6.3.3 Cautions
Before applying the load, always set the power supply. Connect the load using
isolated cords with sufficient diameter. Disconnect the load before switching off the
power supply. Keep the instrument away from dust.
Any interruption of the protective conductor outside the case or any
disconnecting of the earth terminal may render the instrument dangerous.
The intentional interruption is forbidden.
6.4 APPLICATIONS
As outputs are floating, limited by the maximum common voltage, the reference is
given by the mounting diagram (Fig. 2).
The power supply can deliver a positive or negative voltage.
7. MAINTENANCE
No particular maintenance is required for this instrument.
Avoid dust, moisture, shocks ; your instrument will be grateful for that.
For the cleaning, please use a smooth duster.
If indicators do not light up on switching on, check :
- That the «ON/OFF» switch is pressed
- The mains voltage
- The connection to mains
- The protective fuse.
8. AFTER SALES SERVICE
