6-2. Installation Instructions 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 horizontally, or as shown below, vertically.

(3) Refer to "7. Wiring Instructions" and connect the wires for the power line, M-NET transmission line, and meter input signal lines. Meter input signal lines M-NET Power line PI controller 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.

7-2. Connecting the Power and M-NET Transmission Lines Tightening torque for terminal screws: 1 N·m Connect the M-NET transmission line of this 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).
PAGE 10
7-3. Connecting the Signal Lines • Separately procure items such as terminal blocks and cables locally. • The maximum wire length is 100 m (328 ft). However, since the use of long wires makes the device susceptible to noise, using wires shorter than 10 m (32.8 ft) is recommended. (1) Pulse input (non-voltage a-contact) * To use these, various settings need to be configured. Refer to "8. Initial Settings". Note: • The pulse unit (weight) can be added to each of the inputs of channels 1 to 4.
PAGE 11
8 Initial Settings After completing the procedures described in "6. Installation" and "7. Wiring Instructions", set the initial settings in accordance with the procedure described below. (1) M-NET address settings 10s SW06 1s Note: • An address from 01 to 50 can be set. • Set an address that is not the same as that of another unit. The address is set to "01" at factory default. SW07 In the case of address "41" (2) Use the dip switches to select functions.
