1. INTRODUCTION 1.1 The APC (APL) Non-Standby Power Supply Product Description: Alpha APC (APL) Series non-standby power supplies provide conditioned power to signal amplifiers in Cable Television and Broadband distribution systems. The modular design, which consists of a baseplate, transformer assembly and enclosure cover, supplies the load with current-limited, regulated AC power that is free from disturbances caused by spikes, surges and other forms of power line transients.
1. INTRODUCTION 1.2 Operating Principle The Modular Transformer Assembly (MTA) contains a ferroresonant transformer, resonant circuit capacitor, and control panel with line input circuit breaker and output fuse assembly. Alpha APC (APL) Series non-standby power supplies utilize ferroresonant transformer technology to provide line conditioning and voltage regulation.
1. INTRODUCTION 1.3 Standard Features The APC (APL) Series non-standby power supplies are available in the following configurations: 1.3.1 APC (APL) 6008 Non-Standby Power Supply (120 VAC, 60 Hz Input) (8 Amp, 480 VA, 60 Volt Output); available in Pole, Rack, Wall, Shelf, or Pedestal-mount configurations. Includes: 8 Amp thermal input circuit breaker, 120 VAC output receptacle and 10 Amp output fuse. 1.3.

1. INTRODUCTION 1.4 Optional Features APC (APL) Series non-standby power supplies can also be equipped with the following options: 1.4.1 SIL-C (Status Indicator LED) The Status Indicator LED (red) indicates that the APC (APL) is supplying AC output to the load. The long-life LED pilot lamp can be viewed from outside the enclosure. As long as power is present at the modules output, the lamp remains ON.
1. INTRODUCTION 1.4 Optional Features, continued 1.4.6 GLK (Enclosure Locks) APC (APL) Pole Mount enclosures can be equipped with an optional security lock in situations where accessibility or tampering may be a problem. PM models come equipped with a security hole for installing a standard padlock (see figure 1.3.a).
2. INSTALLATION 2.1 Unpacking and Inspection To ensure operator safety: 1. Power supplies should be installed only by qualified personnel and always in accordance with applicable electrical codes. 2. Use a bucket truck or suitable climbing equipment, such as safety harness and spikes, whenever installing pole-mount installations. 2.1 Unpacking and Inspection Carefully remove the APC from its shipping container. Make sure that the following items have been included: 1. 2. 3.
2. INSTALLATION 2.2 Pole-mount Installations The APC- PM and APL-PM are designed to be mounted on wooden, steel, or concrete poles. When used with wooden poles, mounting bolts that go completely through the pole should be used. When used with concrete poles, an approved mounting strap should be used. Most codes require the base of the enclosure to be located at a minimum height from the ground. Always verify height restrictions before proceeding.

This option must be hard-wired into the rack-mount unit by means of quick-connect connectors. 1. 2. 3. 4. Remove the wing-nut from the screw on the LA-E mounting bracket. Position the LA-E as shown in Photo 2.10.5.d and secure using the same screw.
3. OPERATION 3.1 Start-up and Test Once utility and cable connections have been made, the APC or APL should be tested before placing it into service. Procedure: Photos; APC-3.1.a; APL-3.1.b 1. Before applying power, ensure that the AC LINE circuit breaker is in the OUT (OFF) position (the white portion of the stem will be visible). If it is not, depress the breaker button all the way until it resets. 2. Plug the APC’s power plug into the receptacle provided in the internal AC receptacle box.
3. OPERATION 3.2 Shutdown and MTA Removal The modular APC and APL Series non-standby power supplies are designed for easy component removal and replacement. The entire main transformer assembly (MTA) can be replaced or upgraded in a matter of minutes. CAUTION: USE HEAVY GLOVES WHEN HANDLING A POWER MODULE THAT HAS JUST BEEN TAKEN OUT OF SERVICE. THE FERRORESONANT TRANSFORMER GENERATES HEAT AND MAY CAUSE BURNS IF HANDLED WITH BARE HANDS. Procedure: 1.
