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 Webpages, 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 cannot 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 (page 95).
