Installation
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 drawings located at the rear of the manual.
5.1
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.
Metallic tools must be insulated.
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.
5.2
Shelf Preparation/Mounting
The 19” shelf has been designed for flush mounting in a standard EIA relay rack. Options for mid-mounting in a
19” or 23” rack are also available.
The 23” shelf may be flush or mid-mounted in a 23” relay rack.
NOTE:
The shelf shall be mounted 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 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.
5.3
Rectifier Module Insertion/Removal
Insert by placing the rectifier module on the shelf bottom and sliding the module into the rear connector (inside of
the shelf). Apply pressure on the module handle to engage the rear connector in the shelf receptacle.
NOTE:
It is recommended that the first module be inserted into the front leftmost position using the side of the shelf (or
the optional shelf-mounted controller) as a guide. Subsequent modules may be inserted using the previous
module as a guide.
Tighten the screw on the bottom of the faceplate to secure the module to the shelf.
NOTE:
Do not force a module into position if it does not seat properly. All modules are keyed to ensure that the correct
module (voltage/polarity) type is used.
To remove a module, loosen the screw on the bottom of the faceplate. Grasp handle and pull out, sliding the
module away from the rear connector and out of the shelf.
