Installation Step 5: Electrical Power
AC Source Requirements: Operating Voltage: 230 VAC ± 10% (under load) @ 50/60Hz; 15 Amps
maximum, single phase.
The Vertex Edge system requires a dedicated AC source rated at 230 VAC @ 50/60Hz, 15 Amp
single phase providing hot, neutral, and ground lines. Line voltage should fluctuate no more
than ± 10%. The external switch must be clearly labeled and installed in accordance with local
electrical codes. Input power cable should be #14 AWG minimum. The safety ground wire must
be the same or larger gauge as the line wires. Connect AC power connection to the two-position
terminal block in the rear panel of the power module. Connect ground wire to the threaded stud
on the side rail of the rack.
NOTE
Testing has shown that using 208/220VAC phase-to-phase power source instead of the
recommended 230VAC phase-to-neutral, can result in voltage excursions on the system
ground. The excursions can cause damage to components in the analyzers. This type of
damage is most likely to occur during system power cycles or in cases where the supply
power is not a clean source. For applications where 230 VAC single phase power is not
available, Honeywell Analytics offers transformers to provide the necessary power.
NOTE
It is important to verify that all 5 of the AC connections to the PDU are fully connected. This
needs to be done before power up. Refer to See "System Components" on page 11 for more
information. to identify these 5 AC connections.
