5 Installation
NOTE
: This power system is suitable for installation in Network Telecommunication Facility locations
where the NEC applies, and in OSP applications.
This chapter is provided for qualified personnel to install the product. Mount the unit horizontally in a
clean and dry environment.
NOTE
: Drawings are located at the rear of the manual.
This system is designed to be installed in a restricted access location that is inaccessible to the general
public.
5.1 Safety Precautions
WARNING
: Hazardous voltages are present at the input of power systems. The DC output from the recti-
fiers and battery system, though not dangerous in voltage, has a high short circuit current capacity that
may cause severe burns and electrical arcing.
Before working with any live battery or power system/distribution center, follow these precautions:
• Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.
• Wear safety glasses with side shields (and prescription lenses if necessary) at all times during
installation.
• Use insulated hand tools.
The installer should follow all applicable local rules and regulations for electrical and battery installa-
tions; e.g., CSA, UL, CEC, NEC, OSHA, and local fire codes.
5.2 Shelf Preparation/Mounting
NOTE
: The shelf is designed for horizontal mounting in a clean and dry environment. Allow at least 1.75"
of free space in front of the unit for unrestricted cooling airflow.
Each shelf has been designed for center mounting in a 19" or 23" rack (or flush mount for 1RU shelves).
See drawings at the end of this manual.
Mounting brackets accommodate either 1" or 1¾" rack spacing. Mount the shelf to the rack using at
least two #12 – 24 x ½" screws in each bracket. Use Phillips-type screws and screwdriver to eliminate
the possibility of slippage and scratching of the unit’s exterior.
An electrical conducting path must exist between the unit’s chassis and the metalwork of the enclosure
in which it is mounted or a grounding conductor. The electrical continuity requirement can be met by the
use of thread-forming type unit mounting screws and star washers that remove any paint or
non-conductive coatings and establish metal-to-metal contact.
5.3 Module Insertion/Removal
The rectifier is plug and play. When a rectifier module is added to the system, the controller will detect
and update the inventory automatically. Replacing an installed rectifier requires a manual
Inventory
Update at the controller to clear the removed rectifier from its current list of rectifiers.
