*1. The default settings are given for terminals S3 to S7. For a 3-wire sequence, the default settings are a 3-wire sequence for S5, multi-
step speed setting
1 for S6 and multi-step speed setting 2 for S7.
*2. Do not use this power supply for supplying any external equipment.
*3. When driving a reactive load, such as a relay coil with DC power supply, always insert a flywheel diode as shown in

1. In Fig 4 the wiring of the digital inputs S1 to S7 is shown for the connection of contacts or NPN transis-
tors (0V common and sinking mode). This is the default setting.
For the connection of PNP transistors or for using a 24V external power supply, refer to
2. A DC reactor is an option only for Inverters of 18.5 kW or less. Remove the short circuit bar when con-
necting a DC reactor.
