WARNING
ELECTRIC SHOCK
Before connecting the electrical wires, always verify that the requirements
listed are complied with.
See “Requirements for connecting electrical wires” on page 6.
Never insert sharp objects (small screwdrivers, wires, etc.) into the
connection terminals for electric conductors, and do not touch the terminals.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.
