Hazardous voltage.
Will cause death or serious injury.
Keep Out.
Qualified personnel only.
Disconnect and lock off all power before
working on this equipment.
TPS3 01 and TPS3 06 Module Installation
Instructions: MCC
The following instructions are for the replacement of Siemens TPS3
SPD module in a TIASTAR MCC.
This unit is intended for custom factory installation during MCC
manufacture. Unit must be removed from the MCC or withdrawn
to the TEST position. Familiarize with the TPS and MCC mounting
hardware-mount in gear such that the leads are as short and straight
as possible without distorting the stab assembly. Failure to do so will
result in decreased performance.
Diagnostic Display Connected via Ribbon Cable – to be mounted in a
suitable location such that the display is visible to user and/or protected
via an access door.
A successful installation includes:
• Meets all national and local codes.
• Mount TPS as close as possible to electrical connection.
• Ensure leads are as short and straight as possible.
• Gently twist or tie-wrap conductors together wherever possible.
• Ensure that N-G bonding hazard warning label is attached to TPS
as reminder to installing contractor.
•
Ensure all power is off and unit is deenergized.
•
Verify that TPS and intended voltage are correct.
•
Install #6 conductor leads to phase, neutral and ground connections.
•
Mount Diagnostic Display at appropriate location.
•
Connect ribbon cables from Diagnostic Display to circuit board on
Main TPS Backplane Assembly.
•
Connect to the Dry Contact terminal block if appropriate.
Before bench testing
• Ensure test voltage is appropriate and grounded Wye system
– Failure to ensure reference to ground will fail unit.
• Ensure unit is touch safe and that all appropriate enclosures are secure.
• Do not Hi-Pot test SPDs.
• Do not bench test using ungrounded system – must be grounded
Wye system.
Confirm that all LEDs are green and that touchpads on display operate
correctly.
UL 1283 required language concerning the installation of EMI Filters
a) An insulated grounding conductor that is identical in size and
Figure 8: Installation
insulation material and thickness to the grounded and ungrounded
in an MCC
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 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.
Additional instructions for TPS3 01 & L1, 02 & L2 SPDs including:
W Option Suffix:
The W option includes repositioned phase connection tabs that allow
for wire connections to a circuit breaker within the panelboard. This
differs from non-W models, which bolts directly to bus bars.
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
2-14 AWG. Breaker size should be at least 20A. All applicable codes
must be followed.
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.
NOTICE
CONDUCTING DIELECTRIC AND/OR
HI-POTENTIAL TESTING WILL CAUSE
INTERNAL DAMAGE TO TPS3 UNIT.
Do not perform dielectric or high potential
tests with the TPS3 unit installed.
