Electrical Power

Internal Fuses

Detail of the electrical cabinet interior is shown in Figure
10 - 5. Inside the electrical cabinet below the base of the
AC disconnect switch is a fuse block containing three 25
Amp fuses. These are wired in series between the AC
disconnect switch and the terminal block. To gain access
to the fuses, pinch the top and bottom of the clear cover as
shown in Figure 10 - 5, and pull the cover off. There are
four locking tabs that must be released which are identi-
fied in Figure 10 - 6. Each fuse has its own red removal
tab. Pull the tab to remove the fuse. Note that the fuses
are asymmetrical and have a flanged lip on the bottom.

Circuit Breaker

The AC utility outlet on the front panel (K in Figure
4 - 2 , Page 29), is protected by a circuit breaker which
is identified in Figure 10 - 2. The maximum current that
can be safely drawn from the utility outlets is 4 Amps
total, independent of whether the outlets are wired for
110 Volts AC or 220 Volts AC.
