Installation and Operation Manual 
Introduction
Thank you for choosing the APC SurgeArrest
®
 PM_3X Series “Brick” Surge Protective Device.
The APC non-modular Surge Protective Device (SPD) is a high-quality, high-energy surge attenuation system that has been designed 
to protect sensitive equipment from damaging transient voltage surges. Proper installation is imperative to maximize the surge 
suppressor’s effectiveness and performance.
This manual is to be used as a guide for installing the device. Read and understand all information contained in this manual prior to 
installation. The outlined procedures are not intended to supersede local or national electrical codes. Check all applicable electrical 
codes to assure compliance.
This device must be installed by qualified electrical personnel. The installer should follow the steps detailed in this manual to 
ensure proper installation. A copy of the installer’s invoice, detailing the installation of this device, is required in order to take 
advantage of the unit’s product warranty.
The SurgeArrest
®
 PM_3X Series product lines specify a parallel SPD designed for service entrance and downstream panelboard 
applications. These units provide replaceable “brick” (all included surge protections are encapsulated into a single “brick” module) 
surge protection and are available in 120 kA phase rating.
All APC products are extensively tested according to industry standards as set by IEEE C62.41 and C62.45 for Type 2 Applications.  
Type 2 applications are permanently connected to SPDs intended for installation on the load side of the service equipment overcurrent 
device; including SPDs at the branch panel.
Save this manual! It includes instructions regarding the product warranty and replacement parts.
Testing 
Any factory or on-site testing that exceeds the normal operating voltage, such as high-potential insulation testing or other tests where 
the suppression components will be subjected to voltages higher than their rated “turn on” voltage, must be run with the suppressor 
disconnected from the power source. For 4-wire devices, the neutral connection at the SPD must also be disconnected prior to 
performing high-potential testing and then reconnected upon completion of the test.
Failure to disconnect this surge suppression device and its associated suppression components during elevated voltage testing will 
result in damage to the suppression components and/or other electronic components.
