§
Risk of electrical shock and energy hazard. All failure should be examined
by a qualified technician. Please do not remove the case of the power
supply by yourself!
§
Please do not install power supplies in places with high moisture or near
the water.
§
Please do not install power supplies in places with high ambient
temperature or near fire source. The maximum ambient temperature
please refer to their specifications.
§
Output current and output wattage must not exceed the rated values on
specifications.
§
The ground(FG) must be connected to earth ground.
§
The protective earthing is used as a safeguard, the instructions shall
require connection of the equipment protective earthing conductor to the
installation protective earthing conductor (for example, by means of a
power cord connected to a socket-outlet with earthing connection).
§
Notices for battery application
. Make sure charging voltage and current meet battery's specification. a
b. Refrain from connecting new and old batteries in series.
c. The cables between power supply and battery should be kept as short as
possible to prevent excessive voltage drop (suggested cable length:
50cm ~1000cm). Too much voltage drop will lead to longer charging
period.
d. The power supply is suitable for lead-acid batteries (flooded water type,
gel colloid type, AGM adsorption glass fibber ) or lithium batteries …etc
(lithium ion, lithium manganese, lithium ternary...etc).
