NOTES
1 In case you use the central remote control, connect it to the unit in accordance with the attached manual.
2 When connecting the input wires from outside, fresh-up or on/off control operation can be selected. (Contact with a minimum applicable load of 12V DC, 1mA)
3 For details of connection see the attached manual of the option kit.
4 SS1 (A1P) has already been set to “nor.” qt factory set. The unit will not run if the setting is changed.
1 Do not open the EL. Compo. box cover for 10 minutes after the power supply is turned
off.
2 After opening the EL. Compo. box, measure the points shown at the right with a tester
and confirm that the voltage of the capacitor in the main circuit is less than DC50V
