Precautions

ENVIRONMENT

Do not use the E3C-L11M in the following places:

Places exposed to direct sunlight.

Places with high humidity that may cause condensation.

Places with corrosive gas.

Places with vibration or shock directly affecting the Sensor.

Do not use the E3C-L11M at a voltage that exceeds the rated

voltage range, or the E3C-L11M may be damaged.

Do not make mistakes in wiring, such as mistakes in polarity, or

the E3C-L11M may be damaged.

Do not short-circuit the load, or the E3C-L11M may be damaged.

Do not connect AC to the E3C-L11M, or the E3C-L11M may be
damaged.

CONNECTION AND MOUNTING

A maximum of 24 VDC±10% can be imposed on the

E3C-L11M. Check that the voltage of the power supply is
within the permissible range before turning on the E3C-L11M.

The power supply must be constructed so that the secondary
circuit is insulated with an isolating transformer.

Do not wire power lines or high-tension lines alongside the

lines of the E3C-L11M in the same conduit, otherwise the

E3C-L11M may be damaged or malfunction due to induction.
Be sure to wire the lines of the E3C-L11M separated from

power lines or high-tension lines or laid in an separate,
shielded conduit.

Do not strike the E3C-L11M with a hammer when mounting

the E3C-L11M, or the water-resistant properties of the

E3C-L11M will be lost.

CLEANING

Do not attempt to clean the E3C-L11M using paint thinner, or the
surface of the E3C-L11M will be damaged.

MOUNTING

The torque required to tighten each screw must be 7 kgf S cm
(0.71 N S m) maximum. Excessive tightening torque may damage

the Sensor Unit and Amplifier Unit.

POWER SUPPLY

If a standard switching power supply is connected to the

E3C-L11M, be sure to ground the FG (frame ground) and G

(ground) terminals of the switching power supply. The E3C-L11M

may malfunction due to switching noise that will be generated
from the switching power supply if these terminals are not

grounded.
