1.4 Safety and ESD Notes
EXERCISE CAUTION WHEN LIVE AC VOLTAGES ARE PRESENT!
Do not connect test equipment, ICE emulators or external development boards
directly to the MAX78630+PPM hardware. Damage to the MAX78630+PPM and
external equipment will occur due to the MAX78630+PPM’s “high side” reference
topology. The MAX78630+PPM’s V3P3 (i.e., “high side”) is connected directly to
Neutral (Earth Ground) or Line Voltage, creating a ground reference disparity with
any properly grounded external equipment.
The board compone nts and firmware settings are designed to operate with the following nominal AC electrical
ranges:
Voltage Current Line Frequency
10-400V AC 10mA – 50A 46-64Hz
The maximum current is determin ed by the current t ransformer (CT) t hat is provided with t his EV kit:
CR Magnetics model no. CR8449-2500-N.
1.5 Testing the MAX78630+PPM EV Board Prior to Shipping
Before every EV kit is shipped, the board (and sensors) undergoes a single-load point calibration using precise
energy source equipment. The device temperature is also calibrated at the same time. Results printed out on
paper and included with the EV kit.
Note that the board is calibrated using the marked CTs included with the kit. Therefore, CT1 should be
connected to I1, CT2 to I2, and CT3 to I3.

2 Installation
2.1 USB Driver Installat ion
This EV kit includes an isolated USB interface for serial communications with a PC. The FTDI USB controller
IC FT2232 performs the USB functions. The FTDI Windows driver presents a virtual COM port for enabling
serial communications. The FTDI Windows driv er is a certified driver for Windows XP and Windows 7.
Upon attaching the MAX78630+PPM EV board to the PC, the Found New Hardware Wizard automatically
launches and installs the appropriate driver files. If your PC does not find the FTDI driver files on its local hard
disk drive, locate and reference the FTDI USB Driver and Utilities subdirectory on the CD. The FT2232
controller is powered from the USB cable and is active even when no AC power is applied to the
MAX78630+PPM EV kit.
Note: If an older FTDI driver has been previously install ed, it is recommended to remove the older version
before installing this newer FTDI driver. Execute the ftdiClean.exe utility from the FTDI US B Driver and
Utilities subdirectory.
For FTDI driver support on other operating system s, refer to the FTDI website at www.ftdichip.com.
2.1.1 Confirm COM Port Mapping
• Launch the Control Panel and click on the System icon.
• The System Properties screen appear s. Cli ck on the Hardware tab. Click on Dev ice Manager. Under
Ports (COM & LPT), look for t he USB Serial Port assignment.
• Take note of the CO M port assignment f or the USB Serial Port.
2.1.2 FTDI COM Port Trouble Shooting
If the FTDI device driver did not install properly, there would be no assigned COM port number for the FTDI
controller. Re peat the USB Driver Installation, see Section 2.1.
Microsoft Windows may associate a Ball Point device to the FTDI USB controller. When this occurs a FTDI
device COM port assignment is available via HyperTerminal but there is no communications data. Verify if a
Ball Point device has been added to the “Human Interface Devices” via the Device manager. See Sec tio n 2.1.1
for access to the Device Manager. If a Ball Point device exists, delete it and unplug and replug the EV kit’s
USB cable.
Two sequential COM
ports are associat ed
with the kit. Use the
second COM port
Port numbers may
differ on each P C.

2.2 Powering the EV Kit Board
The MAX78630+PPM EV board is normally powered through the USB port (J21).If power needs to be supplied
from a different source, a 5V DC can be appli ed to the connector J16; see Table 16 for the pin as signm ent.
When the MAX78630+PPM EV board is powered through via USB, the same cable also provides the
communicati ons li nk between the host PC and the MA X 78630+PPM EV board.
2.3 Basic Connection Setup
This section shows examples of basic connections between the MAX78630+PPM EV board and external
equipment. Additional connection examples can be seen in the MAX78630+PPM IC data sheet. Note that this
board does not directly support voltage transformers (VT) and provides a shunt resistor as alternative to the
current transform er on phase C.
The following examples are only a subset of all possible measurement configurations. Refer to the
MAX78630+PPM IC data sheet for configurati ons and system connection diagrams.
2.3.1 Wye-Connected or 3V Delta-Connected Three-Phase Systems
For Wye-connected systems, all three-phase (Line-to-Neutral) voltages are measured. The Neutral line is the
reference for all voltages (V3P3A). Jumper J11 must be in position 2-3 (3V Wye/Delta). It is also possible to
directly measure all three voltages in a Delta configuration. In that case, the Neutral is not accessible and the
MAX78630+PPM EV board is at a virtual cente r potential.

2.3.3 Neutral Current Measurement Considerations
It is possible, in certain W ye configurations to measure the current in the neutral c onductor via a shunt resistor,
therefore replacing the third phase current measurement. This function is enabled by setting jumper J15 to
position 2-3. The MAX78630+PPM EV board then connects the shunt voltage to input AIC of the MAX78630.
IC (J41) is not m easured in this case.
