2.1
Before using this product, please read product introduction and instructions first, observe wiring marks,
and confirm input voltage in line with the product.
2.2
For a large voltage power supply, there are several wiring terminals on its output terminal. In addition,
the wiring terminals are internally connected (equal to one-channel power supply). Thus the output
terminal should be accessed in load balance.
2.3
When wiring, please cut off the input power supply.
2.4
The switch power supply is a heating element. Please install it in a ventilated and dust-proofing
environment so as to prolong power supply service life. No package for the switch power supply. No
use in a flammable or explosive gases or vapors (such as anesthetic) environment, or a humid
environment (such as outdoor).
2.5
Most of the power supply cabinet is heat sink. During installation, please enlarge the contact area
between the cabinet and the shelf so as to maximize heat dissipation. This may prolong power supply
service life.
2.6
Check the contact between installed screw and power board parts, and measure the insulating resistance
of the cabinet, input and output in order to prevent electric shock.
2.7
Before turning on the power after installation, please check the connection of every wiring terminal
again. Make sure that input and output, AC and DC, single-phase and multi-phase, positive pole and
negative pole, voltage value and current value, etc. are correct. Reversal and misconnection are not
allowed.
2.8
Once a faulty occurs in a power supply, please contact our company. Tell us the fault to figure out the
reason. Our company will repair or replace the product based on the actual situation.
2.9
Frequent turning on and off a power supply will shorten its service life.
