3. Installation
Connecting Chassis Grounding
The system contains gaskets at the chassis and board level to guard against electromagnetic
interference (EMI). Each of the
chassis’ individual components make contact with the gaskets and to the
PE-stud inside the rear panel.
The guide rails are also fitted with electrostatic discharge (ESD) contacts for each blade. These ESD
contacts ensure that the boards are fully discharged to prevent static caused by static as they are
plugged into the chassis.
Caution!
The chassis is designed in accordance with protection class1l! lt must therefore
be operated with protective earth/GND connection. Use only a three conductor
AC power cable with a protective earth conductor that meets the IEC safety
standards!
There is a 4 mm stud at the rear panel. This stud is only for potential equalization. Grounding is achieved
through the protective earth conductor of the power cable!
Inspecting the Chassis Components
During the course of handling, shipping, and assembly, pins, shrouds, mounting screws, fans and other
items can become damaged and/or loose.
WARNING:
Before utilizing the chassis, perform a thorough inspection to ensure the
chassis and its components are not damaged.
•
To inspect the chassis:
1. Visually inspect the chassis to ensure that all of the connector pins are straight, screws are tight, and
so on.
2. Check to ensure none of the EMI gaskets are damaged.
Protection Against Electromagnetic Interference
The chassis contains gaskets at the shelf and board level to guard against electromagnetic interference
(EMI). Ensure that the chassis is grounded and that each of the chassis individual components make
contact with the gaskets.
Follow the proper grounding and ESD handling procedures.
