SPECIFICATIONS
Enclosure
NEMA 4X / IP65.
To prevent any interference from electromagnetic radiation, use
rigid metal conduit to enclose the wiring entering the ER3000. Two
1/2" NPT wire ports have been provided for this purpose. If unused,
properly seal with a metal plug.
Media
The preferred media is clean, dry instrument grade air or nitrogen.
Use of an in-line 40-micron filter is highly recommended to prevent
damage to the solenoid valves.
