Work procedure
REQUIREMENT
Put on gloves during working; otherwise
an injury may be caused by parts, etc.
1) Stop operation, and then turn off switch
of the breaker.
2) Take off screws (3 positions) of the
terminal block installation board.
3) Take off the fixing screws of each part,
and then remove the cables. ∗
∗ 7. Cautions when removing the electro-
lytic condenser
1) As the natural discharge by the electro-
lytic condenser may be unavailable and
voltage may remain in some cases due
to trouble conditions, be sure to perform
discharge of the condenser.
2) Using resistance for discharge (100Ω/
40W or equivalent) or (plug of) the
soldering iron, make continuity and
discharge between (+) and (–) poles.
(This electrolytic condenser has a large
capacity. Therefore it is dangerous to
make discharge by shortening between
(+) and (–) poles because big sparks
generate.)
Reactor, transformer, and electrolytic
condenser are stored at the rear side
of the terminal block.
