Chapter 2 Install the Armor PowerFlex Drive
Power Supply Requirements
You can apply the Armor PowerFlex drive with an external 24V DC auxiliary
power supply. The external auxiliary power supply will power up
communication, inputs, and outputs. The external power supply provides
unswitched and switched 24V DC to the Armor PowerFlex drive.
These are the requirements for an external auxiliary power supply:
•
Rated for 24V DC nominal (tolerance 18…32V DC)
•
The supply should be PELV or SELV type
•
The supply must be capable of 150% current boost power for at least one
second
As an option, you can select an internal power supply (IPS). With this option
selected, you do not require an external power supply. The Armor PowerFlex
drive will internally source the 24V DC power for communications, inputs, and
outputs.
The 24V DC IPS is sourced from the three-phase power coming into the Armor
PowerFlex drive. The IPS circuitry connects to the line side of the local
disconnect, which means that when the local disconnect on the Armor
PowerFlex drive is in the Off position, the IPS will continue to provide 24V DC
power. To shutdown the IPS output power, the main disconnect must be set to
the Off position, to remove all three-phase power coming into the Armor
PowerFlex drive.
You can install, configure, and operate the I/O without three-phase power
connected, if you order an Armor PowerFlex drive with the external power
supply configuration and if you provide external unswitched 24V DC to the
product.
IMPORTANT
There is an instantaneous inrush of 6.5 A for 15 milliseconds. The
external 24V DC power supply must be able to support this
demand when multiple Armor PowerFlex drives are turned ON
simultaneously. For supplies without this capacity, we
recommend applying unswitched power first and after a 2…4
second delay, apply switched power. If auxiliary power falls
below 19V DC, there is a higher risk of communications issues or
device faults.
IMPORTANT
Both a switched and unswitched 24V supply from this source are
provided to the safety subsystem. The installer is responsible for
providing safety power that is PELV or SELV rated.
IMPORTANT
To comply with the CE Low Voltage Directive (LVD), all
connections to this equipment must be powered from a source
compliant with the following:
• Safety extra low voltage (SELV) Supply
• Protected extra low voltage (PELV) Supply
To comply with UL/cUL requirements, this equipment must be
powered from a source compliant with the following:
• IEC 60950-1 Ed. 2.1, Clause 2.2 - SELV Circuits
