Dialogic SS7G21, SS7G22 manual If Ac Power Supplies Are Installed Mains Ac Power Disconnect

Chapter 1 Warnings and Cautions

WARNING

IF AC POWER SUPPLIES ARE INSTALLED:

MAINS AC POWER DISCONNECT:

The AC power cord(s) is considered the mains disconnect for the product and must be readily accessible when installed. If the individual product power cord(s) will not be readily accessible for disconnection then you are responsible for installing an AC power disconnect for the entire rack unit. This main disconnect must be readily accessible, and it must be labelled as controlling power to the entire rack unit, not just to this product. To remove all power, two AC cords must be removed.

GROUNDING THE RACK INSTALLATION:

To avoid the potential for an electrical shock hazard, you must include a third wire safety ground conductor with the rack installation. If the product power cord is plugged into an AC outlet that is part of the rack, then you must provide proper grounding for the rack itself. If the product power cord is plugged into a wall AC outlet, the safety ground conductor in the power cord provides proper grounding only for this product. You must provide additional, proper grounding for the rack and other devices installed in it.

OVERCURRENT PROTECTION:

The product is designed for an AC line voltage source with up to 20 Amps of overcurrent protection per cord feed. If the power system for the equipment rack is installed on a branch circuit with more than 20 Amps of protection, you must provide supplemental protection for the product. The overall current rating of the product configured with two power supplies is less than 2.5 Amps.

WARNING

AC POWER CORD:

Do not attempt to modify or use an AC power cord that is not the exact type required. You must use a power cord that meets the following criteria:

1.Rating: For U.S./Canada cords must be UL Listed/CSA Certified type SJT, 18-3 AWG. For outside U.S./Canada cords must be flexible harmonized (<HAR>) or VDE certified cord with 3 x 0.75mm conductors rated 250 VAC.

2.Connector, wall outlet end: Cords must be terminated in grounding-type male plug designed for use in your region. The connector must have certification marks showing certification by an agency acceptable in your region and for U.S. must be rated 125% of overall current rating of the product.

3.Connector, product end: The connectors that plug into the AC receptacle on this product must be an IEC 320, sheet C19, type female connector.

4.Cord length: Cords must be less than 4.5 meters (14.76 feet) long.
