PXL Series Installation
and Operation Manual
2.3 Minimize Installation Lead
Length
To ensure maximum performance and
best possible protection for connected
equipment, the PXL must be installed as
close to the panel/switchboard/switchgear
as possible. The wire length between the
PXL and installation breaker should be as
short as possible.
Note: For convenience, the PXL is
provided with two sets of terminal lugs to
permit left or right side installation
adjacent to the electrical equipment while
minimizing wiring length.
ONE SIDE ONLY OF THE SPD SHOULD
BE CONNECTED - AN SPD IS A
PARALLEL CONNECTION DEVICE,
ADDITIONAL LOADS SHOULD NOT BE
CONNECTED IN SERIES

2.4 Wiring
Turn OFF the power to the electrical
distribution equipment where the PXL
SPD is to be installed.
Install a branch circuit breaker to feed
PXL for ease of installation. The unit
contains UL and CSA approved fusing to
protect against short circuit fault
conditions within the device.
Overcurrent protection is required, (see
for required circuit breaker size).
Follow NEC, CEC as well as any other
applicable national or local codes when
connecting the PXL directly to the bus
bar.
30 ampere circuit breaker or fuses
with a rating of RK5-30 amperes must be
installed ahead of SPD for PXL
applications.
Table 1
Note:
The unit is provided with 8 knockout
holes - 3 on each side and 2 on the
bottom. Remove the knockout closest to
the intended lead-out form the
panelboard. Install metal conduit (rigid or
flexible) between the unit and the
electrical panel. Run wiring from the
panelboard to the PXL terminals, which
are labeled Phases A, B, C, Neutral and
Ground
(see T
recommended wire size).
Twist and bind together all leads.
Route the wires such that their overall
length is kept to a minimum. This reduces
line impedance and optimizes
performance.
Strip the ends of the wires and terminate
them in the panelboard. Ensure the use
of proper color codes and tighten all
connections. Green or green/yellow
(ground), white (neutral) red (hot), blue
(hot), black (hot).
Recheck all connections.
If remote monitoring is employed,
connect the Form C contacts to an alarm
or building monitoring system (such as an
addressable relay). These contact relays
will accept up to 220 VAC, 1A (see
).
: Form C relay contacts are “fail
safe” and only change state when power
is applied to the PXL, or if the unit is
damaged.
Switch the MAIN power to the ON
position. Switch the branch circuit breaker
supplying the SPD to the ON position.
Ensure all status indicator lights are ON
(see
Operating Features).
All installations must adhere to the
following torque limits regarding the SPD
connection to cable or bus. (

Prior to SPD energization, ensure that
the front cover is securely fastened.

2.2 Installation Recommendation
for PXL
Where to Install the PXL?
Service entrance applications(switch boards
and switchgear): The optimum location for
the PXL unit is on the load side of the main
breaker. If this is not possible, select the
next closest location. Minimize the lead
length between the suppressor and bus
bars (including the ground bus).
Panelboards applications: for optimum
performance, install the PXL adjacent to the
first breaker after the incoming lug/main
breaker. If this location is occupied, select
the next closest breaker. If no wall space is
available at the side of the panelboard,
locate the PXL directly above or bellow the
panel.
Remove the five screws from the front of
the unit, and lift out the entire front panel.
Mount the device to the wall using the
convenient holes in the back of the
container.
