PTX1000 DC Power Cable Specifications
PTX1000 DC power supplies require a D-Sub 3W3- type connector. The three pins on the connector
provide –48 VDC input (–), return (+), and ground connections to the power supply.
NOTE: The optional right-angle DC power cables, CBL-JNP-PWR-DSUB2 and
CBL-JNP-PWR-DSUB3, do not include a ground connection wire.
Regardless which DC power cable you use, you must connect the PTX1000 to earth ground
before you connect it to to power, using the procedure described in “Connecting the PTX1000
to Ground” on page 81.
DC power cables, each approximately 13.1 ft (4 m) long, are supplied with the PTX1000. The provided
cables include the three-pin connector on one end and insulated wires at the opposite end, for connection
to the site’s DC power distribution system.
Table 16 on page 47 lists the specifications for the PTX1000 DC power cables.
