Safety
SAVE THESE INSTRUCTIONS - This manual contains important instructions that should be
followed during installation and maintenance of the UPS.
Important Rules
(1) Please follow the Kronos UPS operating instructions to ensure safe and proper operation.
(2) When the UPS is being moved or operated, please ensure that the machine is standing
vertically. Do not shake or tip over the machine. Avoid heavy impact.
(3) Poor grounding will lead to unexpected current leakage. Please ensure that the AC power
input is properly grounded (PE Ground) before making any connections.
(4) Please make sure that the UPS is placed in an insulated environment before use and that
there is no risk of electrocution hazard to any personnel.
(5) Do not connect the neutral wire with the ground and make sure that the input voltage phasing
and conductor sizing is correct.
(6) Once the UPS has been switched on, if the UPS needs to be moved then it must be fully
switched off and fully discharged. If the UPS is not discharged, the UPS will switch to
battery power after grid power is disconnected and pose an electrocution hazard.
(7) Do not place any objects, liquid containers, or coverings on the UPS. Any liquid spilled onto
the UPS could potentially lead to internal damage or high risk of electrocution.
(8) Make sure that the battery specifications match the UPS requirements before connecting any
external batteries.
(9) For 30k/40k models: The over current protection for the external battery circuit is to be
provided by others.
(10) For 30k/40k models: The maximum available fault current from the battery supply is 15 KA
minimum. The dc voltage rating of the battery supply over current protection device must be
installed near the battery supply must have a minimum rating of 250 VDC.
(11) Follow the safety guidelines below before engaging in any testing that involves the battery.
a. Remove all metallic items such as rings, watches and jewelry before working on the
batteries.
b. Always wear eye protection and use insulated tools.
c. Do not open or damage the batteries. The toxic liquid inside will harm the skin and eyes.
d. Keep batteries away from fire to prevent explosion.
(12) A readily accessible disconnect device shall be incorporated external to the equipment.
(13) For 10-20k models:
-This UPS may be provided with maximum one extension battery packs
-External DC Circuit disconnect Device shall be provided by other.
-Before installing or servicing the equipment,identify and disconnect the UPS from the
AC mains and load. The UPS contains internal batteries and may present a shock hazard
even when disconnected from the AC input branch circuit (mains).
-Any wiring, maintenance service and battery replacement, must be performed or
supervised by personnel knowledgeable about batteries and the required precautions.
-When replacing batteries, replace with the same type and number of batteries or battery
packs.
-CAUTION: Do not dispose of batteries by burning them. The batteries may explode.

-CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin
and eyes, and may be toxic.
-CAUTION: A battery can present a risk of electrical shock and high short-circuit current
through conductive materials could cause severe burns. The following precautions should
Be observed when working on batteries:
Before installing or replacing the batteries, remove jewelry such as wristwatches and rings,
or other metal objects.
-When working on batteries should wear rubber gloves and boots. Also, must use tools
with insulated handles, and do not lay tools or metal parts on top of batteries.
Remove battery grounds during installation and maintenance to reduce likelihood of
shock. Remove the connection from ground if any part of the battery is determined to be
grounded.
Symbols
Always follow the instructions and warnings on the UPS.
WARNING！Refer to the operating instructions.
WARNING！High voltage inside.

NOTE
NOTE: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
WARNING
WARNING: This is a category C2 UPS product. In a residential environment, this
product may cause radio interference, in which case the user may be required to take
additional measures.
