Caution
The earthling should be the dedicated grounding point. It should be a functional ground with less
than 100 Ω resistance.
The cross section of the grounding wire should be greater than 2mm
2
.
The ground point should be near this controller to make the wire length shorter.

Mounting location
Design the size of the control panel and the installation so that the temperature surrounding the controller is
55
o
C or less (Note 1). Mount the controller vertically on the wall with 30 mm minimum space on the top and
bottom of the controller as shown below.
Allow 60 mm minimum space between the front of the controller and the door (lid) so that the connectors
can be connected and disconnected.
Leave enough space between the controllers so that the operating temperatures of the controllers remain
within the specification range.
Avoid mounting the controller near a vibration source, such as a large electromagnetic contactor or circuit
breaker on the same panel.
Note 1) For the LEY40 and LEYG40 series, if the vertical transfer load is greater than the weight listed below,
the controller must be used at an ambient temperature of 40
o
C or less.
LEY40#EA: 9 kg, LEY40#EB:19 kg, LEY40#EC:38 kg
LEYG40#EA:7 kg, LEYG40#EB:17 kg, LEYG40#EC:36 kg
Caution
If the mounting surface for the controller is not flat or is uneven, excessive stress may be applied to the
enclosure, which can cause failure. Be sure to mount on a flat surface.
