Note 1 When an input is not being used, short the V IN, I IN and COM terminals.
2 Separate wiring from power lines (AC power supply lines, high-voltage lines, etc.)
3 When there is noise in the power supply line, install a noise filter on the input section and the power supply.
4 When external power is supplied, or when the power is interrupted, there may be a pulse status analog
output of up to 1 ms. If this status is a problem, take the following measures.
• Turn ON the power to the CP2E N-type CPU Unit, check the operation status, and then turn ON the
power at the load.
• Turn OFF the power to the load and then turn OFF the power to the CP2E N-type CPU Unit.
