2-3 Connection
Remove the surface cover to connect the termi-
nal blocks. Correctl
y
connect them accordin
g
to
the followin
g
procedures.
2-3-1 Basic connection
1. Alwa
y
s connect the power to the main power
suppl
y
input terminal of the inverter. If it is
connected to another terminal, the inverter
will be dama
g
ed (see Fi
g
ure 2-3-1).
2. Alwa
y
s
g
round the
g
round terminal to prevent
disasters such as fire and electric shock and
to minimize noise.
3. Use a reliable crimp terminal for connection
between a terminal and wire.
4. After terminatin
g
the connection (wirin
g
),
check the followin
g
items:
a. Whether the connection is correct
b. Whether all necessar
y
connections have
been made
c. Whether there is a short-circuit or
g
round
fault between terminals and wires
5. Connection modification after power-on
The smoothin
g
capacitor in the direct current
part of the main circuit cannot be dischar
g
ed
quickl
y
after the power is turned off. Use a
multimeter to check that the volta
g
e of the di-
rect current (DC) is reduced to the safet
y
ran
g
e (25V DC or less) after the char
g
e lamp
g
oes off to avoid dan
g
er. Check that the volt-
a
g
e is zero before short-circuitin
g
a circuit be-
cause the residual volta
g
e (electric char
g
e)
ma
y
cause sparks.
CAUTION
Do not allow forei
g
n matter such as
lint, paper dust, small chips of wood or
metal, and dust to enter the inverter or
adhere to the heat sink.
Otherwise, a disaster such as burnin
g
could occur.
WARNING
1. Alwa
y
s connect the
g
round wire.
Otherwise electric shock and fire could
occur.
2. Ensure that a licensed specialist performs
the wirin
g
work.
3. Check before startin
g
the wirin
g
that the
power is off.
Otherwise electric shock could occur.
