Step 2 - Check the type of ac supply
Check the type of ac supply required (see Specifications on page
).
Only use an ac supply referenced to ground, or with a protection system so that the
phase-ground voltage cannot exceed the rating of the rectifier.
Step 3 - Disconnect device and overcurrent protection (some models only)
Ignore this step if the APS has an integral ac supplementary protector. See Model
Numbers on page
.
Confirm that the following requirements are complied with:
1
For permanently connected models without an integral ac supplementary
protector:
•
A readily accessible disconnect device shall be incorporated external to the
APS.
•
The disconnect device shall be a circuit breaker suitable for Branch Circuits
and rated 40A or less.
2
For models with IEC plug and cord sets:
•
The plug is a suitable disconnect device if the socket is installed near to the
APS and is readily accessible.
•
Otherwise, each cord must be supplied via a readily accessible circuit
breaker suitable for Branch Circuits and rated 15A.
3
In all cases, the external circuit breaker(s) must be two-pole type wired in each
conductor, if:
•
the ac supply is 2W (see Specifications on page
), or
•
the ac supply is 1W+N but the neutral is not clearly identified.
