<1> Schematic Diagram of a Unit and Terminal Block Arrangement
To remove the front panel of the control box, unscrew the four screws and pull the panel forward and then down.
Important:
Power supply cables larger than 25 mm
2
in diameter are not connectable to the power supply terminal
block (TB2). Use a pull box to connect them.
<2> Installing the conduit tube
• Punch out the knockout hole for wire routing at the bottom of the front
panel with a hammer.
• When putting wires through knockout holes without protecting them
with a conduit tube, deburr the holes and protect the wires with
protective tape.
• If damage from animals is a concern, use a conduit tube to narrow the
opening.
