These drawings show an optional AC line filter, and shielded motor cable. These can be used
in conjunction with the grounded metal enclosure to meet the Electromagnetic Compatibility
requirements of the European Machinery Directive. A discussion of EMC can be found in “Sys-
tem Installation for Electromagnetic Compatibility” on page 2-17.
Auxiliary Logic Power
Single phase AC power, 100–240 VAC, may be supplied to the internal logic supply through L1
AUX and L2/N AUX.
Supply power to the logic supply is useful if the PDM logic must stay ON when the motor
power must be turned OFF. Absolute positioning is one example of when this would be useful,
since position information is maintained as long as logic power is on. Another example would
be maintaining PDM logic power so the PDM serial interface could be used for troubleshooting
and diagnostics.
IQ-5000 PDM
Power Supply Module (PSM)
The Power Supply Module (PSM) can supply DC power to as many as six PDM modules. Three
phase AC power, 115/230 VAC, is the only required input power for the PSM. The input power
may be optionally isolated through a transformer. Field wiring must be copper, with a minimum
rating of 60°C. The phasing of the input power L1, L2, and L3, is arbitrary. The earth ground
connection is required for safe and proper system operation. Terminal block connections should
be torqued to 11 lb-in (1.25 Nm). on the PSM-50 and 24 lb-in (2.75 Nm) on the PSM-125. The IQ-
5000 does not contain supply fuses or disconnecting devices. These must be supplied by the
machine builder and connected externally for safety and maintenance purposes. The Power
Supply Modules will continue to operate with reduced capacity with the loss of one phase. The
red phase loss LED on the front of the PSM will turn ON to indicate the loss of the phase.
Refer to Figure 3.25 on page 3-25 for details. This drawing shows an optional AC line filter, and
shielded motor cable. These can be used in conjunction with the grounded metal enclosure to
meet the Electromagnetic Compatibility requirements of the European Machinery Directive. A
discussion of EMC can be found in “System Installation for Electromagnetic Compatibility” on
page 2-17.

DANGER: Shielded power cables must be grounded at a mini-
mum of one point for safety. Failure to ground a shield power cable
will result in potentially lethal voltages on the shield and anything
connected to it.
!
CAUTION: The power supply module allows for operation to con-
tinue even in the event of loss of one phase or during power
disruption on the three phase AC inputs. Under these conditions,
the Phase Loss LED will light, but the power supply is not disabled.
Extended operation of this product with an AC phase input missing
will reduce the life of the product.
