ECU Power Connector
The ECU power connectors are located to the right of the ECU.
The ECU power connectors are pre-connected at the factory. These connections should only be temporarily broken and made during
a service event.

Thermal Components and ECU Operation
15.2.1
Primary Equipment Compartment
The primary equipment compartment contains a heat exchanger to cool the compartment.
Primary Equipment Compartment Heat Exchanger Thermal Components
The HX is a closed loop cooling unit with two (2) fans in the internal loop and two (2) fans in the external loop. The same fans
(152224) are used in the internal and external loop.
The inner and outer loop fans operate independently of each other. The use of multiple fans provides redundancy and the failure of
any fan will result in a small but acceptable reduction in the thermal performance. The HX fans (internal and external loops) are
turned off if the equipment compartment door alarm switch is activated.
ECU Control of the Primary Equipment Compartment Thermal Components
The enclosure has a typical ambient operating temperature range of -40
°
C (-40
°
F) to +46
°
C (+115
°
F). The range of operating
temperature for the equipment to be housed in the enclosure is -40
°
C (-40
°
F) to +65
°
C (+149
°
F). The purpose of the heat
exchanger is to remove heat dissipated from equipment while maintaining equipment inlet air temperature. By controlling enclosure
air temperature, the ECU maximizes electronic equipment life. In addition, the ECU limits acoustic noise by reducing fan speeds when
possible.
NOTE!
The fan logic is built around equipment designed for operation at 65 °C. Equipment rated to lower than a 65 °C
upper limit may still be deployed within the enclosure with careful component placement. Alternatively, the fan logic may be
changed -- consult Vertiv Engineering for more details.
Primary Equipment Compartment Temperature Sensors
The primary equipment compartment thermistor determines the Cabinet Air Temperature (T
Cab
).
15.2.2
Battery Boxes
The enclosure contains two (2) battery boxes. The top battery box may be removed in the field.
NOTE!
The battery boxes are nominally sealed except for required hydrogen safety vents.

ECU User Interface
15.3.1
Initial Start-Up Sequence
When power is first applied to the ECU, the ECU goes through the following Start-Up sequence.
Start-Up Sequence
Product Code # and Firmware Code (Revision) # displays.
All fans run at full speed for approximately 30 seconds to detect any fault conditions, then normal operation resumes.
UP displays if everything is operating as expected.
or
Continuous cycle of error codes if any faults detected.
