READ ALL INSTRUCTIONS BEFORE USING THISPRODUCT!!!!

DANGER: TO REDUCE THE RISK OFELECTRIC SHOCK:

1. Always turn off power at source before installing the outlet.

WARNING: TO REDUCE THE RISK OF

BURNS, FIRE, ELECTRIC SHOCK, OR INJURY TOPERSONS:

• Always turn off power at source before servicing orremoving the outlet.

• Do not use outdoors - for indoor use only!• Route cables as shown in these installation

instructions.• To disconnect, turn off power at source.

WARNING: RISK OF ELECTRIC SHOCK!Make sure the outlet is properly grounded. See GroundingInstructions.

WARNING: Failure to provide adequatestructural strength for this outlet can result in serious personalinjury or damage to equipment! It is the installer’s responsibilityto make sure the structure to which this outlet is attached cansupport the weight of the box.

CAUTION: This equipment must be installedand assembled by qualified service personnel in accordancewith local building and electrical codes.

NOTE: Knockouts are provided for ease of installation. Anyunused knockouts that have been punched are to beclosed up with a metal plug.

NOTE: Ambient Temperature - The manufacturer’s maximumambient temperature is 104°F (40°C) and minimumambient temperature is 30°F (-1°C) so that the installeris able to determine acceptability of use of Accessoriesand components.

Isolated Ground ReceptacleThis product incorporates an isolated ground receptacle,identified by the orange triangle on its face. This feature may beuseful to reduce common noise in the connected equipment. Itsintended use is to reduce electrical noise (electromagneticinterference) by purposely insulating the grounding circuit fromany metallic wiring system. The ground pin of the receptacle isconnected to the green/yellow wire and is isolated from themetal mounting yoke of the receptacle. The accessible metal ofthe product is connected to the green wire. If it is not desired touse this feature, connect the green/yellow and green wirestogether.

• (D) Isolated Ground Receptacles. Where installedfor the reduction of electrical noise (electromagneticinterference) on the grounding circuit, a receptaclein which the grounding terminal is purposefullyinsulated from the receptacle mounting means shallbe permitted. The receptacle grounding terminalshall be connected to an insulated equipmentgrounding conductor run with the circuit conductors.This equipment grounding conductor shall bepermitted to pass through one or more panel boardswithout a connection to the panel board groundingterminal bar as permitted in 408.40, Exception, soas to terminate within the same building or structuredirectly at an equipment grounding conductorterminal of the applicable derived system or service.Where installed in accordance with the provisions ofthis section, this equipment grounding conductorshall also be permitted to pass through boxes, wireways, or other enclosures without being connectedto such enclosures.

• Informational Note: Use of an isolated equipmentgrounding conductor does not relieve therequirement for grounding the raceway system andoutlet box.

C22.2 No. 1, “Canadian Electrical Code, Part 1”, Rule 10-906Bonding conductor connection to circuits and equipment.

• (6) A bonding jumper shall be installed to connectthe bonding conductor to the grounding terminal ofa receptacle and in such a manner thatdisconnection or removal of the receptacle will notinterfere with, or interrupt grounding continuity.

• (7) In the case of metallically enclosed systemswhere the grounding path is provided by the metalenclosure, a bonding jumper shall be installed tobond the grounding terminal of the receptacle to theenclosure.

• (8) Notwithstanding Sub-rules (6) and (7), thebonding jumper, in the case of receptacles havinggrounding terminals isolated from the mountingstrap required for special equipment, shall be

permitted to be extended directly back to thedistribution panel.

WARNING: IMPROPER INSTALLATION CAN RESULT INDEATH OR SERIOUS PERSONAL INJURY! This mountingsystem should be installed by qualified personnel.

IMPORTANT ! : In addition to the CMS491/CMS491C/CMS492/CMS492C installation instructionsaccompanying the products, the following steps mustalso be taken when installing the CMS491P2,CMS491CP2, CMS492P2, and CMS492CP2.

The CMS491P2, CMS491CP2, CMS492P2, and CMS492CP2must be connected to a 15 Amp branch circuit.

Installing EGX-SF21. Loosen two Phillips head screws holding EGX-SF2 (A)

outlet box to outer housing. (See Figure 1)

2. Rotate outlet box counter-clockwise until it is free to beremoved from housing. (See Figure 1)

3. Remove outlet box from housing. (See Figure 1)

4. Wire the EGX-SF2 outlet box as required making sure thewiring passes through the outlet hole in the housing. Refer toTable 1 and Table 2 for input and output specifications. (SeeFigure 2)

Table 1: Input Specifications

Table 2: Output Specifications

CAUTION: Isolated ground-mounting means NOTgrounded. Grounding wire connection required.

IMPORTANT ! : If a separate isolated green/yellowground wire is installed in the building wiring, attach itseparately to the green/yellow isolated ground wire onbox. If there is no separate green/yellow isolated groundwire, connect green ground wire to both green/yellowisolated ground wire and green box ground wire on box.

NOTE: The grounding conductors serving this outlet are to beconnected to earth ground at the service equipment orother acceptable building earth ground such as thebuilding frame in the case of a high-rise steel-framestructure. Connections should be made with minimumAWG 14 copper wire intended for use on a 15 Ampcircuit. The conductors used to connect the outlet to theline and to ground shall not be any longer thannecessary and shall avoid unnecessary bends.

NOTE: An insulated grounding conductor that is identical insize and insulation material and thickness to thegrounded and ungrounded circuit supply conductors,except that it is green with or without one or moreyellow stripes, is to be installed as part of the circuit thatsupplies the outlet. Refer to Table 250-122 of theNational Electrical Code regarding the appropriate sizeof the grounding conductor.

NOTE: Pressure terminal or pressure splicing connectors andsoldering lugs used in the installation of the outlet shallbe identified as being suitable for the material of theconductors. Conductors of dissimilar metals shall notbe intermixed in a terminal or splicing connector wherephysical contact occurs between dissimilar conductorsunless the device is identified for the purpose andconditions of use.
