2 General safety precautions
INFORMATION
R290 is denser than air, so in open air it sinks to floor level.
2.2.3 Electrical
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 10 minutes,
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
can touch electrical components. For the location of the
terminals, see the wiring diagram.
▪ Do NOT touch electrical components with wet hands.
▪ Do NOT leave the unit unattended when the service
cover is removed.
WARNING
A magneto thermal circuit breaker, having a contact
separation in all poles providing full disconnection under
overvoltage category III condition, MUST be installed in the
fixed wiring. In case of multiple units each unit must have
its own circuit breaker.
Note that this magneto thermal circuit breaker should not
be used to turn the unit on and off under normal operating
conditions. For that, one should use the controller.
WARNING
▪ ONLY use copper wires.
▪ Make sure all the wiring work complies with the
applicable legislation.
▪ All field wiring MUST be performed in accordance with
the wiring diagram supplied with the product.
▪ NEVER squeeze bundled cables and make sure they
do NOT come in contact with the piping and 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 magneto thermal
circuit breakers. In case of multiple units each unit must
have its own circuit breaker.
▪ Make sure to install an earth leakage protector. Failure
to do so may cause electrical shock or fire. In case of
multiple units each unit must have its own earth
leakage protector.
▪ 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.

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 up the
unit.
WARNING
Never touch a person receiving an electrical shock, or you
could suffer one too. Do not touch the person until you are
sure power is turned off.
Electrical shocks always
attention, even if the victim seems to be fine afterwards.
CAUTION
▪ When connecting the power supply: connect the earth
cable first, before
connections.
▪ When disconnecting the power supply: disconnect the
current-carrying cables first, before separating the earth
connection.
▪ The length of the conductors between the power supply
stress relief and the terminal block itself MUST be as
such that the current-carrying wires are tautened before
the earth wire is in case the power supply is pulled
loose from the stress relief.
DANGER
Tripping over loose wiring can tear it loose and cause
electrocution and fire.
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 above.
▪ For wiring, use the designated power wire and connect
firmly, then secure to prevent outside pressure 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 meter away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
1 meter may NOT be sufficient.
