Electrical Considerations
1.
Insure all conduit openings are sealed properly following the installation of all required field
wiring, thereby, prohibiting water from entering the enclosure. Alterations to the enclosure void both the
UL Listing and the product Warranty.
2.
Insure the desired I/O modules are installed prior to operation. All I/O modules may be solid
state AC or DC modules. Some output modules may be mechanical.
3.
If PAC-3 injectors are being upgraded to the ProPAC-3 model, the existing wiring may have to
be replaced if it is too short. The existing PAC-3 Hall effect sensor should be replaced with the short
version of the sensor designed for the ProPAC-3.
4.
Insure all DC I/O and communications wiring is installed in a separate conduit from any AC
wiring. AC wiring should be run in dedicated conduit for AC.
5.
All DC I/O and serial communications wiring should be shielded Belden cable, in order to
protect the signal integrity.
6.
The ProPAC-3 utilizes solid-state relays for all inputs. Because of the potential for current
leakage when using a solid-state device, never provide inputs to the ProPAC-3, which originate from a
solid-state device unless a resistor is installed to "bleed down" the current leakage.
7.
The ProPAC-3 main circuit board utilizes Wago connectors for all AC, DC and serial
communications connections. Wago connectors are a very high quality connector providing a positive lock
on the wiring. A special Wago tool is provided in connector P4 (Power) and is useful for terminating all
electrical connections. The Wago tool is used as a lever to open the connection for wiring. Insure the wire is
engaged properly and not the wiring insulation.
Note:
If the Wago tool is not installed, a miniature flat head screwdriver (-0.125"/ 3mm) may be used to
open the connector for wiring. See below.
