Frequently Asked Questions

Q: What power supply range does the 339-E-P1-G1-H-E-S-N-P-3E-D-N relay require for operation?

A: The unit operates on a high-voltage auxiliary power supply ranging from 110-250 VDC or 110-230 VAC.

Q: Does this specific model configuration include a harsh environment conformal coating?

A: No, this variant utilizes a standard drawout case design without the optional conformal coating, maintaining an IP40 rating on the front panel and IP10 on the rear.

Field Installation Guidelines

Ensure that auxiliary control power and main motor circuit breakers are completely de-energized and locked out prior to mounting or wiring the 339-E-P1-G1-H-E-S-N-P-3E-D-N relay. Connect current transformer (CT) secondary leads securely to the 1A terminals, ensuring proper grounding to prevent dangerous open-circuit high voltages. Route all communication and control wiring through dedicated metal conduits, keeping signal cables separated from high-voltage power lines to minimize electromagnetic interference.
