DC Power Cable (OT and Cord End Terminals)

DC Power Cable (OT and Cord End Terminals)

Connectors and power capacity of a power cable must match the device on which the cable is used. Therefore, a device must use the power cables delivered with it.

Types of DC Power Cables

DC power cables of fixed lengths (integer number of meters) are delivered with switches. Cut the DC power cables into appropriate lengths based on actual situations in your site.

DC power cables include -48 V power cables and RTN ground cables. The lengths and terminal types of DC power cables used between power distribution boxes and power distribution frames are determined by the site survey results. DC power cables with OT terminals are connected to power modules, as shown in Figure 9-1.

The cord end terminal is connected to a power distribution box or power distribution frame, whereas the OT terminal can be connected to terminals on a 2200 W DC power module.
