4.4.1 Power Supply (Plug 3)
The ELV-PRO requires a regulated 24VDC power supply. There are two input supply connections for
both the 0V and +24VDC inputs. These connections are internally connected. Terminals P3_1 & P3_2
are the positive supply inputs. Terminals P3_3 & P3_4 are the negative supply inputs.

– ELV-PRO Power Supply (Plug 3)
NOTE
There are two internally connected input supply terminations for each
input. The additional connection is to allow for daisy chaining to other
devices.
4.4.2 Trip Reset and Digital Inputs (Plug 2 & Plug 4)
The trip reset and digital inputs are split across two plugs; Plug 2 and Plug 4 (see Figure 4-5). Plug 2
(right) is a dedicated digital input and Trip Reset 24V supply. All terminals of plug 2 are internally
connected. Plug 4 (left) is a dedicated input plug; terminals P4_1 - P4_5 are assignable digital inputs,
with terminal P4_6 the Reset input. The Trip Reset Input allows the ELV-PRO to be reset remotely.
