Electrical Safety

To avoid an electric shock or damage to the Cisco Unified Videoconferencing 3500 Gateway unit, servicing should be performed by qualified service personnel only.

To reduce the risk of damaging power surges, Cisco recommends installing an AC surge arrestor in the AC outlet from which the Cisco Unified Videoconferencing 3500 Gateway unit is powered.

Warning Do not attempt to open the Cisco Unified Videoconferencing 3500 Gateway unit.

Warning Changes or modifications to the device that are not approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Grounding

The power cable of the Cisco Unified Videoconferencing 3500 Gateway 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 3500 Gateway unit can become dangerous if you interrupt any of the protective conductors (grounding) or disconnect any of the protective earth terminals.

Caution For North American installations, select a 3-conductor (18 AWG) power supply cord that is UL listed and CSA certified. The cord must be terminated in a molded-on plug cap rated 125V/5A, with a minimum length of 1.5m (6 feet) and no longer than 4.5m (approximately 14 feet).
