OUTPUT POWER CONNECTION
This paragraph describes connection of the load to the ASX-Series Power Source.
3.4.1 SINGLE PHASE OUTPUT
To operate an ASX-Series power source with single phase output, set the controller for FORM1.
Figures 3.4.1.1 and 3.4.1.2 show a single phase load connected to the output of an ASX-Series
Power Source.
The output power is taken from the terminal block located on the rear panel of the chassis labeled
"OUTPUT POWER". The Output Form is set for 1 PHASE when this type of load is attached.
This power form has a direct-coupled voltage range of 0-132 VAC
l-n
(Models 115-ASX, 160-ASX,
315-ASX, & 360-ASX), 0-135 VAC
l-n
(Models 140-ASX, 345-ASX, & 3120-ASX), or 0-150 VAC
l-n
(Models 120-ASX and 320-ASX). The high side of the load is connected to the "1
φ
" terminal and
the low side of the load to the "N" terminal.
For safe operation, the "CHS" terminal should always be connected to the chassis of the load.
Since the output is isolated, either 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) should be referenced 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.
WARNING
LETHAL VOLTAGES ARE PRESENT AT THE OUTPUT TERMINALS OF THIS MACHINE !
REFER OUTPUT CONNECTION TO A QUALIFIED ELECTRICIAN.
