This chapter is provided for qualified personnel to install the shelf.
To aid the user with installation, frequent reference is made to drawings located at the rear of this manual.
3.1 Safety Precautions
WARNING
Hazardous voltages are present at the input of power systems. The DC output
from the rectifiers and the 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, the following precautions should be
followed:
• Remove all metallic jewelry; e.g., watches, rings, eyeglasses, necklaces.
• Wear safety glasses with side shields at all times during installation.
Insulated metallic tools shall be used.
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.
3.2 Shelf Preparation/Mounting
The shelf has been designed for mounting in a standard 23” relay rack. 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.
The shelf shall be mounted in a clean and dry environment. Allow at least 1.75” of free space around the unit
for unrestricted convection cooling airflow.
3.3 Module Insertion/Removal
Insert by placing the module on the shelf bottom and sliding the module into the rear connectors (inside of the
shelf). Apply pressure on the handles to engage the rear connector in the shelf receptacle. Tighten the screw on
the bottom of the faceplate to secure the module to the shelf.
WARNING
Do not force a module into position if it does not seat properly. All modules are
keyed to ensure that the correct module type is used.
To remove modules, loosen the screw on the bottom of the faceplate. Grasp handle and pull out, sliding the
module away from the rear connectors and out of the shelf.
Consult the drawings located at the rear of this manual and proceed to the next section for wiring connections.
