General safety precautions (For users)
Like other types of large power equipment, the UPS and battery circuit breaker box/battery cabinet contain high voltages.
This equipment meets the IP20 standard, and other safety panels are fitted inside the equipment.
The UPS may be operated in complete safety, provided the general instructions and the steps recommended in this manual
are followed.
Multiple power inputs (For users)
This UPS system receives power from more than one source. All DC and AC power sources must be disconnected before
servicing.
This UPS includes several circuits that are energized by high AC as well as DC voltages. Check for voltage with both AC and
DC voltmeters before working inside the UPS.
User serviceable components (For service personnel)
All equipment maintenance and servicing procedures involving internal access require the use of a tool and should be carried
out by trained personnel only. There are no user-serviceable parts behind the covers that require a /key for removal.
Battery voltage: 320Vdc - 540Vdc (For service personnel)
All battery maintenance and servicing procedures require the use of tools and should be carried out by trained personnel only.
Take special care when working with the batteries associated with this UPS. When connected together, the battery terminal
voltage will exceed 320Vdc and is potentially lethal.
Battery manufacturers supply details of the necessary precautions to be observed when working on, or in the vicinity of, a
large bank of battery cells. These precautions should be followed scrupulously at all times. Special attention should be paid to
the recommendations concerning local environmental conditions and the provision of protective clothing, first aid and fire-
fighting facilities.
Warning
When the internal fuse of the UPS is damaged, it must be replaced with fuse having the same electric parameters by qualified
personnel.
Important
The area housing the communication board contains static sensitive components, therefore it is necessary to adopt all the
appropriate ESD-proof measures before accessing this area.
Warning
In order to satisfy the conditional short circuit current rating, Icc at 10kA symmetrical rms, the specified upstream breakers
must comply with an IEC 60947 series standard.
