4 Installation
This chapter is provided for qualified personnel to install the product, which shall be mounted in a clean and dry
environment. For battery installation refer to the manufacturer’s guidelines for more specific information.
NOTE: To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.
4.1 Safety Precautions
DANGER
Hazardous voltages are present at both the input and the output of power systems. The DC output
from the rectifiers and the battery system is at a lethal potential and has a high short circuit
current capacity that can cause electrocution, severe burns and electrical arcing.
CAUTION
Circuit breaker must be off before removal or insertion.
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.
4.2 Tools Required
Various insulated tools are essential for product installation. Use this list as a guide:
•
Philips head screwdriver, #3 (tip size 1/4")
• Slot head screwdriver (blade size 1/8")
• 7/16" hex socket with drive
• 9/16" hex socket with drive
• Digital voltmeter equipped with test leads
• Cutters and wire strippers #16 to #26 AWG (1.5 to 0.14mm²).
4.3 Preparation/Mounting
The DCP03 300A Distribution Center occupies three (3) vertical rack spaces. The rack mounting “ears” are
universal for 19" or 23" racks and can be center or flush mounted. See drawing 020-702-06.
Position the ears as desired and secure the DCP03 to the rack using at least three #12-24x1/2" screws on each
side. A captive type of drive, such as the Philips head, is preferred to reduce the possibility of slippage and
scratching of the unit’s exterior.
NOTE: The DCP03 requires at least 1RU (1.75") of space above the unit for tooling access to the load breaker ground
connections. Ensure that at least 1RU of space is open in the relay rack above the DCP03.
