1.2.4 Transport and storage
During transport and storage, devices must be protected against undue stress (mechanical loads, temperature,
moisture, corrosive atmospheres, etc.).
Devices contain components sensitive to electrostatic charges that can be damaged by inappropriate handling. It
is therefore necessary to provide the required protective measures against electrostatic discharge when installing
or removing these devices (see also section 1.2.3 "Protection against electrostatic discharge").
1.2.5 Installation
•
Installation must be performed according to this documentation using suitable equipment and tools.
•
Devices are only permitted to be installed by qualified personnel without voltage applied.
•
General safety guidelines and national accident prevention regulations must be observed.
•
Electrical installation must be carried out in accordance with applicable guidelines (e.g. line cross sections,
fuses, protective ground connections).
•
Take the necessary steps to protect against electrostatic discharges (see section 1.2.3 "Protection against
electrostatic discharge").
1.2.5.1 Inserting and removing I/O modules while the controller is running
I/O modules may be connected and disconnected while the controller is running under the following conditions:
•
Connectors are not allowed to carry voltages and must be removed.
•
Replacing a module during operation must be supported by the software; otherwise, disconnecting a mod-
ule will cause an emergency stop of the controller.
