UL 1283 required language concerning the installation of EMI Filters
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. Reference should be made to Table
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
c)Any
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.
Additional instructions for TPS3 01 & L1 SPDs including:
W option Suffix:
The W option includes respositioned phase connection tabs that allow for wire connections to a circuit breaker within the panelboard. This differs from
The circuit breaker serves as a disconnector device and overcurrent protection to the connecting conductors. The TPS3 SPD includes internal overcurrent and overtemperature protective equipment. The breaker does not provide overcurrent protection to the SPD.
Recommended breaker and conductor size is 60A with a 6 AWG conductors. Other combinations are possible. Terminal lugs will accept
Circuit breaker MUST be located immediately adjacent to SPD to minimize lead lengths. Move or adjust breaker positions as appropriate. Every effort must be taken to reduce lead lengths. Failure to install short leads will degrade SPD performance.
Install appropriate circuit breaker in panelboard.
Prior to installing SPD, rotate and tighten lug terminals toward breaker location.
Mount the SPD using supplied hardware.
Connect the neutral connection by wire or bracket as appropriate.
Install conductors, short and straight as possible. Use gentle radius on any bends. Do not kink wires. Prevent wires from encroaching breaker locations.
Torque all connections to the values specified on the installation and maintenance instruction label affixed to the rear of the dead front.
Replace dead front supports and trim.
Energize breaker and confirm proper SPD operation.
