Vertiv Liebert APM and APM2 three-phase UPS explained
2:19. The Liebert APM2 is Vertiv's modular, transformer-free double-conversion three-phase UPS, from 10 to 150 kVA at 208/220 V and 20 to 600 kVA at 480/415 V.

0:00 What is the Liebert APM2? What is the Liebert APM2? It is Vertiv's modular, transformer-free double-conversion three-phase UPS, from 10 to 150 kVA at 208 or 220 volts, and 20 to 600 kVA at 480 or 415 volts.
0:18 What does modular mean here? What does modular mean here? Hot-swappable power modules, and Vertiv publishes a mean time to repair under half an hour. The converter design is three-level IGBT with hybrid silicon carbide.
0:30 Which batteries does it take? Which batteries does it take? Internal VRLA or lithium-ion batteries on the smaller frames, or external battery cabinets.
0:38 How efficient is it? How efficient is it? Vertiv publishes 97.5 percent peak in double conversion, up to 98.8 percent in Dynamic Online, and up to 99 percent in ECO mode, in the modes published for this family.
0:53 And the output? And the output? Unity power factor: kilowatts equal kVA, so the frame's rating is real power for IT load. A single unit scales to 600 kilowatts, and a parallel system of four units reaches 2.4 megawatts.
1:08 And the footprint? And the footprint? The 10 to 120 kVA frame packs power, maintenance bypass and battery into a 600 millimetre width, so a row-based site gets everything in one strip, and Vertiv claims up to about 55 percent footprint saving.
1:24 And the older APM? And the older APM? Vertiv still lists the 208 volt APM family; the international 380 to 415 volt versions are legacy. The APM2 is the newer platform covering the wider range, and Vertiv lists it as current in Canada, so a 208 volt APM site stays on a listed family.
1:46 Who is it for? Who is it for? Sites that want modular, transformer-free protection from a single rack row up to a mid-size data hall, in the 10 to 600 kVA range, at 208, 220, 480 or 415 volts. If you are sizing one, request a quote at threephaseups.ca.
Maintenance visit checklist
What does a maintenance visit check on a Liebert APM2?
2:05. On a Liebert APM2 the operator's part is the touchscreen and the front of the room: alarm text, the time, room conditions; the Silence button stops the sound but not the condition. The visit covers the wear parts and tests the battery settings the manual defines: a low pre-warning adjustable 2-60 minutes (5 default) and an end-of-discharge voltage of 1.60-1.85 V per cell on VRLA. Safety timings: battery terminals stay live after shutdown and the DC bus needs 30 minutes to discharge. Source: Vertiv's APM2 user manual SL-71948.

0:00 What does a maintenance visit check on a Liebert APM2? What is checked during a maintenance visit on a Vertiv Liebert APM2? The split: your part is read-only, from the touchscreen and the front, and everything inside the power cabinets belongs to a scheduled visit.
0:12 What is on you? What is on you? Read the alarm text on the touchscreen and note the time, and check the room conditions from the front. The Silence button stops the sound, but the message stays until the condition is corrected. Silencing is not clearing.
0:26 What does the visit look for? What does the visit look for? The wear parts, and Vertiv's own replacement table for them: fans with a life of not less than 7 years, replaced at five to six and inspected yearly; air filters with a life of 1-3 years, replaced at one to two.
0:42 What does that table say about batteries? What does that table say about batteries? A five-year-design VRLA battery is replaced at three to four years; a ten-year-design at 6-8 years. Vertiv's caveat: those are estimates, and other conditions need a service engineer's assessment.
0:57 What do you test between visits? What do you test between visits? That the battery low pre-warning lands where you set it: the manual makes it adjustable from 2-60 minutes, 5 minutes by default, with the end-of-discharge voltage settable from one point six zero to one point eight five volts per cell on sealed lead-acid batteries.
1:16 What are the safety timings? What are the safety timings? After any shutdown, the battery terminals still carry hazardous voltage, and the internal DC bus capacitors need 30 minutes to discharge.
1:26 And after a fault shutdown? And after a fault shutdown? Clear the cause shown by the alarm message first, then use Reset Fault and restart. If the shutdown came from overtemperature, the rectifier restarts by itself 5 minutes after the signal disappears.
1:40 What is the boundary? What is the boundary? Everything else, including breakers, power cabinets and batteries, is technician work. If a Liebert APM2 is due for a visit, request a quote at threephaseups.ca.
