Cisco Systems IE20004TSL, IE20004TSB manual Connecting the Power Converter to a DC Power Source

Chapter 2 Switch Installation

Connecting to Power

Step 4 Insert the line and neutral wire leads into the terminal block line and neutral connections. See Figure 2-9, items 2 and 3. Make sure that you cannot see any wire lead. Ensure that only wire with insulation extends from the connectors.

Step 5 Tighten the line and neutral terminal block screws.

Note Torque to 8 in.-lb, not to exceed 10 in-lb.

Step 6 Replace the plastic cover over the terminal block.

Step 7 Connect the other end of the wiring to your AC power source.

Connecting the Power Converter to a DC Power Source

You can also connect the power converter to a DC power source. Several power supplies can be used. Refer to Table 2-1 on page 2-13for the appropriate DC input ratings.

Note Use copper conductors only, rated at a minimum temperature of 167°F (75°C).

Step 1 Measure a single length of stranded copper wire long enough to connect the power converter to the earth ground. The wire color might differ depending on the country that you are using it in.

For connections from the power converter to earth ground, use shielded 18-AWG stranded copper wire, such as Belden part number 9912 or the equivalent.

Step 2 Measure a length of twisted-pair copper wire long enough to connect the power converter to the DC power source.

For DC connections from the power converter to the DC source, use 18-AWG twisted-pair copper wire, such as Belden part number 9344 or the equivalent.

Step 3 Using a 18-gauge wire-stripping tool, strip the ground wire and both ends of the twisted pair wires to

0.25inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch (6.8 mm) of insulation from the wires. Stripping more than the recommended amount of wire can leave exposed wire from the power and relay connector after installation.

Step 4 Connect one end of the stranded copper wire to a grounded bare metal surface, such as a ground bus, a grounded DIN rail, or a grounded bare rack.

Step 5 Insert the other end of the exposed ground wire lead into the earth-ground wire connection on the power converter terminal block. Only wire with insulation should extend from the connection. See Figure 2-10, item 1. Note that the position of the power converter may vary on different switch models.

Step 6 Tighten the earth-ground wire connection terminal block screw.

Note Torque to 8 in.-lb, not to exceed 10 in-lb.
