DANGER: RISK OF ELECTROCUTION
•
Turn OFF all power supply before
removing the switch box cover,
connecting electrical wiring or touching
electrical parts.
•
Disconnect the power supply for more
than 1 minute and measure the voltage
at the terminals of main circuit capacitors
or electrical components before
servicing. The voltage MUST be less
than 50 V DC before you touch electrical
components. For the location of the
terminals, consult the wiring diagram.
•
Do NOT touch electrical components
with wet hands.
•
Do NOT leave the unit unattended when
the service cover is removed.
WARNING
If NOT factory installed, a main switch or
other means for disconnection, having a
contact separation in all poles providing
full disconnection under overvoltage
category III condition, shall be installed in
the fixed wiring
.
WARNING
•
ONLY use copper wires.
•
Make sure the field wiring complies with
the applicable legislation.
•
All field wiring must be performed in
accordance with the wiring diagram
provided with the unit.
•
NEVER squeeze bundled cables and
make sure they do not come into contact
with the piping or sharp edges. Make
sure no external pressure is applied to
the terminal connections.
•
Make sure to install earth wiring. Do NOT
earth the unit to a utility pipe, surge
absorber, or telephone earth. Incomplete
earth may cause electrical shock.
•
Make sure to use a dedicated power
circuit. NEVER use a power supply
shared by another appliance.
•
Make sure to install the required fuses or
circuit breakers;
•
Make sure to install an earth leakage
protector. Failure to do so may cause
electric shock or fire.
•
When installing the earth leakage
protector, make sure it is compatible with
the inverter (resistant to high frequency
electric noise) to avoid unnecessary
opening of the earth leakage protector.
NOTICE
Precautions when laying power wiring:
•
Do not connect wiring of different
thicknesses to the power terminal block
(slack in the power wiring may cause
abnormal heat).
•
When connecting wiring which is the
same thickness, do as shown in the
figure below.
•
For wiring, use the designated power
wire and connect firmly, then secure to
prevent outside pressure from being
exerted on the terminal board.
•
Use an appropriate screwdriver for
tightening the terminal screws. A
screwdriver with a small head will
damage the head and make proper
tightening impossible.
•
Over-tightening the terminal screws may
break them.
Install power cables at least 1 metre away from
televisions or radios to prevent interference.
Depending on the radio waves, a distance of 1
metre may not be sufficient.
WARNING
•
After finishing the electrical work, confirm
that each electrical component and
terminal inside the electrical components
box is connected securely.
•
Make sure all covers are closed before
starting the unit.
