WARNING
Risk of death from electric shock when installation of lamp sockets is non-insulated
If two incandescent lamps connected in series are used, the insulation of the lamp
sockets is not rated for the high voltage of 500 to 690 V 3 ph AC.
• For a line voltage of 500 to 690 V 3 ph AC, install the two lamp sockets connected in
series with insulation and protect them from being touched.
