4 Installation
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 inaccessible to the general public.
4.1 Safety Precautions
WARNING
Hazardous voltages are present at the input of power systems. The DC output from the rectifiers
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 OSHA approved insulated hand tools.
The installer should follow all applicable local rules and regulations for electrical and battery installations;
e.g., CSA, UL, CEC, NEC, OSHA, and local fire codes.
4.2 Shelf Preparation/Mounting
Each shelf has been designed for center mounting in a 19" or 23" rack. See drawings 030-834-06, 030-
835-06, 030-845-06, or 030-851-06.
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.
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 Philips-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 nonconductive
coatings and establish metal-to-metal contact.
