6� System Installation
This chapter is provided for qualified personnel to install the system and provides cabling details and notes on cable
sizing for DC applications.
6�1 General Instructions
Connections to the converter system must comply with all the local codes and ordinances.
6�2 Safety Precautions
WARNING!
The DC input to the modules (and the converter system) – though not dangerous in volt-
age – has a high short circuit current capacity that may cause severe burns and electri-
cal arcing.
Before working with any live power system, take the following 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 metallic 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.
6�3 Tools Required
Various insulated tools are essential for product installation. Use the following as a guide:
• Phillips head screwdriver, #2 (tip size 3/16")
• Slot head screwdriver (blade size 1/8")
• Digital voltmeter equipped with test leads
• Cutters, crimpers, and wire strippers 0.25 to 10mm

6�4 Setting the Shelf ID
6�4�1 Rack Mounting
NOTE:
Use thread forming screws with paint piercing washers to connect the shelves and fan
assembly to the frame.
Use universal mounting brackets to mount the eLimiter+ shelf in a 19" or 23" rack. For bracket part numbers see
section "4.4.2 Mounting 19" Equipment in a 23" Rack" on page 15.
When the eLimiter+ shelf is installed in open-style rack, the use of base extenders is required to comply with
GR-63 Section 3.4 requirement. Base extenders are commercially available to protect equipment that protrudes
beyond the standard rack base.
For Alpha-supplied racks, the recommended base extension part is #5901537-001 which can be ordered sepa-
rately.
Set the rotary dial to a unique shelf
ID before mounting. Do not use 0.
