♦ 1 fuse-switch triple 400 V / 10 A
♦ 3 incandescent lamps 230 V / 100 W
♦ Various small parts e.g. lamp holders, 1.5 mm
The unit has hazardous voltage levels up to 5 minutes after it has been
powered down due to the DC link capacitors. The unit or the DC link
terminals must not be worked on until at least after this delay time.
♦ Before you form the unit, all mains connections must be
disconnected.
♦ The converter incoming supply must be switched off.
♦ The unit is not permitted to receive a switch-on command (e.g. via
the keyboard of the PMU or the terminal strip).
