4.1 MAINTENANCE & INSPECTION
This section describes basic maintenance and inspection procedures for
the FP5/GP5.
Periodic Inspection
The FP5/GP5 will function longer if it is kept clean, cool and dry,
and if all precautions highlighted in this manual are observed. Periodi-
cally inspect the inverter as described in the table below to prevent acci-
dents and to ensure high performance with high reliability.
To prevent electrical shock, disconnect all power before servicing the
inverter. Then wait at least five minutes after the power supply is discon-
nected and all LEDs are extinguished.
Parts Replacement Schedule
Replace the following parts periodically, for long, safe, trouble-free oper-
ation of the FP5/GP5:
