4.6 Inspection and Maintenance

The following inspections are recommended two times per year for best long-term performance.

System Inspection

• Conﬁ rm the controller is securely mounted in a clean and dry environment.

• Conﬁ rm that the air ﬂ ow around the controller is not blocked. Clean the heat sink of any

dirt or debris.

• Inspect all exposed conductors for insulation damage due to sun damage, rubbing on

nearby objects, dry rot, insects, or rodents. Repair or replace conductors as necessary.

• Tighten all power connections per the manufacturer’s recommendations.

• Verify the LED indications are consistent with the equipment operation. Note any fault or

error indications. Take corrective action if necessary.

• Inspect the battery bank. Look for cracked or bulging cases and corroded terminals.

For wet cell ﬂ ooded batteries, make sure the water level is correct. Wet cell water levels

should also be checked frequently according to the manufacturer’s recommendations.

• Inspect the system earth grounding for all components. Verify all grounding conductors

are appropriately secured to earth ground.
