● Use the product in the environment that meets the "GENERAL SPECIFICATIONS" in the manual "Safety Guidelines" included in the CPU module or head module. Failure to do so may result in electric shock, fire,
malfunction, or damage to or deterioration of the product.
● Prevent foreign matter such as dust or wire chips from entering the
module. Such foreign matter can cause a fire, failure, or malfunction.
● Before handling modules, touch a grounded metal object to discharge
the static electricity from the human body. Not doing so may cause
failure or malfunctions of the module.
CAUTION
Mounting
b
● Modules must be mounted on a DIN rail.
● Connect an END cover on the last module on the right side.
● Do not drop the module or subject it to heavy impact.
● Do not open or modify a module. Doing so can cause a failure, mal-
function, injury or fire.
● Do not directly touch any conductive parts and electronic components
of the module.
● To interconnect modules, engage the respective connectors and
securely lock the module joint levers. Incorrect interconnection may
햲
cause malfunction, failure, or drop of the module.
CAUTION
Connecting the modules
The procedure for connecting modules is shown with an example of how to
connect the L02CPU to the power supply module L61P.
햲 To release the module joint
levers located at the top and
bottom of the L02CPU:
Slide the levers toward the
front side of the module.
햳 Insert the connector of the
CPU module into that of the
power supply so that they
are securely engaged.
햴 To lock the module joint
levers:
Slide the levers toward the
back side of the module.
Make sure that the modules
are securely connected.
햳 Hang the upper tabs of the
modules on a DIN rail, and
push the modules in position.
햴 Lock the DIN rail hooks to
the DIN rail to secure the
modules in the position.
Pull the hooks up until they
click. If the hooks are beyond
the reach, use a tool such as
a driver.
햵 Mount stoppers on the DIN rail beside the leftmost and rightmost module,
to avoid lateral sliding.
NOTE
Do not slide modules from the edge of the DIN rail when mounting. Doing so
may damage the metal part located on the back of the module.
Wiring
b
● Do not lay PROFIBUS cables close to the main circuit, high-voltage
power lines, or load lines.
Otherwise effects of noise or surge induction are likely to take place.
Keep a safe distance of more than 100 mm from the above when
wiring.
● When disconnecting the PROFIBUS cable, do not pull it by holding the
cable part.
Be sure to hold its connector which is plugged into the module. Pulling
the cable with it connected to the module may damage the module
and/or cable, or cause malfunctions due to poor contact of the cable.
Applicable Cable and Connector
To connect the ME1PB1-L to a PROFIBUS/DP network, use only the PROFIBUS
connector and shielded twisted pair PROFIBUS cable complying with
EN50170.
Wiring precautions
Keep the PROFIBUS cable away from I/O module cables as much as possible.

Bus Terminator
Each end of the PROFIBUS DP network must be terminated with a resistor.
Since the ME1PB1-L is not equipped with a built-in terminating resistor, use a
PROFIBUS connector with built-in bus terminator if the ME1PB1-L is situated at
the beginning or end of a network.
It is recommended to use a bus terminator with the following specifications:
