·    Check for cleanliness; then clean or replace as needed

·    Check rectifier and inverter snubber circuit board for discoloration

·    Check power capacitors for swelling or leakage

·    Check capacitor vent caps extruded more than 1/8fans for proper operation

·    Lubricate and check bearings for abnormal condition, where possible

·    Record all meter readings and calibrate as necessary, where possible

·    Measure and record phase-to-phase input, output, bypass, and battery voltages and currents, where possible

·    Review alarm log/history for any irregular activity, where possible

·    Verify remote status panel operation

·    Measure and record harmonic-trap filter currents, where possible

·    Check the inverter and rectifier snubbers for discoloration or damaged wiring

·    Check all contacts to ensure secure connections

·    Provide a comprehensive inspection report, with recommendations within 7 to 10 business days

When choosing a partner for the preventative maintenance of your UPS System, pay special attention to the qualifications required of their technicians. It is true that not all technicians are created equal – for example, some technicians may have the intellect, but lack the practical hands-on experience to provide adequate maintenance services for your equipment.

At Facility Gateway Corporation, we believe in employing only the most dedicated technicians. Our technicians average twenty or more years of experience. They are factory trained, and work on all UPS makes and models from all manufacturers. Stationed across the nation, FGC technicians are always available at anytime in your local area. And at FGC, our promise to our clients is that our technicians will follow outlined Standard Operating Procedures 100% of the time.

Also included in our One-Time UPS System Preventative Maintenance Visit is a check-up for your UPS Systems’ battery. This includes:

·    Measure and record each cell terminal voltage (DC and AC)

·    Measure and record overall system DC voltage and current levels

·    Measure and record ambient room temperature

·    Measure and record temperature of all negative posts

·    Measure and record AC ripple voltage and current

·    Measure and record VDC and VAC of jar/cell (cell#1 + post to frame ground; frame ground to – post of last cell in string)

·    Check jar and cover for signs of leakage

·    Check for corrosion on terminal post and connector

·    Check general appearance and cleanliness of battery room and batteries

·    Review your company’s battery maintenance logs and add maintenance entry

·    Safety check: confirm proper warning/hazard labels

·    Safety check: confirm proper operational information, placards, and labeling

·    Safety check: check safety equipment and supplies for proper amount and location

·    Torque battery to manufacturer's specification(if connection resistance measures greater than 20% of average)

·    Clean and re-secure all battery terminals and jumper connections, as applicable (up to 20%)

·    Clean and neutralize jar and rack/cabinet, as applicable

·    Load test each jar or use equivalent device

·    Provide inspection report with recommendations to you within 7 to 10 business days
