tential equalization must be provided when working on the device (antistatic
protection).
Before connecting or disconnecting additional devices from the data outputs,
the device must be disconnected from the mains.
2.4.4 Supply voltage connection
Supply voltage U
DC
= 24V +10 %/-15 %
The max. power consumption is 9W.
The connection diagram is located on the right side of the housing.
For a connection to 230/115 V alternating current, an external power supply is
required.
2.4.5 Protective ground connection
The protective ground connection is made via the mounting rails.
2.4.6 RF interference suppression
The device is intended for use in an industrial environment. Operation of this
device in a residential environment is likely to cause radio frequency interfer
ence, see ChapterRF interference suppression. In this case, the operator may
be required to take appropriate measures.
2.4.7 Failure and excessive stress
If there is any reason to assume that safe operation of the device is no longer
ensured, shut it down and make sure it cannot be used.
