  • Page 8 4. Electrical Wiring Procedure ATTENTION: Perform the electrical wiring work according to the clause "1. Safety Summary". ● Follow the local codes and regulations, and the advance guidance of the electric power company when per- forming electrical wiring. ● Perform electrical wiring connection work only by qualified electrician. ● Perform the installation work of the leakage breaker and the grounding work according to the local codes and regulations. ● Run the transmission line as short as possible and keep a distance of 15cm or more away from the power source line not to run along. If the transmission line is required to be run along the power source line, per- form the noise prevention as follows: - Run the cable of transmission or power source through the metal tube. (Earth one end of cable.) - Use the shielded cable for the transmission line. (Earth one end of the shielded cable.) ® ● Before opening the top cover of the BACnet adapter, turn OFF the power supply for UPS. And before elec- trical wiring work, ensure to turn OFF the power supply for UPS. ® Unless UPS power is turned OFF, the current is kept supplied to the terminals and switch for the BACnet adapter, which can cause electric shock when touched. ® ● The BACnet adapter has the backup system function. To realize the backup function, the “POWER LED” will stay lit for a short period after power shuts down. Please make sure that “POWER LED” is OFF upon wiring. ® ● Do NOT modify the inner system of the BACnet adapter. It will cause a malfunction.

    5. Test Running ● Before turning ON the power, ensure that the insulating resistance between the power supply terminals and the grounding line is 1MΩ or more with DC500V. Resistance less than 1MΩ shall be considered insulation failure. In that case, do NOT turn ON the power supply. ● Do NOT operate the packaged air conditioner for checking the wiring connection until the test running prepa- ration is completed. ● If accidents such as the smoke and fire occur, shut the power supply down. 5.1 Switch Setting Procedure Perform to change the switch setting before turning on the power supply.
