WIRING
WARNING
Do not open the cover of the terminal block while power is
being supplied. Doing so can result in electric shock if the
operator touches an electrode.
After wiring, make sure that the cover is locked properly. If
the cover is open, electric shock can result if the operator
touches an electrode.
If the cover of the terminal block is damaged or lost, do not
use the terminal block. Promptly replace it with a new one.
„ Wiring precautions
•
Before wiring, verify the model No. and terminal Nos. written
on the label on the side of the main unit.
•
Use M3 crimp-type terminal lugs for wiring to a screw-type
terminal block.
•
Take particular care that crimp terminal lugs, etc. do not make
contact with adjacent terminals.
•
Leave a distance of at least 30 cm between I/O lead wires and
communications lead wires or power lead wires. Also, do not
pass these lead wires through the same conduit or wiring duct.
•
After wiring, always check that the wiring is correct. Incorrect
wiring will cause damage and incorrect operation.
•
The connectors listed below use the same kind of hardware.
Make sure to avoid wiring errors.
• Connector for the RX-R control signal connection (connec-
tor CN6) and Connector for the RX-L control signal connec-
tion (connector CN7)
•
The loader jack and terminal block are located close to each
other. Be careful of electric shock when inserting the loader
cable because high voltages are applied to the terminal block.
Loader jack
High-voltage terminals (AC)
When using the PC loader, make sure there is sufficient ma-
neuvering room so that a hand or foot does not get caught on
the loader cable.
•
To remove the loader jack cover, turn it counterclockwise 90°
using a screwdriver. After removal, take care not lose the cover.
After removing the loader cable, put the jack cover on the jack
and turn the cover clockwise 90° using a screwdriver until it
reaches the locked position.

Handling Precautions
•
The terminal block A and the terminal block B use the same
kind of hardware. Make sure to avoid wiring errors.

*1. Use the reset input by itself. It cannot be used together with another
RX-L reset input.
*2. The COM terminal cannot be used together with another RX-L.

* Example of wiring to an ECM3000 control motor. In the example, the
ECM3000 auxiliary switches are used as the high combustion interlock
and the low combustion interlock, and terminal A on the RX-L is assigned
to interlock inputs IN7 and IN8.
