Connector and wiring details

All VARI input and output connectors are located in the connector compartment at the bottom
of the VARI‑B or VARI‑BH base unit. The IEC AC mains socket is immediately adjacent.
Except for the mains connection, all other connections to the VARI base unit are made via
Phoenix-type screw‑terminal connectors. All mating connectors are supplied; note that three
different sizes are used. All connectors on the VARI have male contacts.
The pinouts of each connector are given in the next paragraphs.
