For public disclosure
2.1.1.4 Power Requirements
The MFA is powered by a DC Power Supply (9 to 30 V dc, nominal 24 V dc). Power for the MFA shall be provided by a
Class II power supply marked as "double insulated", Limited Power Source (LPS), or a SELV source with a minimum 32 V
dc listed fuse with 3 A max rating. Power for the relay output and discrete input shall be provided by an isolated source.
Reversing input power polarity might cause damage to the MFA.
Caution
The IC690PWR024 (Selectable 115/230V AC input, 24V dc @ 5A Output) DIN Rail mountable power supply meets the
power requirements of the MFA.
The ICMFAACC002 is rated for 100-240 V ac and 47-63 Hz input, and features an IEC-60320 C14 inlet plug for
attachment of the AC power cord. The ICMFAACC002 may be adapted to local power by using a desktop computer-style
AC power cord (with an IEC-60320 C13 connector on one end and the correct AC mains plug on the other).
Caution
The use of the ICMFAACC002 in permanent installations shall be in accordance
with the National Electric Code (NEC), the Canadian Electric Code (CEC), or with
the authority having jurisdiction.
Grounding
There are two ground connections on the Mini Field Agent. One is located on the front power connector and the other is a
chassis screw located on the bottom of the unit. BOTH grounds must be connected to earth ground to comply with CE
performance requirements. Ground wires should be kept as short as possible and tied to a common cabinet/equipment ground
point. It is recommended to use #14AWG stranded wire for the chassis ground.
