6. MAINTENANCE
6.1. Maintenance intervals
Vertiv recommends that regular maintenance checks be carried out on-site by an authorized
customer service. The UPS informs the user when the normal service life of a fan has ended. A
replacement fan is recommended.
6.2. Disposal of batteries
When the useful life of the batteries has ended, they must be replaced by your Customer Service
representative. Exhausted accumulator batteries are classified as “harmful toxic waste” that must be
disposed of in the EU by a certified disposal specialist. Outside the EU, they must be disposed of in
accordance with the applicable regulations for the given country. The Customer service centre is fully
equipped to deal with such batteries in accordance with regulations and with full respect for the
environment.
The typical useful life of the battery is 3 to 5 years at 25°C ambient temperature. However, useful life
also depends on the frequency and duration of line power failures.
6.3. Service addresses
On site service is available worldwide. Service telephone and fax numbers can be found on the last
page of this manual.
6.4. Decommissioning
6.4.1. Taking out of service
N.B.
Switch to Service Bypass
• Switch the UPS to Maintenance Bypass operation (see para 5.7.3. on page
81
)
N.B.
Disconnect the batteries
• Open the battery isolator or battery switch if other external batteries are used.
• Before continuing work, measure the voltage on the battery terminals and on the line power input,
and wait until these have dropped to 0V; or wait at least 5 min. Failure to do so may cause severe
electrical shock and possibly death.
The UPS is now in the maintenance Bypass operating mode. The only voltage present is at the line
power and load terminals. Qualified personnel may now carry out maintenance work while taking the
corresponding safety measures.
N.B.
Disconnect line power
If the loads no longer need power, you may open the external line power separation device for the UPS.
