Safety instructions
grounding cables are installed.
1.
This product is to be installed in a Restricted Access Location only, such as dedicated equipment rooms,
service closets, and so forth.
2.
A qualified electrician must perform all connections to AC power and safety grounds, the server must be
safety grounded at all time.
3.
To avoid potential for an electrical shock hazard, you must provide proper grounding from the chassis to
an earth ground. Ground conductor is 12 AWG minimum and is connected from the earth ground stud to
the rear of the appliance. The safety ground conductor should be connected to the chassis stud (hexagon
green stud) terminated with a closed-loop ring terminal Digikey catalog part number: 920010-09-ND
manufactured by 3M (part number MVU10-8RK). Refer to instructions provided with terminals for
crimping tool and assembly instructions.
4.
Be sure to use power cords that include safety certifications. The power cords must be compliant with the
AC voltage requirements in your region. Power cords should be 18 AWG in copper and about 6 feet in
length. The power cords connect to each AC power supply unit where each wire is terminated with a lug
(Digikey catalog part number: 94774-01-ND).
5.
AC power input is at the rear of the system. Connect the AC power cords (terminated with lugs) to the
chassis power supply units and connect the other end to a circuit breaker. The circuit breaker shall be
Listed, rated max 20A, @ -48Vdc
Warning:
To avoid electrical shock, check the power cords as
follows:
Checking the Power Cords:
Use the exact type of power cords as required.
Be sure to use power cord(s) that include safety certifications.
The power cord(s) must be compliant with the AC voltage requirements in your region.
The power cord plug caps must have an electrical current rating that is at least 125% of the electrical
current rating of this product.
The power cord plug caps that plug into the AC receptacles on the power supply units must be an IEC 320,
sheet C13, type female connector.
Plug the Power cord(s) into a socket that is properly grounded before turning on the power.
Warning:
Follow the guidelines below to avoid possible damages to
the system or injury to yourself.
General electrical safety guidelines
A readily-accessible disconnect device must be incorporated into the location where Interaction Edge is
installed.
Be aware of the locations of the power switches on the chassis and in the room, so you can disconnect the
power supply if an accident occurs.
Take extra precautionary measures when working with high voltage components. It is not recommended
that you work alone.
Before removing or installing main system components, be sure to disconnect the power first. Turn off the
system before you disconnect the power supply.
Use only one hand when working with powered-on electrical equipment to avoid possible electrical shock.
Use rubber mats specifically designed as electrical insulators when working with computer systems.
