precautions.
Important Safety Instructions
■Ensure proper grounding. Before turning on the power supply, please make sure that the power supply
is reliably grounded to prevent electric shock.
■Single phase 220VAC input. Make sure the input wire meets the specified standards, and a protective
cover must be installed to prevent electric shock.
■Output cable connection. Make sure the output wire meets the specified standards, and a protective
cover must be installed to prevent electric shock.
■Do not open the instrument case. Operators are not allowed to open the shell of the power supply.
Non-professionals are not allowed to repair or adjust.
■Do not use in a hazardous or dangerous manner either alone or in conjunction with other equipment.
Operating in inflammable or explosive environment is strictly forbidden.

2.6 Installing
2.6.1 Preparation For Use
(1) Ensure the Power Supply is connected to the AC line input that meets the specification.
(2) The instrument must be installed in an area with good air circulation to avoid the internal temperature getting
too high.
(3) For indoor use only, ambient temperature 0°C to 40°C.
2.6.2 Requirements of Input Power
Please pay attention to the following items for FTP series power supply input connection:
①Single phase AC input: 190VAC~265VAC, 47~63Hz;
②Ensure reliable grounding;
③The AC power cord temperature resistance is greater than 85℃;
④Please refer to "Table 6-1 Recommended Wire Diameters for Cables" for the selection of input wire diameters
to avoid potential safety hazards due to thinner wire diameters.
----------------------------------------------------------------------------------------------------------------------------
1. To protect the operator, the wire connected to the GND terminal must be connected to
the earth. Under no circumstances shall this DC Power Supply be operated without an
adequate ground connection.
2. Installation of the power cord must be done by a professional and compliant with local
electrical codes.
----------------------------------------------------------------------------------------------------------------------------
2.6.3 Power ON Self Check
When powered on, the power supply will conduct self check, the check process and results will be displayed on
the screen, such as below:
Figure 2-5 FTP Power ON Self Check
The power supply will enter MAIN PAGE if all checking results are OK.
If there is FAULT during power supply power on self check, please contact authorized Faithtech agent or Faithtech
after-sale service.

2.7 Connection
2.7.1 Input Connection
The user connects the three-phase wire and the ground wire to the power supply input terminal as shown in
Figure 2-6. For the size of the wire diameter, please refer to "Table 6-1 Recommended Wire Diameter for Cables".
Figure 2-6 FTP Power supply Input Connection
----------------------------------------------------------------------------------------------------------------------------
1. To protect the operator, the wire connected to the GND terminal must be connected to
the earth. Under no circumstances shall this DC Power Supply be operated without an
adequate ground connection.
2. Installation of the power cord must be done by a professional and compliant with local
electrical codes.
----------------------------------------------------------------------------------------------------------------------------
2.7.2 Input Connection for Multiple Power Supplies
If multiple models are connected to the grid, it is recommended to distribute the access points in a balanced
manner as shown in the figure below.
Figure 2-7 Input Connection of multiple FTP Models
