Input/output terminal A-contact/B-contact switchable by making a selection from the programmable I/O
logic switching terminal function menu. (*1), (*2) (Default setting: A-contact)
Sink/source Negative common (CC) and positive common (P24) of control terminal are switchable to
switching each other. (On shipment, negative common [CC] is selected as default setting.)

RS232C, TOSLINE-F10M and TOSLINE-S20 are optional. DeviceNet and ProfiBus
are on the drawing board.

(*1): The 16 contact-input terminals (8 of which are optional) are programmable. For each of them, a signal
can be selected from among 136 signals.
(*2): For each programmable ON/OFF output terminal, a signal can be selected from among 120 signals.
(*3): For each programmable analog output terminal, a signal can be selected from among 32 signals.
(*4): When the cover is removed, the unit must be placed in the panel to prevent the charger from being
exposed. For the 30kW and larger models, the unit can be used in a temperature range of -10 to
+50°C with the cover left attached.
(*5): The models with a capacity of 30kW or more have uncovered wide-opened wiring holes and the unit
has no space in it which is large enough to bend external cables. So, use a optional wiring hole covers
when installing the unit outside.
(*6): Protect the inverter from over-current caused by output-side ground fault.
