KTI Networks KSD-800M manual Applying Power, Using Terminal Blocks

2.5 Applying Power

The power specifications of the switch are:

Operating Voltage	+7 ~ +30VDC
Power Consumption	Max. 8.3W @30VDC

The switch provides two types of power interfaces, terminal block and DC power jack for receiving DC power input from external power supply.

Using Terminal Blocks

Either DC1 interface or DC2 interface can be used to receive DC power from an external power system. Or, DC2 also can be used to deliver the power received on DC1 to next switch in cascading way.

DC1 + Vdc Positive (+) terminal

DC1 - Vdc Negative (-) terminal

DC2 + Vdc Positive (+) terminal

DC2 - Vdc Negative (-) terminal

Three 2P terminal plugs are provided together with the switch. Two of the three plugs are used for DC1 and DC2 interfaces respectively. The plug is shown below:

Power wires : 24 ~ 12AWG (IEC 0.5~2.5mm2)

Install the power source wires with the plug properly. Then, plug in DC1 contacts. If cascading the power to next switch device is needed, install the power wires and plug for another switch. Then, use DC2 contacts.

Note: Only up to four device units can be cascaded to receive power from one main power input source.
