ASCO 460/465/480/485 Surge Protective Device (SPD)
Operation
UL 1283 required language
concerning the installation of
EMI Filters (standard on Type
2 models)
Operation
A. An insulated grounding conductor that is identical in size and insulation
material and thickness to the grounded and ungrounded circuit supply
conductors, except that it is green with or without one or more yellow
stripes, is to be installed as part of the circuit that supplies the filter. Ref
-
erence should be made to Table 250-122 of the National Electrical Code
regarding the appropriate size of the grounding conductor.
B. The grounding conductor mentioned in item a is to be grounded to earth
at the service equipment or other acceptable building earth ground such
as the building frame in the case of a high-rise steel frame structure.
C.
Any attachment-plug receptacles in the vicinity of the filter are to be of a
grounding type, and the grounding conductors serving these receptacles
are to be connected to earth ground at the service equipment or other
acceptable building earth ground such as the building frame in the case
of a high-rise steel-frame structure.
D. Pressure terminal or pressure splicing connectors and soldering lugs
used in the installation of the filter shall be identified as being suitable for
the material of the conductors. Conductors of dissimilar metals shall not
be intermixed in a terminal or splicing connector where physical contact
occurs between dissimilar conductors unless the device is identified for
the purpose and conditions of use.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, CSA Z462 or NOM-029-STPS.
•
This equipment must only be installed and serviced by qualified electrical
personnel.
•
Turn off all power supplying this equipment before working on or inside
equipment.
•
Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this
equipment.
•
This equipment must be effectively grounded per all applicable codes. Use
an equipment-grounding conductor to connect this equipment to the power
system ground.
Failure to follow these instructions will result in death or serious injury.
