For example purposes, this section describes how to use a 1606-XLE80E,
Class 2 switched-mode power supply with the FP+ and FP- terminals. The
exact steps for other external power supplies can vary from the steps that
are described here.
Complete these steps to connect power to the CompactLogix 5370 series B
L16ER, L18ER, L18ERM, and series A L19 controllers.
1.
Verify that the separate external 24V DC power source that powers the
CompactLogix 5370 L1 controller is not powered.
2.
Connect wires to the + and - connections on the external 24V DC power
source.
