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.
2 Installation
2.1 Inspection
After unpacking the product, please inspect any damage that may have occurred
during 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 Authorization (RMA) acceptance from Preen.
2.2 User Preparation
In the beginning, the product must be connected to an appropriate power line input.
Then, since fans intelligently cool it, it must be installed in sufficient space for circulation of air. It should be used in an area where the ambient temperature does not ex-
ceed 40C.
2.3 Input Connection
The input terminals are located on the rear panel of the product (see Figure 2.1). The
input power cord must be rated at least for 85C. 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 2.1 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.

AFV-P Series User Manual
NOTICE
When output voltage contains DC composition, Terminal “L” of the output ter-
minals indicates the “+” terminal; terminal “N” of the output terminals indi-
cates the “-” terminal.
Installation of the power cord to the product must be done by a professional and in
accordance with local electrical codes.
Figure 2.1 Input terminals
2.4 Output Connection
The output terminals are located on the rear panel of the product (see Figure 2.2).
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 2.2 Output terminals
Figure 2.3 Output terminals to the load
10
AFV-P Series User Manual
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
voltage 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 terminal of the load. Because the sensing leads carry only a few millamperes, 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 in order 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 unconnected or become open-circuited during operation, the product will disable the output. The sensing leads must be a twisted pair to minimize the pickup of external
noise. The sensing leads need to be connected to the load as close as possible.

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 interruption of the protective ground will cause a potential shock
hazard that could result in personal injury.

1. Press the item repeatedly to enter into the page
which calibrates the output socket current (refer to Figure 4.19).
2. Connect the product with the current meter and the load with 5Ω and the rat-

but also provide several powerful functions to simulate all kinds of power line conditions and disturbance. Users can make the output change according to the setting
value step by step via the STEP feature (refer to Subsection 5.2), or make the output
change according to the setting slew rate via the RAMP feature (refer to Subsection
5.3), even make the output change according to the setting value for a specific period
of time via the TRANSIENT feature (refer to Subsection 5.4).
