ATTENTION!
If the inverter is stored for long periods, we recommend to
power it up once a year during 1 hour. For all models apply
single-phase supply, 50 or 60 Hz compatible with the inverter
supply, without connecting motor at output. After this
energization, wait 24 hours before operatinf it.
When required to clean the inverter, flow the instructions below:
a) Cooling System:
Remove AC power from the inverter and wait 10 minutes.
Remove all dust from ventilation openings by using a plastic
brush or a soft cloth.
Remove dust accumulated on the heatsink fins and from
the blower blades with compressed air.
b) Electronic Boards:
Remove AC power from the inverter and wait 10 minutes.
Disconnect the inverter cables, ensuring that they are
marked carefully to facilitate later reconnection.
Remove all dust from the printed circuit boards by using an
anti-static soft brush and/or remove it with an ionized
compressed air gun; (for example: Charges Burtes Ion Gun
(non nuclear) Ref. A6030-6 DESCO).
