2. INSTALLATION AND WIRING
2.6 Control circuit
NOTE
• When using stranded wires without a blade terminal, twist enough to avoid short circuit with a nearby terminals or wires.
• Never change the control logic while power is ON.
• Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage
or injury.
Wire removal
Pull the wire while pushing the open/close button all the way down firmly with a flathead screwdriver.
NOTE
• Pulling out the wire forcefully without pushing the open/close button all the way down may damage the terminal block.
• Use a small flathead screwdriver (tip thickness: 0.4 mm, tip width: 2.5 mm).
If a flathead screwdriver with a narrow tip is used, terminal block may be damaged.
Commercially available products (as of February 2016)
• Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage
or injury.
Common terminals of the control circuit (SD, PC, SE)
• Terminals SD (sink logic), PC (source logic), and SE are common terminals (0 V) for I/O signals. (All common terminals
are isolated from each other.) Do not earth (ground) these terminals.
• In the sink logic, terminal SD is a common terminal for the contact input terminals (RES, OH, RDI). The open collector
circuit is isolated from the internal control circuit by photocoupler.
• In the source logic, terminal PC is a common terminal for the contact input terminals (RES, OH, RDI). The open collector
circuit is isolated from the internal control circuit by photocoupler.
• Terminal SE is a common terminal for the open collector output terminals (RDA, RDB, RSO, IPF, FAN). The contact input
circuit is isolated from the internal control circuit by photocoupler.
Signal inputs by contactless switches
The contact input terminals of the converter unit (RES, OH, RDI) can be controlled using a transistor instead of a contact switch
as shown in the following figure.
