before changing the OUTPUT VOLTAGE setting.
To change the OUPUT VOLTAGE setting, remove the label, change the
switch setting and replace the label. Additional labels are supplied in the
accessory kit.
Installer’s Note: Changing this setting requires a corresponding change

for 220-240VAC.
10. POWER ON/OFF – Switches AC power on or off.

The fuse box is configured at the factory according to the specifications of
your order. Should you need to replace the fuse, follow these steps:

b. Insert a new fuse of the same type
and rating into the fuse box drawer.
c. Slide the fuse box drawer back into the fusebox.
