Eaton UPS service in Toronto

Symetrix Canada is not the manufacturer of Eaton equipment. For a unit under warranty, check the warranty terms with the manufacturer first.

We maintain and repair Eaton and Powerware UPS systems in Toronto and the GTA, from 9155 towers to multi-module Power Xpert 9395 systems: preventive maintenance, battery strings, fans and capacitors, emergency repair. For each model, Eaton publishes two separate dates: when it stopped selling it, and when full parts and labour support ends.

Sold and serviced are two different dates

Eaton’s catalogue says whether a model is still sold. Its end-of-service-life table says how long Eaton supports it: Active means all parts and labour [4], and Mature means best efforts, with parts possibly limited and replacement recommended [24]. So a discontinued 9390 is still in Active service until 2027, and a 9355 that is still sold already has its best-efforts year. Plan repair or replacement from both dates.

Eaton’s maintenance schedule

Eaton’s 91PS/93PS guide splits the work. The site team checks every day that the air intakes and the exhaust are clear [25]. Every month, it washes or replaces the optional air filters and writes the results in a service log [26]. Service personnel inspect for overheating, with attention to bolted connections, which must be re-torqued periodically [27].

What we check on an Eaton unit

  • The event log, from the front panel or the network card, before any reset
  • Each battery block’s voltage, internal resistance and temperature against its baseline [28]
  • Bolted connections for heat, then torque with the equipment safely isolated
  • Fan noise and airflow, capacitor condition, and the age of both
  • Energy Saver System settings on models that offer it, such as the 93PM [11]
  • The transfer to bypass and back, in your change window

Common questions

Who services Eaton UPS systems in Toronto?

We maintain and repair Eaton and Powerware UPS systems across Toronto and the GTA, from single 9355 towers to multi-module 9395 systems.

How long does an Eaton UPS last?

The frame outlasts several battery strings. Eaton gives lead-acid UPS batteries 3 to 5 years [29], and recommends replacing power-train capacitors around 7 years of operation [1]. Full support runs until the model's best-efforts year; for the 9355 that is 2033 [9].

How do I reset an Eaton UPS?

Follow the reset procedure in your model's user guide, after saving the event log. A reset clears the alarm, not its cause. If the red alarm indicator stays lit, call service [30].

Is the Eaton 9390 still supported?

It is no longer sold, and Eaton names the 93PM as comparable [14]. Eaton keeps it in Active service until best efforts begin in 2027 at 208 V and 2028 at 480 V [15].

Do you service Powerware units?

Yes. Eaton's service table still files the 9355 under its Powerware line [9], and older Powerware three-phase models get the same visit as current Eaton ones.
