Product Overview

EP-8000 Series Electro-Pneumatic Transducers Product/Technical Bulletin 5
Observe the following guidelines when making wiring
connections:
• Remove the cover of the EP-8000 by gently
prying up on the two snap-in cover tabs.
• Observe the polarity as designated on the
terminal block of the EP-8000.
• Provides adequate stress relief for the wiring.
A wiring entry slot is molded into the cover for
routing to an analog DC source.
Observe the following guidelines when making
pneumatic connections:
• Use 5/32 or 1/4 in. polytubing.
• Use clean, dry, oil-free air.
IMPORTANT: To avoid contamination of the
unit, install an inline supply filter.
Note: For low-volume models, this inline filter must
be installed in the supply air line before the
0.007 inch restrictor (see Figure 10).
