Some components of the ES4435.1 Current Source Load Board may
be damaged or even destroyed by static discharge. Leave the board in
its transport package until you want to install it.
The ES4435.1 Current Source Load Board should only be taken from
its package, configured and installed at a working place that is pro-
tected against static discharge.
The components, connectors and conductors of the ES4435.1 Cur-
rent Source Load Board may carry dangerous voltages. These voltages
may even exist if the ES4435.1 is not installed in the ES4408.1 Load
Chassis or the ES4408.1 Load Chassis is powered off.
Make sure the ES4435.1 is protected against contact during opera-
tion.
If cards are unlocked (e.g. during setup or calibration) but not com-
pletely removed from the housing, they nevertheless have to be
pulled 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.
