6.11.4 Basic connection diagram
Refer to Section 6.1.4 "Installing internal options (OPC-VG1-)" before performing wiring or
connection work.
• Performing connection work in an inappropriate manner may result in electric shock, fire, or other damage.
Qualified electricians should carry out wiring. When touching electrical circuits, for example when performing
connection work after the unit has been energized, shut off the power supply's circuit breaker to prevent
electric shock.
The smoothing capacitor remains charged even when the circuit breaker is shut off and will cause an electric
shock when touched. Verify that the inverter's charge lamp ("CHARGE") has turned off and use a tester or
other instrument to verify that the inverter's DC voltage has fallen to a safe level.
• Do not use products with damaged or missing parts. Doing so may result in bodily injury or damage.
Inappropriate installation or removal of the product may cause damage to the product.

Note: As a rule, shielded wires are earthed.
However, if excessive induced noise from
external sources affects the system, the
effects of such noise can be reduced by
connecting shielded wires to 0 V.
