Replacement
to test integrity of the connection. Repeat this procedure from step 2 if the wires release
easily. Replace sensor cover.
This equipment has fuses in both neutral and phase lines. Use care when servicing.
Occasionally, one or both of the fuses in the analyzer may burn out. The fuses are located
in the power receptacle on the left hand side of the analyzer.
Before servicing the fuses,
disconnect the power cord from the local power supply and from the power entry mod-
ule.
Both fuses should be checked each time fuse replacement is warranted. To access the
fuses, use a small screwdriver to remove the holder located in the power receptacle of the
generator (see Figure 5). Replace either one or both fuses as necessary and re-assemble.
For continued protection against risk of fire, replace only with fuse of specified rating.
