1. 50-Pin Ribbon Cable Connectors: Ribbon cables attach here for easy
connection of adapter boards to the data acquisition board. The two connectors
on the left are for panelboard 1; the two on the right are for panelboard 2.
Note: Connect Adapter Boards A and B to the correct ribbon cable connectors
for each panel. The top connector is for Adapter Board A, and the bottom
connector is for Adapter Board B.
Note: Ribbon Cable is not included with all E31 models. For ribbon cable
options, see Recommended Accessories on page 11.
2. Auxiliary Inputs: These 0.333VAC inputs are used for monitoring the main
breaker or other high amperage source. Inputs on the left are for panelboard 1;
inputs on the right are for panelboard 2.
3. Control (Mains) Power Connection: Easy 2-wire 90-277 VAC 50/60 Hz
connection.
4. Control Power Fuse: 600VAC, 500mA time lag, factory-replaceable.
5. Alive LED: Red/green/amber LEDs. Blink codes are on page 3.
6. Voltage Taps: 1, 2, or 3 phase plus neutral connections. For voltage sensing and
power calculations (no voltage taps on the E31C). Voltage taps are shared by both
panels.
7. Communications Address DIP Switch: Each Modbus device must have a unique
address. Switches are binary weighted. Left-most switch has a value of 1; right-
most switch has a value of 128. Note: switches set the address for panel 1; panel 2
is automatically set to (Panel 1 address + 1). See Configuration section for details.
8. Communications Settings DIP Switch: Configures baud rate, parity, 2- or
4-wire communications.
9. RS-485 Connection: Used for Modbus serial communications. The Universal plug
accomodates 2 or 4 wire connections.
10. RS-485 LEDs: The RX LED (closest to DIP switches) indicates the RS-485 is
receiving information; the TX LED indicates transmission of information.
11. Power LED: Indicates power to main board
12. Branch Current Sensors: Each split-core current sensor is capable of monitoring
conductors rated up to a maximum of 50, 100, or 200 amps. Up to 84 sensors can
be purchased with the E31 (see Recommended Accessories on page 10). One of
each style is pictured here.
