*Installation Notes
- Installation must be performed only by electrically skilled operator.
- Disconnect power before installing, no hot-line operation is allowed, and better to under the guidance of professional electrician.
- For best performance, mount protector in parallel with the equipment it is protecting as close as possible. (*Note: If protector is to be located outdoors and exposed to elements, mount protector inside a suitable weatherproof enclosure.)
- Use a circuit breaker in series with the protector.(*Note: if a breaker is not available, use a fused disconnect switch or a fuse block. Fuses should be time-delay type.)
- Green tab, normal work status, Red tab, failure status, need to be replaced rapidly.
