5.1 The above GTU’s are intially tested at the PC Board testing department as a
480VAC, 3
∅
, 50/60Hz, Standard one second ramp, RMS Voltage Regulator.
5.1.1 Refer to the proper schematic and assembly drawings
5.2 Customer Specifications
5.2.1
The GTU configuration is selected by the Customer Service order options program.
Line Voltage is selected by Customer Specifications
The line voltage is selected by a wire connection on each of 3 transformers. The wire
must be moved to the appropriate voltage tap and soldered.
Seven jumpers are used to configure the GTU to Customer Specifications. All Jumpers are
received in the “A” position from the PWBA Vendor.
