400/450 Series Connector Strip Assembly Instructions
Electrical Connections
-From End Plates Each end plate has
(4) .125” diameter pilot holes. These pilot
holes act as centers for optimal positioning of
holes up to 2.5” in diameter for attaching wiring
strain relief devices into connector strips. Use
the pilot hole to drill the required size for a
Greenlee® or equivalent punch to obtain
proper hole size for your installation require-
ments. Use 1st hole from the top for data in-
put, and 3rd hole from the top for AC power
connection.
WARNING: This equipment MUST be grounded. Never defeat the ground conductor or
operate the equipment in the absence of a suitably installed ground conductor. Contact
the appropriate electrical inspection authority or an electrician if you are uncertain that
suitable grounding is available.

Attaching Wires to Spring Clamp Type Terminal Blocks. (15A-50A Circuits Only)
20 Amp circuits are gray in color with white marking labels that accept up to maximum
8 AWG wire.
Step 1. Insert 1/8” wide flat blade screwdriver (supplied) into the square slot and push
all the way down so that screwdriver bottoms out.
Step 2. Insert the stripped wire into the oblong shaped hole.
Step 3. Remove screw driver to release spring clamp.
Step 4. Repeat steps 1-3 for all remaining connections.
DIN Rail Terminal Block System
The connector strip uses a 35MM
DIN rail modular terminal block sys-
tem. Terminal blocks range from 15
amps to 115 amps depending on
product configuration when ordered.

Note: Not all terminal blocks listed in chart below
may be present in connector strip.
**Note: 50A spring clamp terminal blocks are used for 20A circuits.
The upsizing allows for contactors to use #10AWG or #8 AWG line
feed wire. All load side components are rated at 20A.
