2.3.1 Electrical Shock Hazard
The danger of a lethal electrical shock caused by parts with more than 50V may occur if you
power a PLC power supply module when its housing is open.
 HAZARDOUS VOLTAGE is present inside of a powered PLC power supply module.
 Strictly obey all safety rules provided by the device manufacturer in the documentation.
 Disconnect the network power (power plug) from the power supply module before you
disconnect the PLC module from the backplane.
 When you disconnect the PLC module from the power supply module, use end cap
terminators and close the power supply module housing.
An electrical shock is the result of a current flowing through the human body. The resulting
effect depends on the intensity and duration of the current and on its path through the body.
Currents in the range of approximately ½ mA can cause effects in persons with good health,
and indirectly cause injuries resulting from startling responses. Higher currents can cause
more direct effects, such as burns, muscle spasms, or ventricular fibrillation.
In dry conditions, permanent voltages up to approximately 42.4 V peak or 60 V are not
considered as dangerous if the contact area is equivalent to the size of a human hand.

2.3.2 Communication Stop During Firmware Update
If you plan a firmware update via the ProSoft web pages, please yield:
 During the firmware update procedure, a device reset is performed and stops all module
communication functions with network devices. An unintended plant stop can cause
personal injury.
 Initiating a device reset causes a device reboot. A reboot stops all communication
immediately.
 Personal injury by consequence of careless use caused plant stop can not be excluded.
 All fieldbus devices should be placed in a fail-safe condition under direct supervision
before starting a firmware update.
 Before you initiate a reset, make sure your system is in an idle state and operating under
maintenance conditions in order to prevent personal injury.
 Stop the PLC program before you start the firmware update.
More firmware update information is located at Firmware Update.
