To ensure your own personal safety and to avoid personal injury, you must
read, understand and follow the following safety instructions in this manual
and all warning messages before you install and operate the gateway.
Take care of the following safety measures before installing or uninstalling
the gateway:
First disconnect the power plug of the device.
·
Make sure that the device is disconnected from the power supply.
·
Cover or enclose neighboring units that are live.
·
Devices that are designed for mounting in housings or control cabinets
must only be operated and controlled after they have been installed with
the housing closed. Desktop or portable units must only be operated and
controlled in enclosed housings.
· Install automation devices and related operating elements in a way that
they are well protected against unintentional operation.
Emergency stop devices complying with IEC/EN 60204-1 must be
·
effective in all operating modes of the automation devices. Unlatching
the emergency-stop devices must not cause restart.
You must take safety precautions (emergency switching off) in the
·
external circuitry of the gateway and any power modules type EU5C-
SWD-PF1-1 or EU5C-SWDPF2-1 that are used. To do so, plan to
switch off the power supply to the contactor coils AUX.
Measures should be taken to ensure the proper restart of programs
·
interrupted after a voltage dip or failure. This should not cause
dangerous operating states even for a short time. If necessary,
emergency stop devices should be implemented.
· Wherever faults in the automation system may cause damage to
persons or property, external measures must be implemented to ensure
a safe operating state in the event of a fault or malfunction (for example,
by means of separate limit switches, mechanical interlocks etc.).
