INSTALLATION PROCEDURE
4. As the cable to be run between the PBX and the Rectifier, use a CV cable (600 V Crosslinked Polyethylene
Insulated PVC Sheathed Cable) as the circumstance permits. Compared with an ordinary IV cable (600 V
PVC Insulated Cable), the CV cable is stronger because of its thicker cover. Thus, it is suitable to run along
the free-access floor where it is difficult to protect the cable from damage.
Also, for easy identification of different cables, use cables of different colors as follows:
• –48 V: Blue (White)
• GND: Red (Black)
•E: Green
Note: The color shown in a bracket is applicable to the UL Specification.
