9.1

Maintenance

A UPS system, like other electrical equipment, needs periodic preventive maintenance.

A regular maintenance check of your installation guarantees higher reliability of your safe power supply.

ABB recommends to perform the first service within 12 months from the commissioning date or within 18 months from delivery date.

Subsequent services to perform every 12 months .

Preventive maintenance work on the UPS can be done only by an ABB Service Technician.

We therefore recommend you sign a Maintenance and Service contract with the local ABB Service Center organization.

9.1.1

Service check

If this lamp lights up during normal operation, the Unit has not been serviced for the last 20,000 hours by an ABB

Service Technician .

Some components of the UPS which need periodic maintenance, if not replaced, could cause a reliability reduction of the supply system.

We highly recommend that you contact your ABB Service Center for preventive maintenance work.

Note!

Never ignore a Service Check alarm!

Failure to perform mandatory preventative maintenance on components documented in the UPS product manual may result in thermal damage to the equipment, its surroundings and an increased risk of personnel injury.

Refer to Section 9.1.2 to 9.1.6 for this important detail.

9.1.2

Fans and ventilation

We recommend a periodic cleaning of the ventilation channels and grids on the UPS system, in order to guarantee proper air circulation in the Unit and in the Battery.

The fans eventually wear out and must be substituted when a UPS alarm is triggered, in order to ensure the reliability of the UPS.

9.1.3

Other components with limited lifetime

Various components, such as the DC and AC filter capacitors and the lithium Battery on the “Control board”

(memory saving), must be systematically replaced in order to maintain the UPS’S reliability.

The substitution of these components is Signaled by a UPS alarm going off.
