Connecting/Removing Devices
To avoid injury and damage to the hardware, please observe the following pre-
cautionary measures:
• Do not apply any voltages to the connectors of the ES4408.1 Load Chassis
which do not correspond to the specification of the relevant connector.
For details of the exact specification of the I/O hardware, consult the man-
ual of the relevant board.
• Please observe the maximum permissible currents of the individual signal
lines.
• Do not connect or remove any devices when the ES4408.1 Load Chassis
or external devices are powered on.
• Make sure that all connectors are inserted straight to ensure that the pins
are not bent.
2.2.1
Opening the Rear of the Housing
The rear of the ES4408.1 Load Chassis must only be opened by qualified techni-
cal personnel!
Disconnect from the power supply by removing the power cable; then wait a few
minutes until all components (e.g. power supply unit, capacitors) are discharged.
2.2.2
Installing and Removing Hardware
To avoid the hardware being damaged by electrostatic discharge, please observe
the following precautionary measures:
• The boards in the ES4408.1 Load Chassis can be damaged or even
destroyed by electrostatic discharge.
• Boards should only be taken from their package, configured and installed
at a working place that is protected against static discharge. Avoid touch-
ing the board’s connectors and any conductors on it.
DANGER!
As long as the ES4408.1 Load Chassis is connected to the power
supply, you risk getting an electric shock!
CAUTION!
If cards are unlocked (e.g. during setup or calibration) but not com-
pletely removed from the housing, they nevertheless have to be pul-
led out of the housing so that the distance between the card and the
backplane of the housing is at least 1 cm! Otherwise there could be
contacts between the cards which could then be destroyed as a
result.
