Operation Manual

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
