Position the power supply
Locate the Powermax45 near an appropriate 200–240 volt power receptacle for CSA or CE 1-phase power supplies,
a 400 volt receptacle for 3-phase CE power supplies, or a 480 volt receptacle for 3-phase CSA power supplies. The
Powermax45 has a 3 m (10-foot) power cord. Allow at least 0.25 m (10 inches) of space around the power supply for
proper ventilation.
Prepare the electrical power
The maximum output voltage will vary based on your input voltage and the circuit’s amperage. Because the current
draw varies during startup, slow-blow fuses are recommended as shown in the following chart. Slow-blow fuses can
withstand currents up to 10 times the rated value for short periods of time.
Voltage configurations
The following chart shows the maximum rated output for typical combinations of input voltage and amperage.
Acceptable input voltages can be ±10% of the values given below.
CAUTIoN
Protect the circuit with appropriately sized time-delay (slow-blow) fuses and a line-disconnect
switch.
