Please refer to the Appendices for details of each build variant.
The ITAs are a standard size (170mm x 110mm) enabling a set area
in the back of each panel to be allocated for ITA placement. ITAs can
be grouped in order of voltage, ITA type, field zone, etc.
The ITAs are packaged in a DIN Rail mounting PCB Carrier to provide
rapid assembly.
The Varelco versions of the ITAs have space allowance for a 90-Way
hood to be used on the mounting half of the field marshaling cable.
