Checking the Electronic Module Connections
WARNING
All connections to electronic module in the SVI II ESD are made through the terminal board. There
are three versions of the terminal board, dependent on the configuration you have; ASD, DSD, or
A/DSD. The SVI II ESD terminal board has a terminal block with cage clamp connectors. Confirm
that all applicable connections to the electronics module connectors are correct. Not all options
are available for every model. Refer to Table 5 for available functionality.
