Operator Maintenance
This section describes how to replace the power line fuse and clean the
power meter. If you need additional information about replacing parts or
repairing the power meter, refer to the
EPM Series Power Meter Service Guide
.
To clean the power meter, disconnect its supply power and wipe with a
damp cloth only.
The power line fuse is located within the power meter’s fuse holder
assembly on the rear panel. For all voltages, the power meter uses a
250 V, T2.5 H, 20 mm slow blow fuse with high breaking capacity.
Replacing the Power Line Fuse
1 Slide the fuse holder assembly from the rear panel as shown in
Figure 9- 3.
2 Install the correct fuses in the respective “In line” positions as shown
in Figure 9- 3. (The N1913A/1914A requires two fuses.)
3 Replace the fuse holder assembly in the rear panel.
Figure 9-3 Replacing the fuses
The power meter also has an internal fuse. If you suspect that this fuse needs to be
replaced, it must be done by trained service personnel. Please refer to “Returning Your
Power Meter for Service” on page 212.
