Connect the remote-start pendant
Configurations of a Powermax45 with a T45m also can include a 7.62 m / 25-foot (128650), 15.24 m / 50-foot
(128651), or 22.86 m / 75-foot (128652) remote-start pendant. To use the Hypertherm remote-start pendant, plug it
into the receptacle on the rear of the power supply.
Note: The remote-start pendant is for use only with a machine torch. It will not operate if a hand torch is installed.
Connect a machine interface cable
The Powermax45 is equipped with a factory-installed voltage divider that is designed to be safely connected without
tools. The built-in voltage divider provides a 50:1 arc voltage. A receptacle on the rear of the power supply provides
access to the 50:1 arc voltage and signals for arc transfer and plasma start.
CAUTIoN
The factory-installed internal voltage divider provides a maximum of 7 V under open circuit
conditions. This is an impedance-protected functional extra low voltage (elV) output to prevent
shock, energy, and fire under normal conditions at the machine interface receptacle and under single
fault conditions with the machine interface wiring. The voltage divider is not fault tolerant and elV
outputs do not comply with safety extra low voltage (SelV) requirements for direct connection to
computer products.
Hypertherm offers several choices of machine interface cables for the Powermax45:
• To use the built-in voltage divider that provides a 50:1 arc voltage in addition to signals for arc transfer and
plasma start:
— Use kit number 228350 (7.62 m, 25 feet) or 228351 (15.24 m, 50 feet) for 6 wires terminated with spade
connectors. (The following diagram shows an example of spade connectors.)
— Use part number 223048 (7.62 m, 25 feet) or 123896 (15.24 m, 50 feet) for a cable terminated with a
D-sub connector. (Compatible with Hypertherm’s EDGE ® Pro Ti and Sensor™ PHC products.)
