Only fuses with the required rated current, voltage, and specified type (normal blow, time
delay, etc.) should be used. Do not use repaired fuses or short-circuited fuse holders. To do so
could cause a shock or fire hazard. Warning: Make sure to unplug the power cord before
replacing the fuse.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes.
DO NOT REMOVE THE COVER OF THE INSTRUMENT

Operating personnel must not remove the cover of the instrument. Only qualified service
personnel can perform component replacement and internal adjustment.

2.4.2 Input Line Connection
(1) The Power input terminal is located at the right of rear panel.
(2) The power line must be 85°C rated at least.
(3) The power cable specifications must be matched as current requirements in Table
2-1.
(4) execute the following steps to assemble it:
a. Remove the input terminal safety cover of DC Power Supply.
b. Scrape off the skin of power cable tip (the bare portion is about 1cm) and clamp
the O-terminal.
c. secure the DC power terminal and the O-terminal of power cable with a Phillips
screwdriver.
d. Lock the safety cover of DC input terminal to avoid electric shock.
ATTENTION
1. The input wire connected to the earth must be connected to the GND terminal of DC
power and make sure the input terminal is properly grounded.
2. Installation of the power cord must be done by a professional and compliant
WithOperation Standard.
3. Please select the input cable with suitable withstand voltage according to the power
grid used in different countries.
4. To avoid electrical shock, do not live line connection and make sure the input mains is
effectively disconnected before wiring.
2.5 RemoteCompensation Connection
This series of programmable DC power supply has remote automatic compensation
function. The purpose is to effectively compensate the line loss on the output line of the

product and ensure that the voltage output to the user terminal is the set voltage. The DC
Power Supply is able to compensate 0-5 voltage drop.
The remote compensation line has connected to the negative and positive output terminal
of DC power supply at the time of ex-factory. The user should remove the positive and
negative terminals connected to the DC power supply and connect it to the actual product
input terminal based on usage the during use. This can compensate for the line loss between
the DC power supply and the customer product input terminal. Be aware the correct polarity
when connecting. The diameter of input wire need to be greater than10AWG and must meet
the pressure requirements.
ATTENTION
1. The remote compensation line must be effectively connected, or it will cause no
output of the DC power protection or crash.
2. The polarity of remote compensation must be connected correctly.If the polarity is
connected reversely，it will cause DC powerprotection and prompt an error message
“SENSE FAULT”.
3.The voltage range of remote compensation is 0V to 5V.
2.6 Output Connection
The output connector of the HPS Series series is located in the upper left part of rear
panel. The output line should be connected according to the prompting polarity “+” and “-”,

（1）The output terminal is located on the upper left part of rear panel.
（2）The power line must be 85°C rated at least.
（3）Scrape off the skin of output cable tip (the bare portion is about 1cm) and clamp the
O-terminal. Secure the output terminal and output cable with a Phillips screwdriver.
ATTENTION
1.Do not touch the output terminal to avoid electric shock during the DC power supply
working.

2. The output line must meet the maximum output current of the productby at least
10%, and must meet the temperature and pressure requirements.
3. The output wires are best to be intertwined with each other to prevent external signal
interference.
