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.

Caution when performing service inside the EL. Compo. box
WARNING
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
