Notes
X35A is connected when optional
accessories are being used, see
wiring diagram of this accessory
An EKVDX unit and its
corresponding VAM-J8 unit
should be connected to a
common power supply. Refer to
the installation manual of the
EKVDX unit for further details.

Ext. output - error state
Ext. output - R32 alarm
Caution when performing service
inside the el. compo. box
Caution for ELECTRIC SHOCK
Do not open the el. compo. box
cover for 10 minutes after the
power supply is turned off.
After opening the el. compo. box,
measure (on A1P~A5P) 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.
