7. Hydrogen sensor

(Optional)

It triggers at 25% of LFL, which is 1% hydrogen
concentration.

NOTE: This sensor has a delayed respond (for
about 15 seconds).

5. SCU switch

It is to turn the SCU on/o

ﬀ

. For SCU, Please refer to

Terminology.

It is the connector which connect startup ba ery to
the controller

8. Start up battery connector

6. LCD display

It displays the system status, current, voltage, temperature
etc.
Please refer to trouble shooting section for more details

Power supply for hydrogen sensor
Please attached this wire to your on-board battery (12V) to
power the hydrogen sensor.
