Manual Energy Storage Inverter ESI-S
Electrical design and installation 65
Two connection approaches exist:
−
The first approach is to use one digital input for the start function and the second
digital input for the stop function.

input considered and the resulting effect when applying voltage to this input.

digital input
Vlow applied to digital
input
Vhigh applied to digital input
Edge ON
No effect
Inverter starts on rising edge
Edge OFF
No effect
Inverter stops on rising edge
Remark: Vlow = 0 Vdc, Vhigh = 15-24 Vdc
When using the Edge ON function the inverter can only be switched on by applying
voltage to the digital input considered. It is therefore recommended in that case to
configure and cable the second digital input as Edge OFF. Refer to
Section 7.9.2.4.2
guidelines on how to set up the digital inputs according to the function required.
The electrical requirements of the digital inputs are as discussed in

and a stop function on the second digital input.

The second approach is to use one digital input for both the start function and
the stop function. This leaves the other digital input available for the
implementation of other functions.
