1.7 Electrical Safety
WARNING!
Avoid contact with an exposed fuel cell stack. Electrical shock can cause personal injury or death.
• Do not touch fuel cell plates or any electrical components at any time. A running fuel cell stack is a
potential electrical hazard that can cause burns or electrical shock.
• Do not wear metallic jewellery – rings, bracelets, watchbands, or necklaces – when you are close to
an exposed fuel cell stack.
• Minimise static discharge. If possible, ground all equipment.
• Minimise conductivity. Avoid contact with surfaces that are in contact with water or gases. Do not
operate or store in wet or damp conditions.
• Never use damaged extension cords.
The stack generates up to 72 VDC (open circuit voltage). This voltage decreases as current is drawn
from the stack. The stack produces 43.2V at maximum power. This voltage is exposed at the output
power connections. These low voltages may constitute a shock hazard and can damage electronic
components if shorted. Therefore, do not touch individual fuel cells, cell voltage monitoring equipment
or electrical components.
WARNING!
Do not touch fuel cells, cell voltage monitoring equipment or electrical components. Electronic
components can also be damaged as the result of static discharge. To minimise this, ground all
equipment in contact with the stack. Never use damaged extension cords. Minimise conductivity by
avoiding surfaces in contact with water; hands and clothes must be dry. Do not operate or store the
stack in wet or damp conditions.
WARNING!
Minimise static discharge. Ground all equipment. Residual reactants within the stack can develop a
charge in a matter of minutes when turned off. A reading of zero volts across the entire stack does not
guarantee that all fuel cells are uncharged.
WARNING!
Always assume that the fuel cell stack is charged. Jewellery (such as rings, necklaces, bracelets and
watches) may concentrate an electric current when it comes into contact with charged components,
or when a shock passes through the human body. Accordingly, no jewellery should be worn near the
stack.
WARNING!
Do not wear jewellery near the stack.
