Wiring
The PAX1 can be controlled with three different control
interfaces (Analog, Pulse & Modbus). The wiring diagrams,
Figures 3-8, below show the connections required to operate
the unit based on the control type as well as connections to
other features such as position feedback and alarm switches.
The terminal blocks can accommodate wire size up to 1.5 mm
(14 ga.). Due to safety requirements, wire entering TB2 and
TB3 terminal blocks (alarm relays) require ferrules (supplied)
to provide proper insulation for high voltage AC connections.
The AC powered PAX units also require crimp ferrules for
wires entering the terminal block at connection 11 & 12.
Crimp ferrule onto wire, then
clamp it in the terminal block.

Grounding
An internal ground lug is provided. Use the ring terminal
provided to make an internal ground connection to the unit
using 14 to 18 ga. wire.
