CAUTION

5. Plugging/Unplugging ERC2PIO Teaching Tools

[1] When plugging or unplugging a teaching tool (PC software/teaching pendant) connector, make sure the

power is turned off. If the connector is plugged or unplugged while the power is on, internal circuits may be

damaged.

[2] Install a diode in parallel with the relay coil shown in the circuit diagram below, or use a relay coil with built-

in diode. If there is no diode, internal circuits may be damaged.

* To eliminate noise, install noise killers (or diodes in the case of DC circuit) for the coils of all relays,

solenoid valves, etc. This is also mentioned in the operation manual.
