7.3 Precautions
Although the S4K2UC has been designed and manufactured to ensure personal safety, improper use can result in electrical
shock or fire. To ensure safety, observe the following precautions:
♦
Turn off and unplug the S4K2UC before cleaning it
♦
Clean the UPS with a dry cloth—do not use liquid or aerosol cleaners
♦
Never block or insert any objects into the ventilation holes or other openings of the S4K2UC
♦
Do not place the S4K2UC power cord where it might be damaged
7.4 Checking UPS Status
SolaHD recommends checking the UPS operation status every six months.
♦
Check if the UPS is faulty: Is the Fault Indicator on? Is the UPS sounding an alarm?
♦
Check if the UPS is operating in Bypass Mode. Normally, the UPS operates in Normal Mode; if it is operating in
Bypass Mode, stop and contact your local SolaHD representative or SolaHD Technical Support.
♦
Check if the battery is discharging. When the utility input is normal, the battery should not discharge. If the UPS is
operating in Battery Mode, stop and contact your local SolaHD representative or SolaHD Technical Support.
7.5 Checking UPS Functions
NOTE:
UPS function check procedures may interrupt power supply to the connected load. Back up all critical load data
before conducting the UPS functions check.
SolaHD recommends checking the UPS functions once every six months.
Procedures are as follows:
1.
Press the Standby/Manual Bypass button to check whether the alarm and indicators are normal.
2.
Press the On/Alarm Silence/Manual Battery Test button to check again whether the indicators are on and the UPS is
operating normally.
3.
Press the On/Alarm Silence/Manual Battery Test button for 3 seconds after Inverter Mode; the UPS should initiate
battery self-test. Check to determine whether the battery is operating normally. If not, stop and contact your local
SolaHD representative or SolaHD Technical Support.
