How to Set Address DIP Switches
Each DIP switch has a numerical value as shown below. The EA10 default address is 1,
as illustrated below.
On
Off
1 2 3 4 5 6 7 8
1 2 4 8 16 32 64 128
(DIP Switch Values)
To determine an address, add the values of any switch that is in the ON position.
For example:
1 2 3 4 5 6 7 8
On
Off
1 2 4 8 16 32 64 128
(DIP Switch Values)
Switches 4 and 6 are in the ON position, with values of 8 and 32, respectively.
8 + 32 = 40, so the EA10 address is 40.

Reverse Current Switch
The reverse current switch allows the user to define the polarity of the instantaneous
current reported by the unit. In the default Off position, the unit reports positive
current when the conductor is routed through the CT with current flowing towards
the DC current sensing module LEDs (see drawing below). Negative current flows
away from LEDs towards the CT, indicating a diagnostic event. When the reverse
current switch is On, the opposite is true (see drawing below). This feature allows the
product to be installed in a variety of configurations.
The state of the reverse current switch can be overridden by writing to the
configuration register via Modbus (see EA10 Modbus Point Map, System Configuration
Register 40357). To reactivate the switch, clear the Modbus register.
