DO NOT INSTALL DURING ACTIVE
STORM CONDITIONS.
Note: It is important to keep all connecting leads
as short as possible. Additionally, conductors
should be twisted together for as much of the wire
run as possible.
1.
Ensure power to the panelboard has been
removed.
2.
Remove the screws securing the outer
panelboard cover to the panelboard (see
Figure 1).
3.
If SPD has optional flush mount kit
(SPD4Flush) please follow instructions
provided with the SPD4Flush and then
proceed to #4 in this manual.
4.
Select the location where the SPD4home
will be mounted (should be based on the
internal configuration of the panelboard
and the physical surroundings outside the
panelboard). Note that the SPD4home’s
lead length must be minimized to achieve
maximum performance. Once the location
and threaded connection has been
determined, drill or punch an appropriate
size hole in the top, bottom or side surface of
the panelboard. The ideal mounting location
will also allow the SPD4home to be secured
to the wall or panel in addition to using a
chase nipple or short threaded pipe.
5.
Push the leads from the SPD4home through
the hole toward the inside of the panelboard.
Secure the SPD4home to the panelboard.
6.
If possible, to provide extra rigidity in the
installation, attach the SPD4home to the wall
or panel using installer supplied hardware.
7.
Trim the leads from the SPD4home as short
as possible, but still allowing the following
connections to be made (see Figure 1):
▪
Black wires go to the nearest free 20 Amp
2 pole circuit breaker. The phase of each
lead is marked with a white band and letter
designator (L1 or L2). Connect the SPD-
4home leads to the appropriate phases. (In
all installations, it is not critical which black
wire goes to the positions on the circuit
breaker.)
▪
Connect the white Neutral wire to the
neutral bar using a set screw (in some
applications, this connection may not be
required).
▪
Connect the green Ground wire to the
panelboard ground.
8.
Install the panelboard cover. Note:
Conducting dielectric and/or high
potential testing will cause internal
damage to the SPD4home unit. DO NOT
perform dielectric or high potential tests
with the phase or neutral SPD4home
wires connected.
9.
Apply power to the panelboard. The two
LEDs will illuminate on the SPD4home. If
any connected phase LED on the SPD4home
does not illuminate, remove power, check all
connections and test again. If any connected
phase LED still does not illuminate, contact
Siemens Technical Support 1-888-333-3545.
