REAR CONTROL PANEL 1A4A4 - Continued.
1.
2.5 kW HEAT STAGE 1 Circuit Breaker 1A4A4CB5
Provides circuit protection for stage 1 electric heater. This circuit is active only when an
external power source is utilized.
2.
3.0 kW HEAT STAGE 2 Circuit Breaker 1A4A4CB6
Provides circuit protection for stage 2 electric heater. This circuit is active only when an
external power source is utilized. The 10 kW Tactical Quiet Generator (TQG) supplied with
CBPS will only support this heat setting when used for supplemental power in internal power
mode.
3.
3.0 kW HEAT STAGE 3 Circuit Breaker 1A4A4CB7
Provides circuit protection for stage 3 electric heater. This circuit is active only when an
external power source is utilized. The 10 kW TQG supplied with CBPS will only support this
heat setting when used for supplemental power in internal power mode.
4.
10.0 kW HEAT STAGE 4 Circuit Breaker 1A4A4CB8
Provides circuit protection for stage 4 electric heater. This circuit is active only when an
external power source is utilized. The 10 kW TQG supplied with CBPS will not support this
heat setting. A 30 kW power source must be used for supplemental power in internal power
mode.
5.
HYDRAULIC PUMP/MOTOR Circuit Breaker 1A4A4CB9
Provides circuit protection for the 7.5 horsepower AC electric motor used to power hydraulic
pump in wheel well. This circuit is active only when an external power source is utilized.
NOTE
All DC circuit breakers (items 6 through 10) are turned on whenever the system is in use,
regardless of the operating mode selected.
6.
OUTLET ASSY Circuit Breaker 1A4A4CB10
Provides circuit protection for receptacle panel electrical outlets located at rear of Lightweight
Multipurpose Shelter (LMS). The Air Beam Shelter (ABS) lights and Nuclear, Biological, and
Chemical (NBC) recirculation filters are powered from these outlets. This circuit receives its
power from ECV electrical system when POWER MODE switch (40) is in INT position and
from 10 kW TQG when POWER MODE switch (40) is in EXT position.
7.
LTG/INTERCOM Circuit Breaker 1A4A4CB4
Provides circuit protection for electrical components associated with lighting and intercom
control system. This circuit receives its power from ECV electrical system when POWER
MODE switch (40) is in INT position and from 10 kW TQG when POWER MODE switch (40)
is in EXT position.
8.
INSTM CONT Circuit Breaker 1A4A4CB3
Provides circuit protection for electrical components associated with engine coolant
temperature and engine oil pressure warning system. This circuit receives its power from ECV
electrical system when POWER MODE switch (40) is in INT position.
9.
NBC/VENT Circuit Breaker 1A4A4CB2
Provides circuit protection for electrical components associated with NBC/ventilation control
system. This circuit receives its power from ECV electrical system when POWER MODE
switch (40) is in INT position and from 10 kW TQG when POWER MODE switch (40) is in
EXT position.
10.
HEAT/COOL Circuit Breaker 1A4A4CB1
Provides circuit protection for electrical components associated with heating and cooling
control system. This circuit receives its power from ECV electrical system when POWER
MODE switch (40) is in INT position and from 10 kW TQG when POWER MODE switch (40)
is in EXT position.
