875 mm) centers are provided for grounding the fuse
panel
chassis. This chassis ground connection can be used to attach a separate grounding
conductor
when mounting the fuse panel in non-grounded or non-conducting material or when
required
by local practice. The studs can accommodate 2-hole lugs and up to #6 AWG wire.
Two
crimp ring lug terminals for use with #10 AWG wire are enclosed with the fuse panel. The
fuse
panel can be properly grounded using only one grounding stud.
1.8 Fuses
The
fuse panel accommodates industry standard type 70 fuses with values from 0.02 Amp to
10.0
Amps in any fuse position within the maximum capacity of the bus (total fuse load cannot
exceed
bus capacity). The maximum fuse value that can be used in each fuse position is 10.0
Amps
which is marked on the front panel.
The
type 70 fuse contains a colored indicator that designates the fuse value. When the fuse
blows,
the indicator extends out of the fuse to indicate that the fuse has blown. Fuse panels are
shipped
without fuses installed. Standard type 70 fuses are available from ADC.
