Chapter 1 Safety Information and Precautions At Wiring ■ DANGER • Wiring must be performed only by qualified personnel under instructions described in this manual. Failure to comply may result in unexpected accidents. • A circuit breaker must be used to isolate the power supply and the controller. Failure to comply may result in a fire.
Page 9
Chapter 1 Safety Information and Precautions After Power-On ■ DANGER • Do not open the cover of the controller after power-on. Failure to comply may result in electric shock. • Do not touch any input or output terminal of the controller with hands. Failure to comply may result in electric shock.
Do not connect the surge suppressor to the output side of the controller. 6. Altitude and De-rating In places where the altitude is above 1000 m and the cooling effect reduces due to thin air, it is necessary to de-rate the controller. Contact Inovance for technical support. - 9 -...
