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 flat

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:

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).
