Switching off procedure
If necessary and in case of dangerous situation, it is possible to insulate the device
totally, using the following switching off procedure:
•
disconnect the AC source;
wait few seconds for total discharge
or
•
open the output protection switch that disconnect the output wires. This
procedure does not insulate the device but interrupts the output voltage.
DEVICE PROTECTIONS
The device has the following protections:
Input protection
Automatic switch to protect mains.
Output protection
Overload
The equipment is electronically self-protected, cutting off the output voltage after 5
seconds. The overload red indicator is lit. To restart the unit, use ON-OFF frontal switch.
Short circuit
The equipment is electronically self-protected, cutting off the output voltage after 5
seconds. The overload red indicator is lit. To restart the unit, use ON-OFF frontal switch.
Internal protection
Over temperature protection
In case of internal over temperature, the equipment is automatically protected at 70°C.
The system shut downs the output voltage and red stop temperature indicator is on.
