Installing A Power Supply - GE VersaMax Manual

Installing a Power Supply

I/O and option modules receive power for their operation from the CPU, NIU, or
Expansion Receiver Module via the mating connector on the carrier. The number of
modules that can be supported depends on the power requirements of the modules (which
are listed in the individual module specifications).
Power Supply Booster Carriers can be used as needed to meet the power needs of all
modules. The AC or DC Power Supply on the CPU or NIU and the Power Supply that
resides on the Booster Carrier must share the same external power source.
In some cases, the field devices served by an I/O module require additional AC or DC
power, which must be provided using an "external" power supply. Specifications and
connection details for such external power supplies are given in the module specifications
in this manual.
Installing a Power Supply Module
The power supply module installs directly on top of a CPU, NIU, ERM, or booster carrier.
The latch on the power supply must be in the unlocked position.
Align the connectors, tab, and latch post on the power supply to be parallel with the CPU,
NIU, ERM, or carrier. Press the power supply module down firmly, until the two tabs on
the bottom of the power supply click into place. Be sure the tabs are fully inserted in the
holes in bottom edge of the CPU, NIU, ERM, or booster carrier.
Turn the latch to the locked position to secure the power supply in place.
Note: The VersaMax power supply is not hot-swappable. Hot inserting or extracting the
power supply is an improper method to power-down or power-up. Hot inserting the power
supply can cause a "Corrupted User Memory Fault" condition. Power-cycling should only
be accomplished by switching the main power going into the power-supply.
