Set Up and Operation
? Two different gain settings for the inverter leg shunt and DC bus shunt feedback
are implemented via LK5-12. These are located directly under the “Danger High
Voltage” label on the PCB as shown in Section 9. The user should consult the
schematics in Appendix A, Sheet 3 to establish which links correspond to which
signal. Note that links must be changed in pairs (e.g., LK5 and LK6 together or
LK7 and LK8 together, etc.) for correct operation. See below.
? The scaling and trip levels for the inverter leg shunt signals are shown in the

Note: The shaded setting should not be used, as it will not adequately protect the
power devices from thermal overload.

? Changing the Hall sensors scaling is accomplished via solderable links (e.g., LK1,
LK2 and LK3 for U1). These are located adjacent to the transducers. The links
change the number of turns that pass through the transducer over a 3:1 range.
Tinned copper wire of a suitable current rating should be used. Only one link at a
time should be used or unpredictable current scaling will occur. The user
should ensure that the maximum length of lead protruding below the PCB is 4 mm
for voltage clearance reasons. The scaling and corresponding trip levels for U2
