Safety Considerations
To avoid getting an electric shock, and to avoid damaging the VIU–323, servicing the
VIU-323 should be performed by qualified technical personnel only.
High Voltage
Disconnect the VIU-323 from the power line before removing the cover. Avoid any
adjustment, maintenance, and repair of the opened unit under voltage as much as possible.
These actions should only be carried out by a skilled person who is aware of the dangers
involved. Capacitors inside the instrument may still be charged, even if the unit has been
disconnected from the power source. Wrist strap use is mandatory.
Grounding
Before connecting the VIU-323 to the power line, the unit's protective earth terminals must
be connected to the protective conductor of the (main) power cord. The main plug should
only be inserted in a socket outlet that has a protective earth contact. Don't use an extension
cord (power cable) that doesn't have a protective conductor (grounding). The VIU-323 can
become dangerous when you interrupt any of the protective (grounding) conductors or
disconnect any of the protective earth terminals. Intentional interruption is prohibited.
