Key facts

  • On bypass: the load runs on mains power with no battery behind it[1]
  • Overload: the load is above the UPS rating[2]
  • Eaton red alarm light: call service[3]
  • Common root causes: batteries, fans, capacitors, overload, input events
  • Capacitors and fans: due around 7 years in Eaton power trains[4]

What Happens When You Call for Emergency UPS Repair in Toronto?

Protect the load, photograph the display and keep the event log: the first half hour is planned before the call is even made. On site, the technician reads the event log, checks input, output and bypass, and measures the battery string; a part on hand means the repair happens on the first visit.

What happens when you call for emergency UPS repair in Toronto? Symetrix Canada's emergency line runs around the clock, and the first half hour is already planned: protect the load, photograph the display, keep the event log, and get the UPS back behind your load before the next outage.

What should you do in the first half hour? First, check what is powering your equipment: the inverter, the battery, or bypass. Photograph the display before anyone touches a button, and do not reset repeatedly. A reset clears the message, not the cause. On bypass, the load runs on mains power with no battery behind it, so leave it there and let the visit find the fault. If the UPS is overloaded, shed the non-critical loads.

What do the alarms tell you? On APC Smart-UPS units, bypass means mains power only while the input stays within limits. On Delta's small N-series units, an overload transfers to bypass after a time, and an output short circuit shuts the UPS down with no output. On Eaton units, a red alarm lamp, or no green lamp, means call for service. And a swollen or hot battery clears the room.

What happens on site? The technician reads the event log, checks input, output and bypass, and measures the battery string. If the part is on hand, the repair happens on the first visit. If not, the UPS stays on maintenance bypass with your load supported, you get the lead time in writing, and the report states the fault, the cause and the parts replaced.

Emergencies do not keep office hours. Our technicians repair Eaton, Vertiv, Tripp Lite and more across Toronto and the GTA, around the clock. Reply and quote within 4 business hours. Call 1 (438) 800-0382. Find Symetrix Canada on the web.

The first half hour

  1. Check the load. Is the critical equipment still powered, and is it on the inverter, the battery or bypass?
  2. Photograph the display. Alarm codes, messages and the mode icons, before anyone touches a button.
  3. Do not reset or restart repeatedly. A reset clears the message, not the cause, and restarting a UPS that tripped on a fault can repeat it.
  4. If it is on battery, check that the generator started. With no generator, shut down the least critical systems first to stretch the runtime.
  5. If it is overloaded, unplug or shut down non-critical loads to bring it back under its rating [5].
  6. If it is on bypass, leave it there unless your site procedure says otherwise. The load has no battery protection until the UPS returns to normal.
  7. Keep people away from a swollen, hot or leaking battery and ventilate the room.
  8. Have ready: make, model, serial number, site access contact, and what changed recently.

What the alarms mean

Alarm or indicator What it means What to do
On bypass (APC Smart-UPS) Mains power to the load, only while input voltage and frequency stay in limits [1] Leave it; call for service
Overload (APC Smart-UPS) Connected equipment exceeds the UPS maximum rating [2] Shed non-critical load
Overload (Delta) After a limited time the UPS moves to bypass [6] Shed load before it transfers
Replace Battery (APC) Replace the battery immediately [7] Book a battery replacement
Battery replace (Delta) The batteries are weak [8] Expect short runtime; book replacement
Red alarm indicator (Eaton 93PS) An alarm is active, or normal operation has stopped [3] Call service
Output short circuit (Delta) The UPS shuts down with no output [9] Do not restart; call service

What happens on site

The technician reads the event log, checks input, output and bypass, measures the battery string and inspects fans, capacitors and connections. If the part is on hand, the repair is made on the first visit. If a part has to be ordered, the UPS is left on maintenance bypass with the load supported, and you get the lead time in writing.

The report states the fault found, its cause where it can be established, the parts replaced, the readings taken and what to plan next.

Common questions

What should I do if the UPS is on bypass?

Leave it there unless your site procedure says otherwise, note the alarms and call. On bypass the load runs on mains power with no battery protection [1], so the priority is getting the UPS back to normal before the next outage.

Should I reset a UPS alarm?

Not before photographing the display and saving the event log. The log is how the fault is found.

Can a UPS be repaired?

Most commercial and data-centre UPS faults are repairable: batteries, fans, capacitors, power modules, boards and contactors are replaceable parts. Repair stops making sense when parts are no longer supplied for the model, or the cost nears a replacement.

Is it worth repairing a small plug-in UPS?

Often not. For a single-phase plug-in unit, a new UPS can cost less than the repair. For three-phase and large single-phase units, repair is usually far cheaper than replacement.
