Siemens Surge Protective Device TPS3 12 - Manual (Page 11)

PRE-PLAN INSTALLATION TO ACCOMPLISH THE FOLLOWING:
• Meet all National and Local codes (NEC® Article 285 addresses
SPDs)
• Mount SPD as close to panel or equipment as possible to keep
leads short
• Ensure leads are as short and straight as possible, including
neutral and ground. Consider a breaker position that is closest
to the SPD and the panel’s neutral & ground
• Suggested breaker & conductor size is 60A-30A with 6 AWG
• Make sure system is grounded per NEC® and clear of faults before
energizing SPD.
CERTAIN OPTIONS OR IMPLEMENTATIONS REQUIRE EXTRA
CONSIDERATION. SEE APPROPRIATE SECTIONS WITHIN THIS
MANUAL:
• Line Side Installation (page 4)
• Disconnect Switch Option (page 9)
• Flush Mount Option (page 9)
• Retro-fit where no breaker positions are available (page 9)
• NEMA 3R drain holes (page 7)

Hazardous voltage.
Will cause death or serious injury.

Qualified personnel only.
Disconnect and lock off all power before
working on this equipment.

DANGER
Use a voltmeter to check all voltages to ensure correct SPD
If SPD has Dry Contact, Remote Monitoring or Remote Display,
pre-plan their installation
Remove power for panel. Confirm panel is deenergized.
Identify connection/breaker location and SPD location.
Make sure leads are short. Reducing inches matters.
Installation Tips: SPD module is mounted on backplane within
its enclosure. In many cases, the backplane assembly can be
unbolted and rotated in two or four directions to yield shortest
leads. See Figure 7. Carefully disconnect ribbon cable(s) and
unbolt backplane assembly. Various configurations have
limited work space. Please be patient. Installation may be
easier if disconnect switch is temporarily removed from DIN-
rail, or module/backplane is temporarily removed.
Remove an appropriately sized knockout from panel. Create an
appropriately sized and located hole in the SPD enclosure.
Mount SPD. Connect to equipment using an approved wiring method,
including seals appropriate for the enclosure rating. Carefully reinstall
backplane or disconnect switch as appropriate.
Connect conductors as appropriate – short and straight as possible
(Note that Hi-Legs are Phase B)
Label or mark conductors as appropriate (neutral: white, ground:
green, energized: black, hi-leg: orange)
Make sure system is bonded per NEC® and is clear of hazards or faults
before energizing (N-G bonding not per NEC® will fail SPDs: #1 cause
of SPD failures)
Energize and confirm proper operation of indicators and/or options.

BREAKER
• Use closest breaker to SPD
• Locate SPD close to intended
breaker
• Keep Leads Short as Possible
• Avoid Sharp Bends
• Outdoor installation requires
appropriate weather sealing at nipple
(o-ring, sealing condulet, etc.)
