6.8.4 Connection
Refer to 6.1.4 "Installing internal options (OPC-VG1-)", and then perform wiring and connecting wires.
This option should be mounted at port B (CN2).
・ Incorrect handling in connecting job could cause an accident such as electric shock or fire. Qualified
electricians should carry out connecting wires. If connecting wires, for example, after the power is turned ON
requires any touching of an electric circuit, turn OFF (open) the breaker on the power supply side to prevent
electric shock.
・ Since the smoothing condenser has been charged although the breaker is turned OFF (open), touching an
electric circuit causes an electric shock. Confirm, with a tester, etc., that the charge lamp (CHARGE) of the
inverter is turned OFF and the DC voltage of the inverter has been reduced to the safety voltage.
・ Do not use the product that is damaged or lacking parts. Doing so could cause injury or damage.
・ Incorrect handling in installation/removal could result in a broken produce.
