Installation & Maintenance Protocol

Ensure optimal performance in switchgear applications:

1. Verify switchgear compartment dimensions ≥600×400×650mm

2. Use Class H insulation-rated connections

3. Perform annual power factor tip-up tests

4. Monitor partial discharge levels semi-annually

5. Check torque values on power terminals (50N·m ±5%)

6. Validate attenuation performance every 24 months
