Appendix C Connecting to DC Power Connecting to DC Power Wiring the DC-Input Power Source Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 Caution You must connect the Catalyst 3560V2-24TS-SD switch only to a DC-input power source that has an input supply voltage from -36 to -72 VDC. If the supply voltage is not in this range, the switch might not operate properly or might be damaged. Caution The switch must be installed with 5 A-branch-circuit protection. Note This installation must comply with all applicable codes. To wire the switch to a DC-input power source, follow these steps: Step 1 Apply tape to the circuit-breaker switch handle, and move the circuit-breaker handle to the off position. Step 2 Locate and remove the terminal block plug (see Figure C-5). Figure C-5 Terminal Block Plug 60530 Step 3 Step 4 Identify the positive and negative feed positions for the terminal block connection. The wiring sequence is positive to positive and negative to negative for both the A and the B feed wires. The switch rear panel identifies the positive and negative positions for both the A and B feed wires. Using a 18-gauge wire-stripping tool, strip each of the four wires coming from the DC-input power source to 0.27 inch (6.6 mm) ± 0.02 inch (0.5 mm), as shown in Figure C-6. Do not strip more than 0.29 inch (7.4 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave exposed wire from the terminal block plug after installation.

Wiring the DC-Input Power Source
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit.
Statement 1003
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Caution
You must connect the Catalyst 3560V2-24TS-SD switch only to a DC-input power source that has an
input supply voltage from –36 to –72 VDC. If the supply voltage is not in this range, the switch might
not operate properly or might be damaged.
Caution
The switch must be installed with 5 A-branch-circuit protection.
Note
This installation must comply with all applicable codes.
To wire the switch to a DC-input power source, follow these steps:
Step 1
Apply tape to the circuit-breaker switch handle, and move the circuit-breaker handle to the off position.
Step 2
Locate and remove the terminal block plug (see
Figure C-5
).

Step 3
Identify the positive and negative feed positions for the terminal block connection. The wiring sequence
is positive to positive and negative to negative for both the A and the B feed wires. The switch rear panel
identifies the positive and negative positions for both the A and B feed wires.
Step 4
Using a 18-gauge wire-stripping tool, strip each of the four wires coming from the DC-input power
source to 0.27 inch (6.6 mm) ± 0.02 inch (0.5 mm), as shown in
Figure C-6
. Do not strip more than 0.29
inch (7.4 mm) of insulation from the wire. Stripping more than the recommended amount of wire can
leave exposed wire from the terminal block plug after installation.
