26 Watts represents the heat release value for the ECS Controller
equipped with the 113B2 control unit, CP2, and CP3.
144 Watts represents the heat release value for the converter shelf
equipped with two converters.)
4. A Group 1 or Group 2 plant equipped with a Group 7
distribution panel is factory configured for a +21.25 volt
low voltage disconnect threshold. You can change this
threshold to +20.25 volts by adding jumpers J505.1 and
J505.2 on the BCB4 circuit pack (CP5) across pins 2 and 3
of both P505.1 and P505.2.
5. A Group 1 or 2 plant equipped with one rectifier shelf
(Group 4) may not be field upgraded to add a second
rectifier shelf (Group 5). Lucent does not recommend this
upgrade since the plant would have to be shut down in
order to protect the installer from exposure to hazardous
voltages.
6. Circuit breakers are not factory mounted.
7. Specify circuit breaker positions on the distribution panel.
These positions are numbered from left to right.
8. Cable congestion makes circuit breaker position
assignment critical. Start at the bottom of the circuit
breaker panel and expand upwards.
9. The battery bus bars accept direct termination of 4/0 AWG
wire for battery terminations. (See note 29.) Use “H” taps
for larger wire sizes. System ground connection will
accommodate the cable and lug sizes in the table below.
