Mitsubishi Electronics PAC-YG60MCA User Manual

8

• Separately procure items such as terminal blocks and cables locally.

• The maximum wire length is 100 m. However, since the use of long wires makes the device susceptible to 

noise, using wires shorter than 10 m is recommended.

(1) Pulse input (non-voltage a contact)

* To use these, various settings need to be configured. Refer to "8 Initial Setting Procedure".

Note: 

• The pulse weight can be added to each of the inputs of 

channels 1 to 4.
For details, refer to "9 Switch List".

• This device does not support level meters.

To use a level meter, incorporate a Converter circuit 
externally and convert to pulse input.

 Caution:

• The polarity of the input terminals is important, so be sure to 

match the polarity when using contacts that have polarity. 

• Select a contact with a minimum applicable load of 1 mA or 

less.

• Supply 24 VDC 1 mA from the positive terminal to the 

contacts of the meters.

• The pulse unit of the watt-hour meter being used should be 

1 kWh/pulse or less. Note that the apportioning error will 
increase if a watt-hour meter with large pulse unit is used.

• Strip 12±1 mm (15/32 ±1/32 in) of the wire coating and insert 

firmly into the terminal.

• Make sure that the copper wiring is not short-circuiting the 

plates (cover, lower case) or neighboring wires.

• Perform wiring so that the terminal block is not strained.

If strained, use a wire guide or junction terminal to alleviate 
the stress on the terminal block.
