Three Phase Output - Pacific Power Source ASX series Operation Manual

SECTION 3 INSTALLATION

3.4.3 THREE PHASE OUTPUT

WARNING
LETHAL VOLTAGES ARE PRESENT AT THE OUTPUT TERMINALS OF THIS MACHINE!
REFER OUTPUT CONNECTION TO A QUALIFIED ELECTRICIAN.
.
To operate an ASX-Series power source with three phase output, set the controller for FORM3.
Figures 3.4.3.1 and 3.4.3.2 show a three phase load connected to the output of an ASX-Series 3φ
Power Source
The output power is taken from the terminal block located on the rear panel of the chassis labeled
"OUTPUT POWER". This Output Form is set for 3 PHASE when these types of load are
connected.
This power form has a direct-coupled voltage range of 0-132 VAC (Models 315-ASX and
l-n
360-ASX),0-135 VAC (Models 345-ASX and 3120-ASX), or 0-150 VAC (Model 320-ASX).

WYE loads are connected to "φA," "φB," "φC," and "N" terminals as shown in Figures 3.4.3.1 and
3.4.3.2. In the case of DELTA loads, the "N" terminal is not used.
The "CHS" terminal must always be connected to the chassis of the load. Since the output is
isolated, any output terminal (direct-coupled output only) may be connected to chassis. This allows
the user to re-establish a local ground for the output. The output (preferably Neutral) must be refer-
enced to chassis somewhere. Unless demanded by a particular application, Pacific Power Source
recommends that a jumper be installed across the "N" and "CHS" terminals of the Output Terminal
block.
The "N" terminal of the Output Power Terminal Block must always be connected to the "CHS"
terminal when using transformer-coupled outputs. Refer to Paragraph 3.4.4 for special consider-
ations when using transformer-coupled output forms.
Refer to Paragraph 3.8 for connection of the External Sense Input, when used.
NOTE: It is the user's responsibility to meet all local and national electrical codes when
installing this equipment.
