This chapter is provided for qualified personnel to install the product, which shall be mounted in a clean and dry
environment.
NOTE: To aid the user with installation, frequent reference is made to foldout drawings located at the rear of the manual.
3.1 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.
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.
Use OSHA approved insulated hand tools.
3.2 Tools Required
Various insulated tools are essential for product installation. Use this list as a guide:
• Philips head screwdriver, #2 (tip size 3/16”)
• Digital voltmeter equipped with test leads
• Cutters and wire strippers
• Crimping tool (optional for large gauge wire)
• Socket and rachet set (Imperial measure).
3.3 Shelf Preparation/Mounting
The 020-671-20 shelf has been designed for mounting in a standard 23” relay rack. See drawing 020-671-06.
The 020-675-20 shelf has been designed for mounting in a standard 19” relay rack. See drawing 020-675-06.
Mounting brackets accommodate either 1” or 1-3/4” rack spacing. The shelf should be mounted to the rack using
at least two #12 – 24 x 1/2” screws in each bracket. Philips-type screws and screwdriver should be used to
eliminate the possibility of slippage and scratching of the unit’s exterior. Washers (such as internal tooth) or
special screws that are designed to cut through the painted surface should be used to ensure a good chassis
ground.
Consult the drawings located at the rear of this manual and proceed to the next section for wiring connections.
