De-energizing the Add-on Card
Switch off the ES5300.1-A Housing or the ES5300.1-B Housing and external
power supplies, and unplug the power plug and other connectors attached to
the add-on card. Wait at least three minutes before removing the add-on card.
Approved Cables
The signal lines must not exceed a maximum length of 3 m.
Requirements for the installation location
Requirements for ventilation
Transport and Installation
To avoid damages to the hardware from electrostatic discharge, please observe
the following precautionary measures:
WARNING!
Fire hazard!
Use only approved cables for creating cable assemblies (e.g. for con-
necting the ECU and external loads). The cables used must, in partic-
ular, be suitable for the currents, voltages and temperatures which
occur and must be flame-retardant in accordance with one of the
following standards IEC60332-1-2, IEC60332-2-2, UL2556/
UL1581VW-1!
WARNING!
This is class A equipment. This equipment can cause radio interfer-
ence in residential areas. Should that be the case, the operator may
be requested to institute reasonable measures.
CAUTION!
The air circulation inside the ES5300.1-A Housing or the ES5300.1-B
Housing can be ensured only if all free slots are covered with front
plates. Otherwise, it may lead to overtemperatures and trip the over-
temperature protection of the ES5300.1-A or ES5300.1-B. For this
reason, install front plates in all free slots!
CAUTION!
Some components of the ES5321.1 can be damaged or destroyed by
electrostatic discharges. Leave the plug-in card in its transport pack-
aging until it is installed. Only remove, configure and install the
ES5321.1 at a workplace that is protected against electrostatic dis-
charges.
