IOLAN SDS2 LA/LE Hardware Installation Guide
Connecting the Hardware
Terminal block connector
Either the barrel or TB (Terminal Block) can be used to power the SDS2 L.
Plug the power adapter into a power socket and connect the barrel connector end into
the IOLAN SDS2 L. The IOLAN SDS2 L will perform a power up sequence. The Power/
Ready LED should show a solid green. See LED Indicators for power up sequence.
Connecting the terminal block connector
1. Ensure power is NOT applied to the wires prior to connection.
2. On each end wire (12‐20 AWG), remove the insulation from the copper wire 5 mm (3/
16 of an inch).
3. Loosen the left screw on the top of the terminal connector block, then insert your
positive (+) wire into the left terminal and screw it down tight (.51Nm torque).
Loosen the right screw on the top of the terminal connector block, then insert your
negative (‐) wire into the right terminal and screw it down tight (.51Nm torque).
4. Re‐insert the terminal block connector if removed.
5. Connect the Wi‐Fi antenna/s by simply screwing the antenna/s onto the connectors
on the IOLAN.
6. Connect the Ethernet cable from the RJ‐45 plug (10/100/1000) to the HUB or switch
that will provide network connectivity (if applicable to your application).
7. The console dip switch on the IOLAN should be set to the down position for serial
mode.
8. Connect the power cord strain relief, if desired. (Figure 2)
9. Connect the grounding lug (not provided) to the grounding screw, if desired. (Figure
1)
10. Turn on power at source. See LED Indicators for power up sequence.
Grounding and Power Cord Relief clip
If your installation requires additional grounding, follow this procedure.
Grounding the chassis requires the following items:
• One grounding lug (not provided)
• One 12AWG wire (not provided)
Follow the manufacturers instructions for attaching the ground wire to the grounding
lug.
1. Attach the grounding lug to the chassis and secure with the grounding screw
provided. See Figure 1.
2. Attach the power cord relief clip as shown in Figure 2.
