„ Sinking/Sourcing Mode (NPN/PNP Selection)
The input terminal logic can be switched over between sinking mode (0-V common, NPN) and sourcing mode
(+24V common, PNP) by using the jumper CN5. An external power supply is also supported, providing more
freedom in signal input methods.
Table 3 Sinking/Sourcing Mode and Input Signals
„ For Meeting UL Standard
1. Installation Site: Install the Inverter in a pollution degree 2 environment or equivalent.
2. Specification of Closed-Loop Connector: The closed-loop connectors must be installed on conductors
before installing to terminal blocks. Use JST or equivalent closed-loop connectors shown below.
IMPORTANT
1. In Fig 4 the wiring of the digital inputs S1 to S7 and BB, BB1 is shown for the connection of contacts or NPN
transistors (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
Table 3 .
2. A DC reactor is an option only for Inverters of 18.5 kW or less. Remove the short circuit bar when connecting a
DC reactor.
