① Lead the Flexible Cord connected to ELB terminal inside the unit:
2.5 mm², 3 core Flexible Cord.
② Unscrew the Cord Holder and fix the Flexible Cord. Strip the lead
wire (coating). Fasten the life wire (L) and neutral wire (N) to the
ELB (L,N) and earth wire to the Ground Point with 1 N•m (10 kgf.cm)
torque. Fix back the Cord Holder to its position to clamp the
Flexible Cord.

③ Connect wires in correct polarity (L,N).
• Connecting the wires in wrong polarity (L,N) causes an abnormal
condition which may lead to electric leaking, burning and such.
• Before wiring, please check polarity (L,N) with voltage range
of a tester or voltmeter by connecting one terminal of the meter
to earth while the other to one of the
Power-Supply Terminals.
• When the needle of the meter
deflects greatly, the polarity of
the Power-Supply Terminals is 'L'.
