WARNING: Make sure that the external power source is turned OFF before attempting to connect power leads to the industrial switch. Failure to observe this warning could result in an electrical shock.

WARNING: The SIBTF10xx-1xx-Mx is a class I device. It has a provision for protective earth grounding. Equipment grounding is vital to ensure safe operation. The SIBTF switch must be earth grounded during and after installation. Failure to observe this warning could result in an electric shock.

Note: DO NOT use bare (exposed) or un-lugged power-source wires to connect to the industrial switch.

Connecting primary power

The industrial switch is designed to accommodate 48 – 170VDC or 90 – 125VAC, 50/60 Hz input power via its primary terminal block (TB).

To provide power to the industrial switch via the primary TB, view Figure 5, and then do the following:

1.Verify that the external power source is turned OFF and disconnect.

2.Loosen the grounding screw and then connect the power source functional-ground lead to the grown screw, as shown in Figure 5. Tighten the screw to secure.

3.Loosen the TB screw marked “-” and then connect the power source neutral or (-) negative lead to the TB negative terminal, as shown in Figure 5. Tighten the screw to secure.

4.Loosen the TB screw marked “+” and then connect the power source line phase or positive (+) lead to the TB positive terminal, as shown in Figure 5. Tighten the screw to secure.

5.Re-connect and turn ON the external power source.

6.Verify that the industrial switch has powered up by observing the illuminated “Power Good” LED on the front panel.

Note: DO NOT use bare (exposed) or un-lugged power-source wires to connect to the SIBTF10xx-10x-MR industrial switch.

Connecting auxiliary power

The SIBTF10xx-10x-MR switches support a redundant power supply. If the primary power source fails, the auxiliary power source supplies power to the industrial switch.

To provide auxiliary power to the industrial switch, view Figure 6 and do the following:

1.Verify that the external power source is turned OFF and disconnected.

2.Loosen the grounding screw and connect the power source functional-ground lead to the grown screw, as shown in Figure 6. Tighten the screw to secure.

3.Loosen the TB screw marked “-” and then connect the power source neutral or (-) negative lead to the TB negative terminal, as shown in Figure 6. Tighten the screw to secure.

4.Loosen the TB screw marked “+” and then connect the power source line phase or positive (+) lead to the TB positive terminal, as shown in Figure 6. Tighten the screw to secure.

5.Re-connect and turn ON the external power source.

6.Verify that the industrial switch is powered UP: auxiliary “Power Good” LED on the lower front panel will be ON.
