Electrical Noise Guidelines
PECC has taken the following measures to reduce electrical noise with
the HFG2.0:
the HFG2.0:
• High-voltage wires are routed separately from low-level signals
through the use of separate power and signal harnesses.
An additional measure to reduce electrical noise is to:
• Ensure that the HFG2.0 is properly grounded, as per Section 1.4
of this manual.
Environmental Considerations
The HFG2.0 operates satisfactorily with ambient air temperature of -40
°C
(-40
°F) to +93 °C (+200 °F), and is designed as an explosion-proof
assembly. The HFG2.0 enclosure is Canadian Standards Association
(CSA) Type 3, European IP65.
