Electrical Connections
The HM-2800 arrives ready for operation. Attach the supplied IEC
electrical cord to the machine and plug into a standard wall receptacle
for use in the United States.
The 220 50/60Hz variation of the HM-2800, the HM-2800.4F includes a
step-down transformer, which allows the HM-2800 to be used with 220
50/60Hz applications. The step-down transformer is a external device,
which comes pre-wired with a supplied cable but no plug. The cable
can be used to hard-wire the transformer to your 220 50/60Hz source,
or you can install an appropriate plug. The transformer can then be
plugged into the HM-2800 with the supplied cable.
