Wiring with Spade Lugs
The diameter of the terminal screw head is 5.5 mm (0.220 in.). The input and
output terminals of the MicroLogix 1500 base unit are designed for a 6.35mm
(0.25 in.) wide spade (standard for #6 screw for up to 14 AWG) or a 4 mm (metric
#4) fork terminal.
When using spade lugs, use a small, flat-blade screwdriver to pry the finger-safe
cover from the terminal blocks as shown below. Then loosen the terminal screw.
Finger-Safe
Cover
Using Surge
Suppressors
Inductive load devices, such as motor starters and solenoids, require the use of
some type of surge suppression to protect and extend the operating life of the
controller’s output contacts. Switching inductive loads without surge suppression
can significantly reduce the life expectancy of relay contacts. By adding a
suppression device directly across the coil of an inductive device, you prolong the
life of the output or relay contacts. You also reduce the effects of voltage transients
and electrical noise from radiating into adjacent systems.
The following diagram shows an output with a suppression device. We recommend
that you locate the suppression device as close as possible to the load device.

Suitable surge suppression methods for inductive ac load devices include a varistor,
an RC network, or an Allen-Bradley surge suppressor, all shown below. These
components must be appropriately rated to suppress the switching transient
characteristic of the particular inductive device. See the table on page 3-5 for
recommended suppressors.

Surge
Suppressor
If you connect an expansion I/O triac output to control an inductive load, we
recommend that you use varistors to suppress noise. Choose a varistor that is
appropriate for the application. The suppressors we recommend for triac outputs
when switching 120V ac inductive loads are a Harris MOV, part number V175
LA10A, or an Allen-Bradley MOV, catalog number 599-K04 or 599-KA04.
Consult the varistor manufacturer’s data sheet when selecting a varistor for your
application
For inductive dc load devices, a diode is suitable. A 1N4004 diode is acceptable for
most applications. A surge suppressor can also be used. See the table on page 3-5
for recommended suppressors.

Sinking and Sourcing
Circuits
Any of the MicroLogix 1500 DC embedded input groups can be configured as
sinking or sourcing depending on how the DC COM is wired on the group. See
pages 3-11 through 3-14 for sinking and sourcing wiring diagrams.
Type
Definition
Sinking Input
The input energizes when high-level voltage is applied to
connection of a PNP sourcing device the input terminal (active high). Connect the power supply
VDC (-) to the DC COM terminal.
The input energizes when low-level voltage is applied to
Sourcing Input
connection of an NPN sinking device the input terminal (active low). Connect the power supply
VDC (+) to the DC COM terminal.

Follow the procedure below to ensure proper replacement battery installation.
IMPORTANT
Do not remove the permanent battery when installing
replacement battery.
1. Insert battery into replacement battery pocket with wires facing up.
2. Insert replacement battery wire connector into connector port.
