Battery Safety - Santak 3C3 EX 30KS User Manual

Electric Safety
1. Before electricity is switched on, make sure earthing is properly done and wire and
battery polarity are correctly connected.
2. Battery protection device must be configured with over-current breaker of rated
speci¿cations.
3. When UPS relocation or wire reconnection is necessary, AC and battery should be
switched off and UPS should be completely turned off, otherwise there might be a danger
of electric shock because output terminal might be still electri¿ed.
4. Please use Santak speci¿ed appendix devices and accessories.
5. Prior to connecting the power distribution system to the UPS, make sure the rated
quadrupole over-current breaker is installed to break off all the input lines and thus
prevent a risk of electric shock.

Battery Safety

1. Battery service lifetime will be shortened as ambient temperature rises. Replace
batteries periodically to guarantee normal UPS performance and suf¿cient back-up time.
2. Only personnel with proper expertise can carry out the maintenance of accumulator
batteries.Replacement of accumulator batteries requires a match of same type and model
with equal quantity.
3. As accumulator batteries may contain potential electric shock and short-circuit current
danger, to avoid accidents that might be thus resulted, the following warnings should be
observed during battery replacement:
A. Do not wear watches, rings or similar metallic items;
B. Use insulated tools;
C. Put on rubber shoes and gloves;
D. Do not place metallic tools or similar metallic parts on the batteries;
E. Switch off load connected to the batteries before dismantling battery connection
terminals.
4. Do not expose accumulator battery to fire in order to avoid possible explosion that
might endanger physical safety.
5. Non-professionals are not allowed to open or destroy accumulator batteries for
electrolytes in batteries contain strong acid and other dangerous substances which will
cause damages to both human skins and eyes. Should electrolytes come into any contact
with human body unintentionally, rinse with clean water and seek medical advice.
