OUTPUT POWER CONNECTION

The ACX provides output connections at both the front and rear of the chassis. Front panel load
connection is through a universal outlet socket. Available current at this socket is 10 amps max., protected
by a circuit breaker located at the rear of the unit. Rear panel load connection is available through a
terminal block which is rated for the full output current of the ACX. Figure 3.3 illustrates connection of a
single-phase load to the ACX rear-panel terminal. Refer to Paragraph 2.1.2 for minimum output service
requirements for various output voltages and size the output wires accordingly.

NOTE:
For safe operation, the PE ground terminal should always be connected to the chassis of the load.
Output power should also be referenced to the chassis, unless otherwise demanded. The output
is isolated but insulation specifications require that no more than 150 Vac be present between the
output neutral (LINE2 or N) and chassis. For single-phase applications, a jumper should be
attached between LINE2 and PE/GND. For applications using the high range as a split-phase
configuration, the jumper should be attached between N and PE/GND.
Refer to Paragraph 3.7 for connection of the External Sense connection, when used.
The ACX Power Source output can be configured for single and split phase voltage forms. Figure
3.4 is a simplified block diagram of the possible output architectures.
The FORM1 (low range, 0-150 Vac) mode of operation is a one vector output form, single-phase
only. The power amplifiers are connected in parallel to form one output vector. The load can be
attached from LINE1 to LINE2 or LINE1 to N. In this form, LINE2 and Neutral are connected. This
output form is capable of 0-150 VAC
The FORM2 (high range, 0-300 Vac) mode of operation is a two vector output form where the
vectors are separated by 180° and equal in amplitude. This output form uses power amplifiers in
pairs, one for each vector.
For single phase 0-300 VAC
For loads that require three connections (L
LINE 1 and LINE 2 are equal in voltage and 180 degrees apart, referenced to Neutral. Loads can
be connected from either LINE to Neutral or from LINE1 to LINE2.
WARNING
ATTENTION
CONNECTION DES BORNES DE SORTIE
No metal parts should be touching the output terminals as dangerous
voltage may be present. It is the user's responsibility to meet all local and
national electrical codes when installing this equipment.
