Electrical Safety • • • • • • Lethal voltages are present within the power supply and electrical boxes. Never assume that an electrical connection or conductor is not energized. Check the circuit with a volt meter with respect to the grounded portion of the enclosure (both AC and DC) prior to any installation or removal procedure. Always use the buddy system when working under hazardous conditions. A licensed electrician is required to install permanently wired equipment.
1.0 Introduction UPE Series enclosures support distributed powering architectures in broadband applications. The power supply is located on the equipment shelf above the batteries for maximum convection cooling. Ideal for use in all climates, each enclosure comes with a removable, lockable door. Standard features include battery slide trays, high magnetic circuit breaker, duplex AC receptacle, service power inserter (SPI), and external coax raceway.

2.0 Installation 2.1 2.2 Site Considerations • The site must be planned so the enclosure receives 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.
2.0 Installation, continued 2.3 Enclosure Installation Follow the procedure below for attaching the enclosure to a pedestal support or precast pad. Tools and Materials Required: • Ratchet set with 6" (152.4mm) extension. • Vapor Barrier • Utility Knife CAUTION! 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.

2.0 Installation, continued 2.5 Enclosure Grounding Alpha recommends 5 ohm minimum ground resistance between enclosure and ground rods, in accordance with IEEE 1100-1999, Powering and Grounding Electronic Equipment. Alpha Technologies assumes no responsibility or liability for failure of the installer to comply with the requirements of applicable local and national codes. Where allowed, exothermic welding may be used as an alternative to Burndy clamps and connectors.
2.0 Installation, continued 2.6 Utility Power Connection Utility power enters the enclosure through the side or bottom of the UPE. The enclosure accepts a standard electrical fitting. The UPE Series can be equipped with an optional circuit breaker assembly located in the enclosure’s module compartment. CAUTION! Utility Power Connection procedure must ONLY be performed by qualified service personnel and in compliance with local electrical codes and common safety practices.
