Remove and Install the
Power Terminal Block The terminals are shipped with a power terminal block installed. You can remove
the terminal block for ease of installation, wiring, and maintenance.
The terminal blocks have different colors and markings for AC and DC power
connections. Always match the terminal block color to its mating connector. The
power terminal blocks are not intended for daisy chaining power.
Use a 0.6 x 3.5 mm flat blade screwdriver for terminal block wiring.

Follow these steps to remove the terminal block from a 400 or 600 terminal.
1. Insert the tip of a small, flat-blade screwdriver into the terminal block
access slot.
2. Gently pry the terminal block to rotate it away from the terminal; this
releases the locking mechanism.
Follow these steps to replace the terminal block.
1. Press terminal block base in first with block leaning outward.
2. Gently push the top of the terminal block to rotate it into place; it snaps
when seated.
WARNING: Explosion Hazard
If you connect or disconnect wiring while the power is on, an electrical arc can
occur. This could cause an explosion in hazardous location installations. Be sure
that power is removed and the area is nonhazardous before proceeding.
Failure to remove power can result in electrical shock or damage to the terminal.
