TS-8900 Functional Test System Site Preparation and Installation Guide
• Conventional 50/60-hertz current probes cannot make
accurate input current measurements of the system's power
supplies due to the harmonics on the currents. A current
measuring instrument needs a bandwidth that is above 10
kHz. Improper instruments may yield results that are 50
percent less than actual.
• For the E1135C, system input power connections on the PDU
are made to an input connector block and the ground
connection to a terminal bolted to the chassis. Power is
connected to the mains disconnect switch and a ground
terminal attached to the chassis. For ease of installation, in
areas where it meets local code requirements, use
multi-strand wire from a AC mains to the PDU.
For the E1135C, ten thermally-activated circuit breakers designer to
protect the output terminal blocked are located on the front of the
PDU. Under normal operation, a detected fault sets the rocker on
the breaker to the open position. Reset the rocker by gently pushing
it back in place. These breaker must not be opened by force or
permanent damage can result. Damaged caused by intentionally
opening the breaker is not covered by warranty.
