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.
