ation, service, and repair of this product. Failure to comply with these precautions or
specific WARNINGS given elsewhere in this manual will violate safety standards of de-
sign, manufacture, and intended use of the product.
Preen assumes no liability for the customer‘s failure to comply with these require-
ments.
1) BEFORE APPLYING POWER
Verify that the product is set to match with the power line input.
2) PROTECTIVE GROUNDING
Make sure to connect the product to the protective ground to prevent an electric
shock before turning on the power.
3) NECESSITY OF PROTECTIVE GROUNDING
Never cut off the internal or external protective grounding wire, or disconnect
the wiring of protective grounding terminal. Doing so will cause a potential shock
hazard that may bring injury to a person.

5) DO NOT REMOVE THE COVER OF THE PRODUCT
Personnel who operate the product must not remove the cover of the product.
Component replacement and internal adjustment can be done only by qualified
service personnel.
WARNING
LETHAL VOLTAGES. The product can supply 440V peak at its output. DEATH on con-
tact may result if either the output terminals or the output circuits connected to the
output are touched when the product output is on.

2Installation
2.1 Inspection
After unpacking the product, please inspect any damage that may have occurred dur-
ing the shipment. Save all packing materials in case the product has to be returned one
day.
If any damage is found, please file a claim with the carrier immediately. Do not return
the product to the factory without obtaining the prior Return Merchandise Authoriza-
tion (RMA) acceptance from Preen.
2.2 User Preparation
Be sure the device is connected to the power line input that meets the specification.
The device must be installed in an air-circulated area, so that the fans built-in are able
to ventilate the heat generated by components properly. The ambient temperature
should be controlled within 40C.
2.2.1 Notice for Installation
1. The device must be installed on horizontal grounds and should be located near
the load so that the connection is as short as possible.
2. Leave sufficient space around the device for ventilation and maintenance (refer
to Figure 2.1). Do not block the cooling fan opening in case of internal tempera-
ture getting too high and having bad impact on product lifespan.
3. The device should be located in proper ventilation. The ambient temperature and
humidity should not be high. Stay away from liquid, flammable gases, corrosive
substances, heat sources, or direct sunlight. Keep the opening free from dust.
4. The operating environment should be free from dust, volatile organic compounds,
high salinity, or corrosive substance.
5. Do not operate the device outdoor.
6. Use correct cable selection and proper power distribution to ensure the safety of
the device and the users.

2.3 Input Connection
The input terminals are located on the rear panel of the product (see Figure 2.2). The
input power cord must be rated at least for 85C. The input power cord must have
rated current which is greater than or equal to the maximum input rated current of
the product.
See Figure 2.2 and do the following procedures step by step:
1. Remove the safety cover from the rare panel of the product.
2. Screw the power cord to the input terminals of the product as follows,
2.1 green or yellow wire to the terminal “G” of the input terminals;
2.2 white or blue wire to the terminal “N” of the input terminals; and
2.3 black or brown wire to the terminal “L” of the input terminals.
3. Slip the safety cover over the input terminals, and secure the cover with two
screws.
WARNING
Protective Grounding. To protect users, the wire connected to terminal “G” (that
is GND) must be connected to the earth ground. Under no circumstances shall this
product operated without an adequate protective grounding connection.
Installation of the power cord to the product must be done by a professional and in
accordance with local electrical codes.

2.4 Output Connection
The output terminals are located on the rear panel of the product (see Figure 2.3). The
terminals “N” and “L” of the output terminals are connected to the load. To match the
safety requirements, the safety cover for the output terminals must be fastened. The
wires to the load must be sufficiently large gauges, so they will not overheat while
carrying the output current.
Figure 2.3 Output terminals
Figure 2.4 Output terminals to the load

AFV-S Series High Performance Programmable AC Power Supply
13
2.5 Remote Sense Connection
The product supports remote sense function, which monitors the voltage at the load
instead of the output terminal of the product. It ensures the delivery of accurate volt-
age as programmed at the load by automatically compensating the output voltage
drop over the connecting cable.
Remove the iron chip from the terminals “SN” and “SL” of the remote sense connector
and connect the terminals of the remote sense connector to the corresponding termi-
nal of the load (see Figure 2.4 & 2.5). Because the sensing leads carry only a few
milliamperes, the sensing leads are much lighter than the load leads. The sensing leads
are part of the feedback path of the product, so they must be kept at a low resistance
to maintain the best performance. The sensing leads must be connected to the load
carefully so that they will not be open-circuited. If the sensing leads are left uncon-
nected or become open-circuited during operation, the product will disable the output.
The sensing leads must be a twisted pair to minimize the interference from external
noise. The sensing leads need to be connected to the load as closely as possible.

2.6 Power-on Procedures
WARNING
Before turning on the product, all protective grounding terminals, extension
cords, and devices connected to the product must be connected to a protective
ground. Any disconnection of the protective ground will cause a potential electric
shock hazard that could result in personal injury.
Apply power and press the power switch to turn on the product, then the touch
screen located on the front panel will light up and display the POWER-ON page shown
as below,
Figure 2.6 POWER-ON page
After displaying the POWER-ON page, the MAIN page is shown on the touch screen as
follows, and then users can input programming data or options by either pressing the
touch screen or turning the rotary knob.
