Tie the output wiring using the Model:TCB-PCIN4E SMMS-i 1 or 2 Output control board 7 -b 8 3 • Read these “Precautions for Safety” carefully before installation work. • The precautions described below include important items regarding safety. Observe them without fail.Understand the following details (indications and symbols) before reading the body text, and follow the instructions. The meanings of indications WARNING Text set off in this manner indicates that failure to adhere to the directions in the warning could result in serious bodily harm or loss of life if the product is handled improperly. CAUTION Text set off in this manner indicates that failure to adhere to the directions in the caution could result in serious bodily injury or damage to property if the product is handled improperly. • After completion of installation, perform trial operation to check for any problems. Explain method of use and maintenance to the customer by following the descriptions in the manual. Ask customer to keep this Manual at accessible place for future reference. Installation 1. Before starting installation work, be sure to turn the power supply OFF. 2. Install the "Optional PCB" at the position on the electrical components box shown in the figure on 3. 4. 5. 6. Optional PCB 9 the right. Install the "Optional PCB" at the specified location inside the electrical components box using the fixing support. There are four mounting holes for the fixing support at specified locations inside the electrical components box. Connect the connector (PJ20 (green)) on the "Optional PCB" to the connector (CN511 (green) or CN514 (green)) on the "interface PCB" using the connector cable (provided). (See figure on right.) The cable (provided) is long. Tie it using the binding band. Output wiring 8 3. [PCB Installation Position] SMMS-i SMMS-i Connector Positions MMY-MAP080 to 120 MMY-MAP140, 160 7 2.

If installation is carried out by an unqualified individual, fire or electric shock may result. • Perform installation work reliably according to this installation manual. Incomplete installation may cause electric shock, fire or abnormal operation. • Electrical work must be performed by a qualified installer or qualified service person in accordance with this installation manual. The work must satisfy all local, national and international regulations. Inappropriate work may result in electric shock or fire. • Connect the specified wires firmly and clamp them securely so that external force applied to the wires does not affect the connector pins. Improper wire connection or clamping may result in fire or malfunction. • Do not disassemble, modify, repair or move the product yourself. Doing so may cause fire, electric shock, injury or water leaks. • Ask a qualified installer or qualified service person to do any repairs or to move the product. 1 7 -b 9 7 -a Precautions for Safety 1 Wiring Optional P.C. board • Up to total of two boards Optional PCB (right side) 2. shown in the figure is removed and an upper right hook is slipped, an interface board will open.
