2.3.7 MAINTENANCE

Service and repairs must be carried out by skilled and authorized personnel.
Before carrying out any maintenance operation, Fluxpower HE must be
disconnected from AC and DC supply sources.
The device is provided with internal isolators which allow it to isolate the
internal power circuits. However the voltages of the supply sources are present
at the terminals. To isolate the device completely, provide external circuit
breakers on the lines.
The device contains dangerous voltages even after shutdown and
disconnection from the supply sources, due to the internal capacitors which
discharge slowly. Thus we recommend to wait at least 5 minutes before
opening the device doors.
INJURY HAZARD DUE TO ELECTRIC SHOCK!
Any operation must be carried out only when voltage is absent and in
compliance with safety directives.
Make sure the battery circuit breaker that may be placed near the battery
has been opened
Isolate the device completely by operating the external circuit breakers
Wait at least 5 minutes in order to allow the capacitors to discharge
After switching off and disconnecting the device there might still be very hot
components (magnetic parts, heat sinks); therefore we recommend using
protective gloves.
HIGH TEMPERATURE OF COMPONENTS
It is strongly recommended to use protective gloves due to the high
temperatures that may be reached during operation.
