Safety Considerations
To avoid getting an electric shock, and to avoid damaging the MCU-323, servicing the
MCU-323 should be performed by qualified technical personnel only.
Grounding
Before connecting the MCU-323 to the power line, the unit’s protective earth terminals
must be connected to the protective conductor of the power cord. The power plug should
only be inserted into a power outlet that has a protective earth contact. Do not use an
extension cord that does not have a protective conductor (ground). The MCU-323 can
become dangerous if you interrupt any of the protective (grounding) conductors or
disconnect any of the protective earth terminals.
High Voltage
Disconnect the MCU-323 from the power line before removing the cover. Avoid any
adjustment, maintenance, or repair of the opened unit under voltage. 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.
