instructions manual.
3. INSTRUCTIONS FOR USE
3-1 Safety instructions
The instrument must be used according to the instructions of this manual.
Made to be used indoors, do not expose to the rain.
For a natural and correct cooling, the power supply must stand on its four rubber
thrusts and all ventilations must be widely cleared.
The plug of the feeding cable being used as the switch off device, the instrument
must be connected to a mains socket (230V 50/60Hz) easily accessible
No intervention is authorized inside the casing.
3-2 Use
Plug the power supply to the input voltage 220 - 240 V (O/I switch). The 2 green LED "ON"
lights up, your instrument is ready to work.
4. WORKING
ALF1501D is regulated, stabilised and protected power supply.
- Choose the symetrical output voltage thanks to the fine voltage adjustment.
- Connect the power supply on main, the 2 green LED light up.
- Connect the charge.
If the power required is higher than that the power supply can provide, a power limitation starts
(tripping), the 2 LED will turn off.
5. MAINTENANCE
No particular maintenance is required for this instrument.
Avoid dust, moisture, shocks : your instrument will be grateful for that.
If the green indicator does not light up when switching on, check :
- The mains voltage
- The connection to mains.
6. AFTER SALES SERVICE
During TWO YEARS, spare parts and workmanship are guaranteed. This guarantee does not
apply to instrument presenting defects or failures caused by an improper use. Return
expenses are borne by the client. Only devices returned with a dated purchasing invoice can
be recovered by the guarantee. Any intervention carried out by unauthorized persons or
organizations, shall void the guarantee.
