Some machine fabrication environments may accidentally cause conductive debris
to fall through the DL105 cooling vents and into the unit. All DL105 units come with a
protective sheet wrapped around the unit, covering the cooling vents. However, it
must be removed before electrical operation. Just unfasten the sheet on the right
side of the unit. The instructions are reprinted below for your reference.
CAUTION
1. DO NOT REMOVE THIS PROTECTIVE
SHEET until installation and wiring are completed.
2. REMOVE THIS SHEET before operation
to enable heat to escape for proper cooling.
The input and output terminal block connectors on the DL105 are identical. The
connectors are designed for easy removal with just a small screwdriver. The drawing
below shows the procedure for removal at one end. You’ll need to work at both ends
of the connector, so the ends move upwards approximately together.
Connector Removal
1.
Insert the screwdriver tip straight
into the opening at the corner of the
connector as shown.
2.
Pry screwdriver tip so connector
moves upward in direction of arrow.
The two terminal block connectors on DL105 PLCs have regular screw terminals,
which will accept either standard or #2 Philips screwdriver tips. You can insert one 14
AWG wire under a terminal, or two 16 AWG wires (one on each side of the screw). Be
careful not to overtighten; maximum torque is 6 inch/ounces.
Spare terminal block connectors and connector covers may be ordered by individual
part numbers:
