Figure 2.2 PCU2 and loading unit connections
WARNING
It is vital to ensure that secure, low impedance connections are made between the output of
the loading unit and the object under test. Ensure that the output cables are suitable rated for
the test current to avoid danger of fire. If the connection to the load is broken whilst current is
flowing, arcing may occur.
CAUTION
The output terminals and test leads may become hot during use. Allow adequate time to
cool after the test before touching.
2.3.1 Earthing
If the supply earth to the PCU2 is of doubtful integrity the earth terminal on the PCU2 should
be connected to a solid local earth.
