Caution
①
A dedicated Ground connection must be used. Grounding should be to a D-class ground (ground
resistance of 100Ω or less).
②
The cross sectional area of the grounding cable shall be 2mm
2
minimum.
The Grounding point should be as near as possible to the controller. Keep the grounding cable as
short as possible.
Dedicated grounding --- Good Shared grounding --- Not acceptable

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) 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
30 mm minimum
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.
