2-20 TP04300 Series Interface & Applications Manual
AC Power Standards
The TP04300 includes a 32 amp power cord, approximately 3 meters long.
For 60 Hz systems, the power cord is terminated in a standard 230 v plug.
For 50 Hz systems, the power cord is not terminated with a plug: attach a plug appropriate to
the facility and local electrical power code.
As specified at the time of purchase, the TP04300 must be connected to a source of single-
phase ac power which must be capable of supplying the required minimum amperes.
The TP04300 comes with a custom auto-transformer to adjust for other supply voltages and
frequencies.
Power
Requirements
200 - 240 VAC (230V nominal), 50Hz, 30amp, 1 phase
200 - 240 VAC (230V nominal), 60Hz, 30amp, 1 phase
Voltage Configurations
The System is shipped with the voltage configured to the customer’s initial sales order
specification, and is properly wired at the factory.
The system’s auto-transformer is fully integrated into the TP04300 power supply package and
has been factory connected between the main ac power service and the ac power input to the
compressor and heater.
To determine the correct auto-transformer voltage setting:
1. Measure line voltage input to system (see To Measure Input Line Voltage, page 2-21).
2. Connect the auto-transformer wires (see Configuring the Auto-Transformer Wires,
page 2-23).
When configured properly, the Auto-Transformer (T2) will “Boost” or “Buck” the voltage as
needed to achieve an optimal range.
