Installing an SPD that is improperly rated for the electrical system voltage could create a potentially hazardous
condition, resulting in injury or equipment damage.

Eaton SPD series products must be installed or replaced by a qualified electrician to avoid injury or equipment
damage.
Before installing an Eaton SPD Series unit, do the following:
• Verify that the area is clear of any dirt, debris or clutter that may hamper the installation process.
• Verify that there is enough space to install the SPD. See 2.3 Installation Procedures for dimensions.
• Confirm that all tools and equipment needed for the installation are available.
• Confirm that the system voltage and wiring configuration is the same as the SPD you are installing. Check
the voltage rating label on the side of the SPD.
Turn off the power supply before working in any electrical cabinet or on any circuit breaker panel. Failure to do
so could result in injury or death from electrical shock.
Do not use the SPD to carry or pass through ground to other devices or leads. Damage to the equipment may
result.
A poor ground, or grounding/bonding violations, could prevent the SPD from performing as specified

Eaton's SPD Series can be installed next to, above, or below any existing electrical enclosure.
The ideal mounting location for the Eaton SPD Series is as close as possible to the electrical enclosure. The
Eaton SPD Series should be mounted in such a way as to minimize any sharp bends in the wiring conduit.

1. Before mounting the SPD first determine the ideal location and ensure that the mounting surface is
adequate to support the weight of the SPD (See Figures Figure 3, Figure 4, Figure 5, Figure 6, and Figure 7
on for model weights). The SPD should be mounted as close as possible to the electrical enclosure and as
close as possible to the wiring connection point within the enclosure. This will ensure a minimum wire
length and maximum SPD performance.
