Cautions during Use
• Follow instructions in 'Cautions during Use' .
Otherwise, It may cause unexpected accidents.
• Power supply should be insulated and limited voltage / current or Class 2, SELV power
supply device.
• Install a power switch or circuit breaker in the easily accessible place for supplying or
disconnecting the power.
• Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line filter or varistor at
power line and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high
frequency noise.
