Introduction

Thank you for choosing the surgeassureTM S50A Residential
Surge Protective Device.

Save this manual! It includes instructions for obtaining
warranty service and for returning a defective device.

Please read and understand all information in this manual
prior to installation. The procedures contained herein
are not intended to supersede local or national electrical
codes. Check all applicable electrical codes to ensure
compliance. In all instances, local and national electrical
code requirements are to be followed.

This manual provides instructions for installing the S50A
Surge Protective Device (SPD). The S50A SPD (Figure

1) can be mounted three ways. The preferred way is to
mount the SPD directly to the outside of the electrical
panel equipment using the pipe nipple on the body of the
SPD. Other options include standard 35mm DIN-rail (not

included) or via the attached L-bracket for standard at

mounting surface. Some of these methods require the
use of additional conduit and hardware (not provided).
See Figure 4 for further information on mounting methods.

The S50A provides protection from damaging transient
voltage surges and spikes. Proper installation is imperative
to maximize the effectiveness and overall performance of
this device. This device must be installed by a licensed
electrician. The electrician should follow the steps outlined
in this manual to insure proper installation.

Note: surgeassureTM products are extensively tested to
industry standards as set by ANSI/IEEE C62.41.1-2002,
C62.41.2-2002, and C62.45-2002. The S50A is listed to the
most recent edition of UL 1449 Third Edition (Sept 2009).

During installation into an electrical system, the S50A must
NOT be energized until the electrical system is installed,
inspected and tested. All conductors must be connected
and functional, including neutral (if required).

Failure to follow the guidelines in this manual can lead to
abnormally high voltage being applied to the SPD. This
may cause the S50A unit to become inoperative. The
warranty does not cover an incorrectly installed device.

Do not high potential test the electrical system with the SPD
connected. Failure to disconnect the SPD during elevated
voltage testing will result in damage to the suppression
components and/or other electronic components (see
Safety Information).
