[Pulse signal input function]
Using pulse signals directly input from metering device such as watt-hour meter, billing data and energy
management data will be obtained based on the cumulative number of pulse signal input.
Note
● To input pulse signals directly from the metering device to the EW-50E, use the connector connected to the EW-50E.
(Aprecision screwdriver for M1 screws is required.).

*1 A built-in PI controller on the AE-200E cannot be used for an apportioned electricity billing function. Use a built-in PI controller on the
AE-50E or EW-50E.
*2 Using a PI controller (PAC-YG60MCA) is recommended instead of a built-in PI controller on the AE-50E/EW-50E when using an apportioned
electricity billing function. (Discrepancies may occur between the built-in PI controller reading and the actual electric energy because the
pulse input cannot be obtained during the AE-50E/EW-50E power failure, shutoff process, and software update.)

A voltage of 12 VDC is applied to CN7. Do not apply a power
voltage from any other power source.

Rated voltage: 12 VDC
Rated current: 0.1 A or above
Minimum applied load: DC 1 mA
Note
● The total length of the lead wire and extension cable should not exceed 100 m (328 ft). (Use an extension cable of
0.3 mm
2
or thicker.)
● Cut the excess cable near the connector, and insulate the end of the unused cable with tape.
● Do not run the signal input cable adjacent to the M-NET transmission and power cables. Do not let the cable form a loop.
● Peel off the sheath to 6 ±1 mm (4/16 ±1/16 in) from the end, and securely insert the cable into the terminal.
● Leave adequate slack in the cables so that the weight of them will not strain the terminal connectors. Use cable clamps
or trunk terminals as necessary.
