POWER CONNECTIONS
Superterm CIC1800 / CICP1400UL 18
Step-Down Transformer Connection
The Superterm circuit board is powered from an
internal power supply driven by a separate step-
down transformer. The step-down transformer is
mounted on the bottom ledge of the Superterm
cabinet (see Figure 2, page 5, Superterm
Components).
The Step-Down transformer connects to the
Superterm circuit board through the Power Input
terminal strip (see Figure 8, page 11, Superterm
Circuit Board Layout).
Table 2 lists the connections between the Step-
Down Transformer and the Superterm Power Input
terminal strip. Refer to Figure 9, page 13, while
reading Table 2 for Step Down Transformer to
Superterm Circuit Board connections.
NOTES: If the Superterm is NOT using the
optional Expansion Power Supply, leave the
female Molex connector from the transformer
unconnected.
If the Superterm is equipped with an Expansion
Power Supply, connect the female Molex
connector from the Expansion Power Supply to the
male Molex connector of the Transformer
Assembly (see Figure 9).
Power Input Terminal Strip Jumpers
Pins 1, 2, and 3 of the standard Superterm (with no
Expansion Power Supply) must be jumped
together. Table 3 lists the pin connections on the
Power Input terminal strip that require jumpers.
Refer to Figure 9, page 13 while reading Table 3
for Power Input terminal strip jumper connection.
NOTE: If using an Expansion Power Supply, pin 1
must be open, and pins 2 and 3 must be jumpered
together. Refer to CAUTION on page 13.
Battery Backup Connection
During power interruptions, the Superterm
continues operating for a maximum of 4 hours via
an on-board 7A-hour back-up battery (standard
version) or a 12A-hour back-up battery (expanded
version).
Table 4 lists the connections from the Battery
Backup to the Superterm Power Input terminal
strip. Refer to Figure 9, page 13, while reading
Table 3 for Battery Backup to Superterm Circuit
Board connections.
WARNING
Do NOT connect the Backup Battery or provide
AC source voltage to the Superterm until all
accessory cabling is completed.
