!
ATTENTION:
Electrostatic discharge can damage integrated
circuits or semiconductors if you touch backplane connector pins.
Follow these guidelines when you handle the power supplies.
• Touch a grounded object to discharge static potential.
• Do not touch the backplane connector or connector pins.
• Do not touch circuit components inside the power supply.
• If available, use a static-safe work station.
• When not in use, keep the power supplies in their static-shield
packaging.

Install the Chassis Interconnect Cable (Optional)
To connect up to three SLC 500™ chassis together, install the chassis
interconnect cable before installing the power supply
.
Power Supply Installation
1. Align the circuit board of the power supply with the card guides on the left
side of the chassis
.
2. Slide the power supply in until it is flush with the chassis. Then fasten the
power supply to the chassis
.
SLC 500 chassis/A
For more information, see the
SLC 500 Modular Style
Installation and Operation
Manual
(publication 1747-6.2).
Use these screws to fasten the
power supply to the chassis.

Power Supply Wiring
1. Place the input voltage jumper to match the input voltage. (This does not
apply to the 1746-P3, -P5, -P6, and -P7 power supplies, which do not have a
jumper.)
2. Connect the ground screw of the power supply to the nearest ground or
ground bus. Use a #14 AWG wire and keep the leads as short as possible.
The 1746-P4 is shown below.
Refer to page 6 for special wiring
considerations for the 1746-P3.
!
ATTENTION:
Set the input jumper before applying power.
Hazardous voltage is present on exposed pins when power is
applied; contact with the pin may cause injury to personnel.

3. Connect incoming power.
!
ATTENTION:
Turn off incoming power before connecting
wires; failure to do so could cause injury to personnel and/or
equipment.
!
ATTENTION:
Your SLC 500 power supply can be damaged by
voltage surges when switching inductive loads such as motors,
motor starters, solenoids, and relays. To avoid damage to your SLC
500 power supply in these applications, it is strongly reccommended
than an isolation transformer be used to isolate the power supply
from harmful voltage surges.

1746-P3 Wiring Considerations
The information below describes special wiring considerations for the 1746-P3.
!
ATTENTION:
Any voltage applied to the 1746-P3 DC NEUT
terminal will be present at the SLC logic ground and the processor
DH-485 port. To prevent unwanted potentials across the logic
ground of the controller and/or damage to the SLC chassis, the DC
NEUTRAL of the external DC power source must be either isolated
from the SLC chassis ground or connected to earth ground as shown
in the following illustration.
Important:
SLC 500 Series A chassis (1746-A4, -A7, -A10, and -A13)
manufactured
before
November 1992 have a resistor between the
logic ground and chassis ground as the drawing on the following
page illustrates. This resistor could be damaged if the wiring
recommendation described within the attention box above is not
followed. See the figure on the following page for the location of
the resistor. SLC 500 Series A chassis (1746-A4, -A7, -A10, and
-A13) with a manufacture date of November 1992 or later do not
have this resistor. SLC 500 Series B chassis have a 1M
Ω
resistor
that limits the current between logic ground and chassis ground.

(Optional)
For the 1746-P1, -P2,-P4, -P5 and -P6 power supplies, use PWR
OUT +24V dc and PWR OUT COM terminals to power 24V dc sensors and
loads. The terminals on the 1746-P1, 1746-P2, 1746-P5 and 1746-P6
provide an isolated, nonfused 200 mA, 24V dc power supply. The terminals
on the 1746-P4 provide an isolated, nonfused 1A, 24V dc power supply.
(The 1746-P3 and -P7 power supplies do not provide for an external power
source.)

Power Supply Undervoltage Operation
SLC 500 controllers continue to operate (hold-up) for a short period of time if the
input voltage to the power supply drops below the recommended operating
voltage range. The controller continues to scan the user program and control I/O
during this time. CPU hold-up for each power supply is shown on pages 9 and 10.
SLC 500 controllers turn OFF (stop scanning and disable outputs) if input
voltage to the power supply is removed or drops below the recommended
operating range for a period exceeding the CPU hold-up time. The controller
resumes operation automatically when the input voltage is restored to normal.
If the input voltage to the 1746-P7 power supply falls into a range of 4 to 9V for
a period exceeding the CPU hold-up time, the controller turns OFF and will not
turn back ON until:
• input voltage is increased to 11V dc.
