Installation Instructions:
FirstSurge™ is a Type 2 SPD. It is suitable for use downstream
of the service disconnect.
Pre-Plan your installation. You need to accomplish the
following:
• Meet all National and Local codes (NEC®Article 285 and UL
1449 address SPDs).
• Conrm System voltage to SPD voltage (120V SPD will fail
instantly on 240V, 277V, etc.).
• Mount SPD as close to panel or equipment as possible to
keep leads short. (long leads hurt performance).
• Ensure leads are as short and straight as possible,
including neutral and ground. Use a breaker position that
is close to the SPD and the panel’s neutral and ground.
• Recommended breaker size is 20A.
• Make sure system is grounded per NEC®and clear of faults
before energizing SPD. (inadvertent system problem may
fail SPD).
• Never Hi-Pot test Any SPD. (will prematurely fail SPD).
1. Use voltmeter to check voltages and ensure correct SPD.
See Data Sheet for specs and wire-outs.
2. Determine Mounting location – weather resistant
equipment may be required.
3. If SPD has optional Flush Mount Kit, pre-plan its installation.
See Figure 3. (If ush mounting, be careful to not drop SPD
into wall).
4. Remove power from panel/source. Conrm panel/source is
deenergized.
5. Identify breaker location and SPD location. Position SPD
such that LEDs are best visible.
If Flush Mount Kit was ordered, follow Flush Mount
instructions and then proceed at #6.
6. Mount SPD – weather resistant applications require
additional sealing, etc. (not included)
-Remove an appropriately sized knockout from panel.
-Connect conductors as appropriate – short and straight
as possible.
7. Label or mark conductors as appropriate (neutral: white,
ground: green, energized: black).
8. 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).
9. Energize and conrm proper operation of green LED
indicators. If any connected phase LED does not illuminate,
remove power, check all connections and test again. If
any connected phase LED still does not illuminate, contact
Siemens Technical Support at: 1-888-333-3545.
10.The SPD is equipped with an audible alarm which will
sound in the event of an alarm condition. This indicates a
problem with the SPD which requires further evaluation.
There is no test or silence switch. De-energizing the SPD
will silence the alarm.

• 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 (gasket, sealing conduit, etc.)
• Rotate FirstSurge™ such that
LED indicator is most visible
