Operating Instructions
The LTC Low Terminal Covers are passive components designed to provide protection for electrical terminals. They do not have active operational functions. Once installed, their purpose is to insulate and protect the low terminals of the automatic switch from accidental contact and environmental factors.
- Ensure covers remain securely in place during operation of the automatic switch.
- Do not attempt to remove covers while the switch is energized.
Maintenance
These terminal covers require minimal maintenance. Regular inspection is recommended to ensure their integrity and proper function.
- Cleaning: If necessary, clean the covers with a dry, lint-free cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically check for any signs of damage, cracks, or discoloration. Ensure they remain securely attached to the automatic switch.
- Replacement: If a cover is damaged or no longer fits securely, replace it immediately with an authentic ABB replacement part (Model: 1SDA107476R1).
