control box, do not let any liquid spill into the
box, and do not touch the components in the
box with wet hands.
Cut off power supply more than 10 minutes
prior to access the electrical parts. Measure
the voltage of the main circuit capacitor or
electrical component terminals to make sure
the voltage is less than 36 V before you touch
any
circuit
component.
connections and wiring on the nameplate for
the master circuit terminals and connections.
The installation must be completed by
professionals, and must comply with local
laws and regulations.
Make sure the unit is earthed, and the
earthing must conform to the local law.
Use only copper core wires for installation.
Wiring must be carried out in accordance with
what is stated in the nameplate.
The unit does not include a safety switch
device. Make sure a safety switch device that
can completely disconnect all polarities is
included in the installation, and that the
safety
device
can
disconnected when there is excessive
voltage (such as during a lightning strike).
Make sure the wiring ends are not subjected
to any external force. Do not pull or squeeze
the cables and wires. At the same time, make
sure the wiring ends are not in contact with
the piping or sharp edges of the sheet metal.
Do not connect the earth wire to public pipes,
telephone earth wires, surge absorbers and
other places that are not designed for
earthing. A gentle reminder that improper
earthing may cause electric shock.
Use a dedicated power supply cord for the
unit. Do not share the same power source
with other equipment.
A fuse or circuit breaker must be installed,
and these must conform to the local law.
Make sure an electric leakage protection
device is installed to prevent electric shocks
or fire. The model specifications and
characteristics (anti high-frequency noise
characteristics)
of
the
protection device are compatible with the unit
to prevent frequent tripping.
Make sure a lightning rod is installed if the
unit is placed on the roof or other places that
can be easily struck by lightning.
