Single Phase Output - Pacific Power Source LMX Series Operation Manual

5.12.1 Single Phase Output

The wiring requirements for a low range ( 0-135, 0-150 VAC ) single phase load are shown in
Figure 5-8 and Figure 5-9.
The output power is taken from the terminal block located on the rear panel of the chassis
labeled "OUTPUT POWER." The Output configuration is set for FORM 1 (Single Phase) when
this type of load is attached.
The high side of the load is connected to the "1φ" terminal when making connections to an
LMX Series Power Source. The "N" terminal is the low side of the output. The low side of
the load connects to this terminal in all models.
The "CHS" chassis ground terminal must 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 must be referenced to chassis somewhere, preferably neutral. Unless demanded
otherwise 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 Section 5.12.5 for special
considerations when using transformer-coupled output forms. Refer to Section 5.12.4 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.
