OUTPUT POWER CONNECTION

The connection of the load to the output of the AMX-Series Power Source is described in this
section.

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 FORM 1 when this type of load is
attached.
The high side of the load is connected to the "1φ" terminal (the "L1" terminal on the Model
125-AMX) when making connections to an AMX-Series Power Source.
terminal on the Model 125-AMX) terminal is the low side of the output. The low side of the
load connects to this terminal in all models.
The "CHS" 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 refer-
enced to chassis somewhere, preferably neutral. Unless demanded otherwise by a par-
ticular application, Pacific Power Source recommends that a jumper be installed across the
"N" ("L2" for Model 125-AMX) 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.
