Electrical safety

You must ground the generator before you install the controller or do maintenance work. Failure to ground the generator
can result in injury or death.
Generators produce high electrical voltages. Do not touch terminals, bare wires, and while the generator and related
equipment are in operation. If you touch the generator, it can give you an electrical shock and result in death. Do not change
the interlocks.
Use the correct size for wires that are used for electrical connections and wirings. This is to make sure that the generator
can operate at the maximum electrical current.
1.4.4

Safety during installation and operation

Before you install the controller, make sure that all power voltage supplies are positively turned off at the source. Remove
the panel fuse to prevent accidental start of the generator. Disconnect the battery cables for the generator from the
negative battery terminal first. This is shown with a NEGATIVE, NEG, or (–). Reconnect the negative cable last. If not, this
can give you an electrical shock and possibly kill you.
Remove the electric power supply before you remove the controller or touch other electrical part. High voltage can cause
injury or death.
With floors of metal or concrete, use rubber insulation mats placed on wooden platforms, when you do work near the
generator or other electrical equipment. Make sure you wear dry clothes and shoes, and that your hands and feet are dry
when you operate electric devices or work with wires. Do not wear jewellery. Jewellery can cause a short circuit, which can
result in shock or burning.
If an accident caused by electric shock occurs, stop the electrical power source immediately. If this is not possible, use a
non-conducting object (for example a rope or a wooden stick) to remove the person with the injuries from the live
conductor. Do not touch the person with injuries. If the person with injuries is unconscious, use first aid and get medical
help immediately.
