Grounding

The power cable of the Cisco Unified Videoconferencing 3515 MCU unit should only be connected to a power outlet that has a protective earth contact. Do not use an extension cord that does not have a protective conductor (ground). The Cisco Unified Videoconferencing 3515 MCU unit can become dangerous if you interrupt any of the protective conductors (grounding) or disconnect any of the protective earth terminals.

High Voltage

Disconnect the Cisco Unified Videoconferencing 3515 MCU unit from the power line before removing the cover. Avoid any adjustment, maintenance, or repair of an opened chassis under voltage. These actions should only be carried out by a skilled person who is aware of the dangers involved. Capacitors inside the chassis may still be charged, even if the unit has been disconnected from the power source.

ESD Procedures for the 3515 MCU

To prevent damage to the Cisco Unified Videoconferencing 3515 MCU unit by random electrostatic discharge (ESD), the use of wrist straps is highly recommended.
