DANGER! HIGH VOLTAGE! DANGER! HOT SURFACE!
The VI Brick® AC Front End Evaluation Board contains exposed hazardous voltages.
These voltages are within the area marked by the hashed line on the board.
The VI Brick AC Front End Evaluation Board may be operated at surface temperatures
which may pose a thermal hazard to the operator. Because of the thermal and voltage
hazards, be careful not to touch any exposed surface unless the power is disconnected
and the evaluation board has been given sufficient time to cool. The evaluation board
is not intended for use in end item equipment.

Set Up
The Customer Evaluation Board should be set up as follows:

Note:

Care should be taken to avoid reversing polarities if connecting to the opposite (solder) side of

the board.

AC Input Connections (J01) DANGER! HIGH VOLTAGE!
J01, the screw terminal connector, is for connection of AC input to the AC-DC
converter evaluation board. The interconnect leads should be appropriate for the
current and voltage supplied to the board.
For single phase power, connect LINE to the pin marked L, NEUTRAL to the pin
marked N and earth ground to the pin marked EARTH. Corresponding wires in an IEC
cable are brown, blue, and yellow with a green stripe.
The board can be used with three phase power. Connect LINE1 to L and LINE2 to N.
Earth ground should still be connected to the EARTH terminal of J1.

+OUT, –OUT
There are several connections available on the VI Brick AC Front End Evaluation
Board. Table 1 lists the available connectors and their current rating. Do not exceed
the rating of the connector or the module.

Output bulk (electrolytic) capacitance must be attached across the output of the VI
Brick AC Front End Evaluation Board. It is recommended that the hold-up capacitor is
to be applied between H12 and H10 or H14 and H10. RTV adhesive should be used if
laying the capacitor on its side. Refer to table 1 from previous page for the
appropriate range of output capacitance.
