Maintenance
1. Working environment and storage means can affect the service term and reliability of
this product to some extent. Therefore, the product is not suitable for performance in the
following environment:
2. For long-term inaction, UPS (without batteries) should be kept in dry environment
with temperature ranging from -25-55
ć
. Before start-up, ambient temperature should be
brought back to 0 or above for a certain period of time (above 2 hours).
3. Keep good ventilation; otherwise, it will lead to internal temperature rise, shorten the
lifetime of the components and thus shorten the lifetime of the UPS.
4. For long-term inaction, the battery should be charged once every three moths in normal
temperature environment and once every two moths in high temperature environment
with no less than 10 hours; no-load discharge is not allowed, and the battery continuous
discharge time should not exceed 14 hours.
6. Do not cause battery positive and negative polarity short circuit otherwise electric shock
or inammation may occur.
A. Locations where temperature exceeds the maximum or goes below the minimum
temperature as required by technical specications or humidity is improper (temperature
range: 0-40
ć
; relative humidity range: 0-95%).
B. Locations where vibration and collision are constant;
C. Locations where metallic dusts
ˈ
corrosive substances as well as salts and
inammable gases are present.
