where the inverter is operating at maximum power output for
extended periods.
The unit will shut down if the internal temperature exceeds
90
º
C. It will restart once it cools off.
CAUTION: PROwatt 250 CASE GETS HOT
The case of the PROwatt 250 acts as a heat sink, dispersing in-
ternally generated heat. When the PROwatt 250 is operating at
high power levels (above 100 watts) for extended periods, the
case will get hot. Surface temperatures may approach 60
º
C
(140
º
F) on some parts of the case. When operating at high
power levels, do not place the PROwatt 250 on or near materials
that may be affected by these temperatures. Use caution when
handling the PROwatt 250 if it is operating at high power lev-
els.
d) Safe
- do not use the PROwatt 250 near flammable materials
or in any location which may accumulate flammable fumes
or gases.
4. Operating Tips
4.1 Rated versus actual current draw of equipment
Manufacturers of electrical and electronic equipment often over
rate the current drawn by their products. If a piece of electrical
or electronic equipment is rated at 300 watts or less, the PRO-
watt 250 will probably operate it. The inverter has overload
protection, so it is safe to try it with equipment rated at 300
