Note: An indep12-24 Vdc

using an RST-6001 Modbus Controller.

The RST-6001 can only supply ±5 Vdc,

not the +12-24 Vdc required by the MPX.

IMPORTANT

: For surge protection on MPX-E4 or -R4, either connect the grounding 

screw (see pages 1-3) to an earth ground, or ensure that the tank mounting of the MPX is 
grounded.
