3.2.3 Earth Leakage Toroid
The IPM requires a summation toroid to be installed around the outlet‟s
three phase conductors. This toroid allows the IPM to measure the
magnitude of outlet‟s earth leakage current. Only one (1) earth leakage
toroid is required per IPM. The IPM‟s earth leakage toroids are 1000:1 and
have an 88mm inner diameter.
3.2.4 Remote Termination
Module (RTM) (Optional)
The RTM is an optional component in the IPM system. It is
used to terminate the pilot cable in the motor enclosure
instead of a diode. When used, the RTM stores the IPM‟s
Group 2 protection settings for that particular motor. This
means that the cable supplying the motor can be moved to
another outlet without the need to re-configure all of the
IPM‟s protection settings. The RTM also offers a remote
start input.
