1.0 Important Safety InStructIonS
Thank you for selecting the S3K Series Uninterruptible Power System (UPS).
This manual contains important safety instructions that should be followed during
the installation and operation of your UPS. Please read all safety, installation and
operating instructions before attempting to install or operate the UPS. Please
adhere to all warnings on the unit and in this manual during installation and
operation.
1.1 SAFETY PRECAUTIONS—SAVE THESE INSTRUCTIONS
WARNING: The UPS is intended for installation in a controlled environment.
WARNING (Fuses): To reduce the risk of re, replace only with the same type
and rating of fuse.
CAUTION: To reduce the risk of re, connect only to a circuit provided with 20
amperes maximum branch circuit overcurrent protection in accordance with the
National Electric Code, ANSI/NFPA 70.
CAUTION (UPS with Internal Batteries): Risk of electric shock! Hazardous live
parts inside this unit are energized from the battery supply, even when the input
ac power is disconnected.
CAUTION (No User-serviceable Parts): Risk of electric shock! Do not remove
the cover—no user-seviceable parts inside. Please refer all repairs to a qualied
service technician.
CAUTION: Risk of electric shock! Disconnect the UPS from the mains supply
before installing a computer interface signal cable. Reconnect the power cord
only after signaling interconnections are made.
CAUTION (Non-isolated Battery Supply): Risk of electric shock! The battery
circuit is not isolated from the ac input. Hazardous voltage may exist between the
battery terminals and the ground; test before touching.
CAUTION: Servicing of batteries should be performed or supervised by
personnel knowledgeable in batteries and the required precautions. Keep
unauthorized personnel away from the batteries.
CAUTION: A battery can present a risk of electric shock and high-short circuit
current. The following precautions should be observed when working on
batteries:
• Remove watches, rings or other metal objects.
• Use tools with insulated handles.
CAUTION: Do not open or mutilate the battery. Released electrolyte is harmful to
the skin and eyes and may be toxic.
CAUTION: Do not dispose of batteries in a re—they may explode.
CAUTION: When replacing batteries, replace with the same number and type.
