Like other types of large power equipment, the UPS and battery circuit breaker box/battery cabinet have high voltage inside.
Because the components with high voltage can be accessed only when the front door (which is locked) is opened, the risk of
contacting high voltage has been minimized. This equipment meets the IP20 standard, and other safety shields are provided
inside the equipment.
There will not be any danger when operating this equipment according to the general instructions and the steps
recommended in this manual.
User serviceable components
All the equipment maintenance and servicing procedures involving internal access need tools and should be carried out only
by trained personnel. The components that can only be accessed by opening the protective cover with tools/special key
cannot be maintained by the user.
Multiple power inputs
This UPS system receives power from more than one source. Disconnection of all AC source and the DC source is required
before servicing.
This UPS has several circuits that are energized with high AC as well as DC voltages. Check for voltage with both AC and DC
voltmeters before working within the UPS.
Battery voltage higher than 320Vdc
All the battery physical maintenance and servicing procedures need special tools and should be carried out only by trained
personnel.
Take special care when working with the batteries associated with this UPS. When the batteries are connected together, the
battery terminal voltage exceeds 320Vdc and is potentially lethal.
Battery manufacturers supply details of the necessary precautions to be observed in working on or in the vicinity of battery
strings. These precautions should be followed implicitly at all times. Particular 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 of the same electric parameters by
Beside the communication board is a static sensitive area, ESD-proof action is critical before contacting with this area.
This warning mark represents all the indications for human safety.
