7.2.2
Load Connection without External Voltage Sense
AFX Series® power sources can be operated with internal voltage sense. For higher current
loads, the voltage at the load will drop due to the load cable impedance. Using the proper
wire gauge for the rated current of the AC source is required to minimize load cable
impedance.
7.2.3
Load Connection with External Voltage Sense.
The following points must be considered, when existing sense cables are connected directly
to the load or to the central load distribution point:
1.
Minimize the distance between the AC power source and the load as much as
possible to keep load wire length to a minimum.
2.
Directly connect
A, B, C
and
N
with
correct phasing
to the load distribution point
3.
Twist each phase sense wire with a neutral sense wire to minimize cross talk. Three
neutral connection points are provided for this purpose.
4.
Avoid overload of power wires
Note:
External voltage sense connections are at the programmed output voltage when the
output is on so DO NOT connect or disconnect the external voltage sense lines while the AC
power source is in use.
Units are shipped with the mating sense connector installed but no wires to prevent contact
with the sense connections.
