SAFETY
This option is specifically designed to be used with the ACS250
variable speed drive product and is intended for professional
incorporation into complete equipment or systems. If installed
incorrectly it may present a safety hazard. The ACS250 uses high
voltages and currents, carries a high level of stored electrical energy,
and is used to control mechanical plant that may cause injury. Close
attention is required to system design and electrical installation to avoid
hazards in either normal operation or in the event of equipment
malfunction.
System design, installation, commissioning and maintenance must be
carried out only by personnel who have the necessary training and
experience. They must read carefully this safety information and the
instructions in this Guide and follow all information regarding transport,
storage, installation and use of the Option module, including the
specified environmental limitations.
Please read the IMPORTANT SAFETY INFORMATION below, and all
Warning and Caution boxes elsewhere.
CAUTION
Store the Option in its box until
required. It should be stored in a
clean and dry environment.
Temperature range –40oC to
+60oC.
WARNING
The ACS250 and the Options
should be installed only by
qualified electrical persons and in
accordance with local and
national regulations and codes of
practice.
Electric shock hazard!
Disconnect and ISOLATE the
drive before attempting any work
on it. High voltages are present at
the terminals and within the drive
for up to 10 minutes after
disconnection of the electrical
supply.
Where the electrical supply to the
drive is through a plug and socket
connector, do not disconnect until
10 minutes have elapsed after
turning off the supply.

EXAMPLE OF USING THE MODBUS NETWORK TERMINATOR
SPLITTER RJ45.
Modbus Network Terminator
Splitter RJ45
The Modbus Network Terminator Splitter allows
easy installation of a Termination resistor on
RS-485 communication networks.
Termination resistors are used to reduce signal reflections
on the communications network, most often experienced
on long cable runs and high baud rates.
The decision to use termination resistors is dependent on
the individual application; in general they are only added if
needed.
If termination resistors are required then they should be
installed at both ends of a network segment. The resistor
value should ideally match the cable characteristic
impedance, with a typical value being 120Ω.
For further details please refer to the ACS250 User manual.
Note:
This Option is suitable for use on all ACS250 Drives.
