Chapter 7 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.
