"4. As circumstances permit, use a CV cable (600 V Crosslinked Polyethylene Insulated PVC Sheathed Cable) between the PBX and the rectifier. A CV cable is stronger than an ordinary IV cable (600 V PVC Insulated Cable) because of its thicker cover. It is suitable to run along the free-access floor where it is difficult to protect the cable from damage. To easily identify different cables, use cables of different colors as follows: ? –48 V: Blue (White) ? GND: Red (Black) ? E: Green Note: The color shown in parentheses is applicable to the UL Specification."
Install the power equipment at the predetermined location using anchor bolts, etc. Install the framework for the backup batteries. Secure the framework using anchor bolts, etc. Check the cabling at the primary and secondary sides of the power equipment and the cabling to the batteries Confirm that the specifications of the customer-installed AC PDB (NFB capacity, voltage, phase, etc.) conform to the rectifier specifications. Confirm that the correct communication ground is available. Connect the input power cable and grounding cable to the rectifier. Supply electrolyte to each battery according to the battery’s specifications. Charge the batteries, after verifying that the rectifier is operating normally
