Frequently Asked Questions (FAQ)

Q1: Is this cover compatible with Experion PKS Series C modules?
A1: No. It is designed for LCN hardware in TDC 3000 and TPS systems only.

Q2: Can the node operate without the cover?
A2: Physically yes, but not recommended. The cover is critical for airflow and EMI protection; running without it can shorten electronics lifespan.

Q3: Are mounting screws or clips included?
A3: Usually sold standalone. Snap into the existing frame or reuse previous screws. Ensure ground contact points are clean.

Q4: What if the cover doesn't fit securely?
A4: Check that internal boards are seated correctly, no cables obstruct mounting, and the steel frame isn’t bent.
