17.2.5 IRT Wiring for 6-Star Delta Starter
Figure 136 below illustrates the wiring when the Insulation Resistance Test (IRT) is used with a 6 wire Star-
Delta Starter. The MultiSmart IRT outputs are connected to one phase of each pump as shown.

17.3 Reassigning (Motor) Current Inputs used in Motor Protection
If an Energy Monitoring and Motor Protection (3MP) board is installed and is selected during the Setup
Wizard (as being in the bottom slot), then the motor Current Inputs (for each phase) for three motors are
automatically assigned.
The following procedure only applies if it becomes necessary to modify the default motor Current Inputs. As
an example, navigate to:
• Select Amps A
• Press the "Use this button to view or change value." button to reveal the node list.
(The highlighted node that appears in this screen is the currently assigned Current Input.)
• Scroll down to:- … IIN / _2 / Amps A , and press Ok
• Repeat for the other 2 phases and then press Save
This has reassigned Current Inputs "2" (i.e. current inputs 2A, 2B and 2C) to pump 1 (rather than pump 2).
Repeat this procedure for each pump that requires the default motor Input Currents to be modified from the
default.
