Installation considerations
1. Prior to installation, confirm complete power isolation. Any operation under live conditions is expressly forbidden.
2. The surge protector's input side should incorporate an in-line fuse or circuit breaker as protective measure.
3. Adhere strictly to the provided wiring schematic: DC+ denotes positive terminal, DC- indicates negative terminal, and PE represents grounding conductor. Ensure proper polarity during installation. Upon completion, activate the protective device (circuit breaker/fuse) and validate normal operational parameters.
4. Following installation, properly position the unit and conduct functional verification of the surge protective device.
5. Implement periodic maintenance checks on the surge protector, including monitoring of the diagnostic indicator. A red warning display or alarm contact activation signifies device failure requiring immediate attention through repair or replacement.
6. When installing multiple surge protectors in parallel configuration, maintain true parallel wiring with properly secured connections using appropriately sized conductors of minimal length and direct routing.
