Place the Power Supplies
ATTENTION
!
Turn off the power supply module before
removing it from or inserting it into a chassis.
Failure to observe this warning could alter
processor memory, damage module circuitry, and
cause unintended operation which could possibly
cause injury to personnel.
You can place these power supply modules into any I/O module slot
in any current chassis (1771-A1B, -A2B, -A3B, -A3B1,
-A4B, -PSC).
The primary requirement for placing redundant power supplies is the
need to allocate 2 to 4 adjacent slots in your 1771 I/O chassis for
the modules.
IMPORTANT
You cannot use the 1771-P4R, -P6R power
supplies with series A 1771 I/O chassis.
!
WARNING
When you insert or remove the module while
backplane power is on, or you connect or
disconnect the wiring with field power applied, an
electrical arc can occur. This could cause an
explosion in hazardous location installations. Be
sure power is removed or the area is nonhazardous
before proceeding.
The power supply is a modular component of the 1771 I/O system
requiring a properly installed system chassis. Refer to publication
1771–IN075 for detailed information on acceptable chassis, and
proper installation and grounding requirements. Limit the adjacent
slot power dissipation to 10W maximum.
