Operation
CAUTION
Risk of injury from hydrogen ignition
During operation, small amounts of hydrogen are continuously
released into the atmosphere. Escaping hydrogen may ignite when
in proximity to an ignition source.
Keep product away from ignition sources. Ensure ventilation in
accordance with the general safety instructions.
CAUTION
Risk of injury from hydrogen ignition
Damaged tubes or leaking connections may cause hydrogen to
escape. Hydrogen and hydrogen-air mixtures may ignite when in
proximity to an ignition source.
Check tubes and connections for damage before each setup and
before each use.
CAUTION
Risk of injury from hot surfaces
The protection diode on the electrolyzer becomes very hot in case of
incorrect polarity. Touching the protection diode may cause injuries.
Before starting up, ensure correct polarity of the connecting cables and
the electrical connections (red = “+”, black = “-”).
Do not touch the protection diode.
CAUTION
Risk of injury from hot surfaces
The surface of solar modules may become very hot during operation.
Touching the surface of solar modules may cause injuries.
Do not touch the surface of solar modules during operation.
Do not touch the surface of solar modules even after operation until they
have cooled down to below 60 °C.
