Cee-Form U.S. Operation
Cee-Form 120VAC Operation
Switch Position “Input Pin/Sleeve, Output US/120 EU/240” provides 120VAC
operation from the Cee-Form pin and sleeve connector. From an external
power distribution system, send 3 phase 120VAC power to the X, Y, and Z pin
of the Cee-Form connector and the VRack will operate in 120VAC operation
mode. Each I-Tech HD amplifier will see a dedicated line-to-neutral connection
as well as a ground. Once the Cee-Form connector is landed to the VRack,
one can link to the next VRack using a Cee-Form jumper cable. (***To link
VRacks using this method at 110VAC-120VAC, the end user must ensure they
have proper AC current available. Also, please refer to the I-Tech HD Thermal
and Current Draw specifications to ensure you are not overloading the AC lines,
resulting in breakers opening. It is recommended if you wish to link VRacks,
they be operated at 220VAC-240VAC.)
Amp 1 = X, Neutral, and GND
Amp 2 = Y, Neutral, and GND
Amp 3 = Z, Neutral, and GND
Cee-Form 208VAC Operation
Switch Position “Input Pin/Sleeve, Output US/208” provides 208VAC Operation
from the Cee-Form pin and sleeve connector. From an external power
distribution system, send 3 phase 120VAC power to the X, Y, and Z pin of the
Cee-Form connector and the VRack will operate in 208VAC operation mode.
Each I-Tech HD amplifier will see a dedicated line-to-line connection as well
as ground. In “Input Pin/Sleeve, Output US/208” mode, the end user is able
to link 2 VRacks together. Amp 1 = X, Y, and GND
Amp 2 = Y, Z, and GND
Amp 3 = X, Z, and GND
Cee-Form Non-U.S. Operation
Cee-Form 220VAC-240VAC Operation
Switch Position “Input Pin/Sleeve, Output US/120 EU/240” provides 220VAC-
240VAC operation from the Cee-Form pin and sleeve connector. From an
external power distribution system, send 3 phase 220VAC-240VAC power
to the X, Y, and Z pin of the Cee-Form connector and the VRack will operate
in 220VAC-240VAC operation mode. Each I-Tech HD amplifier will see a
dedicated line-to-neutral connection as well as a ground. Once the Cee-Form
connector is landed to the VRack, one can link to the next VRack using a Cee-
Form jumper cable. (***To link VRacks using this method at 220VAC-240VAC,
the end user must ensure they have proper AC current available. Also, please
refer to the I-Tech HD Thermal and Current Draw specifications to ensure you are
not overloading the AC lines, resulting in breakers opening. It is recommended
