Preface Battery Safety Notes Lead-acid batteries contain dangerous voltages, currents and corrosive material. Battery installation, maintenance, service and replacement must be performed by authorized personnel only. Chemical Hazards NOTE: Any gelled or liquid emissions from a Valve-Regulated lead-acid (VRLA) battery contain dilute sulfuric acid, which is harmful to the skin and eyes. Emissions are electrolytic, which are electrically conductive and corrosive.
Preface Important Installation Notes The system must be installed ONLY by qualified service personnel. Consult local utility codes for additional cabinet grounding and utility requirements. ALPHA TECHNOLOGIES is not responsible for broken welds or other damage to the cabinet caused by improper installation. All dimensions are given in inches. For further information regarding this installation, contact ALPHA TECHNOLOGIES or your nearest ALPHA representative.
1. Pre-Installation 1.1 Site considerations The site must be planned so that the enclosure will receive good air flow. If possible, in areas of extreme heat, it is best to position the enclosure so that it will be shaded from the afternoon sun. If no shade is available, a factory installed fan kit is highly recommended. In areas of prevailing winds, it is best that the enclosure be located so that the sides of the cabinet face the winds instead of the doors.

1. Pre-Installation 1.4 Enclosure Grounding In order to provide a ready, reliable source of backup power it is necessary to establish a grounding system that not only provides for the safety of the service personnel responsible for its operation and maintenance, but also facilitates the proper operation and protection of the equipment within the network. Such a grounding system will provide protection with respect to operator safety, system communication, and equipment protection.
1. Pre-Installation 1.4 Enclosure Grounding NOTE: Alpha Technologies recommends using the grounding method illustrated below. The grounding method for a particular site will be dependant upon soil type, available space, local codes, NEC (National Electric Code), and other site-specific characteristics. It is the responsibility of the installer to ensure the requirements of all applicable national and local codes are met.
2. Installation 2.1 Enclosure Protection Alpha Technologies, Inc. cannot anticipate all of the ways a vehicle may potentially threaten an installed system or the specific type of protection that is appropriate for a particular location. The determination of the threat to the equipment and the means of protection are the responsibility of the end user of the equipment and the authority having jurisdiction.
2. Installation 2.2 Transportation and Lifting A safe means of transportation to the site and a safe procedure for unloading the enclosure is necessary. At least two installation personnel are required to place the enclosures on the pad. Installation team must assess the transport path for all obstructions. An obstruction free path should be selected for transport. Use safe lifting practices.
2. Installation 2.3 Enclosure Installation 2.3.1 Attaching enclosure to the Pedestal Support or Pad Tools Required: Ratchet set with 6” extension. Vapor Barrier Utility Knife Procedure: NOTE: 031-178-C0-001 Rev. A A 25+ year continuous vapor barrier must be used between the enclosure and pad to prevent moisture ingress and possible corrosion caused by metal to concrete contact. The vapor barrier material (such as 30 lb.
