WARNING
Electric shock hazard in case of contact
When the main isolator is set at O, items located between the mains connection and the
isolator are still under mains voltage.
Disconnect the power line cable from all power sources before doing any work on the
product.
WARNING
Electric shock hazard
Some components have capacitors charged to over 60VDC. When power is switched
off, they maintain this charge for some time. Residual voltages from the filter capacitors
can cause electric shocks all the way back to the mains plug.
Wait 5 minutes after power-off before commencing any work on the product.
