Bypass Static Switch Wiring

WARNING!

Use only manual reset protection as input over-current protection.

WARNING!

Over-current protection required by code.

WARNING!

The UPS has no internal manual disconnect devices to switch off external AC (Q1 and Q5) and DC (Q7 and Q8) input power. Ensure that disconnection devices are available as separate components for this installation.

CAUTION!

The External Bypass Static Switch is not provided with built-in backfeed protection. The breaker is controlled from the External Bypass SSW and will be tripped in case of backfeed.

The installer must provide each external disconnection device for this UPS system with labels displaying the following text:

“Isolate the Uninterruptible Power Supply (UPS) as instructed in the User Guide before Note working on circuit.”

The installation of the External Bypass Static Switch must comply with local and national codes.

Note

Run matched set of phase cables in the same cable run(s).

Do not separate phases into different cable runs.

Note

For information on cable lugs, cable ratings, over-current protection and the disconnection switches, refer to “Specifications” .
