MAINTENANCE
The S4K
2U
UPS requires very little maintenance. The batteries
are valve-regulated, nonspillable, flame retardant, lead acid, and should
be kept charged to obtain their designed life. The UPS continuously
charges the batteries when connected to the utility supply.
When storing the UPS for any length of time, it is recommended to plug
the UPS in for at least 24 hours every four to six months to ensure full
recharge of the batteries.
The S4K
2U
UPS is designed to allow the user to safely replace the
internal batteries. Read the safety cautions before proceeding. Contact
your local distributor or Sola/Hevi-Duty representative to obtain the
appropriate replacement battery kit part number and pricing.
