DC Power Cable (OT and Cord End Terminals)
Types of DC Power Cables
DC power cables include a -48 V power return cable and a -48 V power cable. The -48 V power return cable is connected to a terminal marked RTN (+), and the -48 V power cable is connected to a terminal marked NEG (–).
Appearance and Structure
Figure 1 and Figure 2 show the appearance and structure of the 48 V power return cable and -48 V power cable.
A -48 V power return cable is black and is connected to the RTN(+) terminal of the DC power supply. A -48 V power cable is blue and is connected to the NEG(-) terminal of the DC power supply.
Connection
A DC power cable (with OT and cord end terminals) is connected to a DC power module with OT terminals as follows:
- The OT terminal is connected to the input port on the DC power module of the device.
- The cord end terminal is connected to an external power module.
