Site Preparation and Power Requirements
Mains Disconnect Requirements
Although the Agilent PDU (E1135C) contains a mains
disconnect switch, in some cases, the user may also want to
install an external mains disconnect circuit breaker. Be sure the
circuit breaker is adjacent to the equipment for easy access.
Usual mounting is an approved enclosure on a floor-mounted
pedestal.
Disconnect Circuit Breaker Requirements
The disconnect circuit breaker must be:
•
Rated for the maximum system amperes.
•
Approved for use in building installations in your locality,
•
Marked "Mains Disconnect" or the equivalent in your local
language.
•
Marked for the "Off" position.
•
Capable of locking in the "Off" position, but not in the "On"
position.
•
Open all phases and neutral conductors, but not the safety
grounding conductor.
Mains Circuit Breaker Requirements
Requirements for the mains circuit breaker are the same as the
“Disconnect Circuit Breaker Requirements” above plus the
breaker must be rated a minimum 10,000 amperes interrupting
capacity (AIC), for 100-240 V AC circuit, or 14,000 AIC for
higher voltage circuit.
