? Are You UPSet ?

Luckily, my good client accepted my good advice to allow me to do a service of four of his UPS units plotted at the corners of his large North Carolina county. His thrifty nature chided me into doing all in a single day at a nominal fee, "cuz I was just passin' thru from Virginia." I honestly had slobbery visions of a gratis barbeque dinner topping off the day, as a dozen of his back-slapping crewmen all joked about fishing, hunting, and loose expense accounts. Instead, I was met by my familiar lunch partner with half a cold gas station calzone. The day was spent knee crawling and stretching to record measurements. For the first two Best Ferrups UPS systems, dust bunnies were the devil and a few volts calibrated ensured longevity. Tightened bolts, metered temps and checked for alarms.

Two more units to go and I am on my way to surprise my wife in Jacksonville, albeit the taste of she crab soup still lingered on my tongue. As my preventative maintenance sessions are more than thorough, I apologize to my client for my extensive use of his time as guide. He nods a humble appreciation for my record keeping and seems to take my recommendations seriously. I hand him a football size oval of plastic wrap which had somehow situated itself over the main fan guard cooling the heatsink of a 10KVA unit.

"I guess that could have become a problem," he drawls.

"Yes," I agree, "Power systems like their cooling. I expect this kind of crap to accumulate since ya'll have made this room storage for files and ... starter fluid ... 2-cycle oil .... and what the Hell is this? Propane tanks?"

"I guess we ought to do something about that," is murmured under a thick mustache.

This is commonplace. Battery backup equipment is relegated to an electrical room. That's OK, but that room is also home for some fat-daddy transformer installed right after WWII. The room is hot, but access is restricted. I'll take it! (My first apartment overlooked a swamp... it was smelly, but secluded, and I loved it.)

Our Carolina gentleman, a director, has many other duties and he hands me over to an older fellow who is still senior, and, therefore, first in line to (WAIT FOR IT!) OVERTIME. We are at the county's west perimeter and we are boxing to its east and lastly its south site. It was a perfect line-up that will leave me 30 minutes south on I-95. After 15 minutes of eating Chevy 1500 fumes I was deposited behind my new guide on a slather clay road. We bounced over an old tobacco field to finally roll onto the gravel pad spread beside the county's cell tower. It's time to work.

This Best Ferrups 4.3KVA is old. I mean FD series old, but the sucker is still humming; and according to the senior maintenance man, it was not a problem unit. Humming she was, as one fan was stuck tight. She was hot enough to grill cheese (yes I was getting hungry again). "No problem, I'm sure I have a 230V fan for her"......... no. I was scheduled to inspect three 10KVA to 18KVA units, and I am unprepared. If this fan is only dumping heat into the working unit, then there is no harm in yanking one (1) lead. So that's how we left it. Cooler, but not in shape. I chuckle as I note the wide calibration change I had to make, yet she hummed. So tough: so dirty.
