Confirmation of Parts • Confirm that the box contains the following parts. Number Part Name Quantity 1 PI controller 1 2 Installation/instruction manual (this document) 1 * In addition to the parts mentioned above, other parts need to be procured locally in order to operate this device. Furthermore, other Mitsubishi optional parts may be required depending on how the device is to be used. For details, refer to "6 Installation Method". 4 Specifications 4-1.

-2. Installation Procedure The PI controller PAC-YG60MCA does not have a waterproof structure. Be sure to install the PI controller inside a control panel that is located indoors. Prepare a control panel capable of storing this device such as the one shown in the figure. (Install the device in a control panel strong enough to withstand a weight of 0.6 kg [13/8 lb].) This device can be installed flat or vertically. Clear the space shown below when installing.

(3) Refer to "7 Wiring Method" and connect the wires for the power line, M-NET transmission line, and input/output signal lines. M-NET Pulse Input Power line Caution: 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. PI controller Junction terminal block 24 VDC Power source +V -V FG L N PAC-SC50KUA M-NET * The wiring in the diagram has been simplified.

7-2. Connecting the Power Line and M-NET Transmission Line Tightening torque for terminal screws: 1 N·m Connect the device to a power supply unit (PAC-SC50KUA) for the transmission line or an outdoor unit (either a centralized control line or indoor control line can be connected). * Only the M-NET circuitry of this device receives the power from the M-NET transmission line. The power consumption factor is "1/4" (equivalent to one ME Remote Controller).
PAGE 9
7-3. Connecting the Signal Lines • 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.
PAGE 10
8 Initial Setting Procedure After completing the procedures described in "6 Installation Method" and "7 Wiring Method", set the initial settings in accordance with the procedure described below. (1) M-NET address settings 10s Note: • An address from 01 to 50 can be set. • Set an address that is not the same as that of another unit. 1s The address is set to "01" at factory shipment. SW06 SW07 In the case of address "41" (2) Use the dip switches to select functions.
