Then wait for five minutes or more.
3. Remove the front cover.
4. Remove four screws fixing the rear cover of the con-
trol box and slowly open the rear cover.
A. In case of using with 3-phase 200V to 240V
• Changing the changeover connector
Connect to 200V the 100/200V changeover connec-
tor of FLT-T p.c.b.
Side of the control box.
• Connect the crimp style terminal of AC input cord to
the power plug as shown in the figure.
B. In case of using with single phase 100V to 120V
• Changing the changeover connector
Connect to 100V the 100/200V changeover connec-
tor of FLT-T p.c.b.
Side of the control box.
• Connect the crimp style terminal of AC input cord to
the power plug as shown in the figure.
(Caution) Securely perform the insulation treatment
to the red terminal which is not used with
insulation tape or the like. (When the in-
sulation is insufficient, there is a danger
of electric shock or leakage current.)
C. In case of using with single phase 200V to 240V
• Changing the changeover connector
Connect to 200V the 100/200V changeover connec-
tor of FLT-T p.c.b.
Side of the control box.
• Connect the crimp style terminal of AC input cord to
