1. INTRODUCTION 1.1 THE APP60S SERVICE POWER SUPPLY The APP60S Service Power Supply is a portable device used to provide temporary power for Alpha AP Series standby power supplies and XP Series uninterruptible power supplies while they are being serviced. The APP60S can be used in either pole or ground-mount enclosures to provide signal processing equipment in Cable Television and Broadband LAN distribution systems with current-limited, regulated AC power.

2. APP60S 3.1 APP60S Installation and Power Module Removal 2.1 Ammeter The front panel ammeter displays output current flowing from the power module into the load. It is extremely useful in determining the status of the plant during maintenance and trouble-shooting. When there is no load at the output, the ammeter reads zero. When the meter reads above the rated output of the APP60S, such as 18 or 20 Amps, an overload or short circuit condition may exist in the load. 2.
3. INSTALLATION AND OPERATION 3.1 APP60S Installation and Power Module Removal POWER MODULES SHOULD BE SERVICED ONLY BY QUALIFIED PERSONNEL. POWER MODULES CONTAIN MORE THAN ONE LIVE CIRCUIT. EVEN THOUGH AC IS NOT PRESENT AT THE INPUT, IT MAY BE PRESENT AT THE OUTPUT. NOTE: Before powering down a module, always switch the battery breaker OFF (or remove the battery fuse) before removing AC, otherwise the module will transfer into inverter operation. Procedure 1.
