Cautions during Use
- Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
- For connecting the power, use the crimp terminal (M3.5, max. 7.2 mm)
- 24 VDC
power supply should be insulated and limited voltage/current or Class 2, SELV power supply device. - Keep away from high voltage lines or power lines to prevent inductive noise. Do not use near the equipment which generates strong magnetic force or high frequency noise.
- Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.
- Use twisted pair wire for communication line.
- This unit may be used in the following environments.
– Indoors (in the environment condition rated in ‘Specifications’)
