manual; otherwise contact Emerson Retail
Solutions for the correct manual.
WARNING! An isolated transformer for the
XM678D power supply must be used. Do not
share power with any other devices.
CAUTION!
• This manual is part of the product and should
be kept near the device for easy and quick
reference.

• The device should not be used for purposes different
from those described in this manual. It cannot be used
as a safety device.

• Check the application limits before proceeding.
SAFETY PRECAUTIONS AND

WARNINGS!
• Check that the supply voltage is correct
before connecting the device.
• Do not expose to water or moisture: use the
controller only within the operating limits and avoid
sudden temperature changes with high atmospheric
humidity to prevent condensation from forming.
• Warning! Disconnect all electrical connections
before performing any kind of maintenance.
• Fit the probe where it is not accessible by the end
user. The device must not be opened.
• In case of failure or faulty operation, send the
device back to the distributor or to Emerson Retail
Solutions (see address) with a detailed description of
the fault.
• Verify the maximum current that can be applied to
each relay (see Section 20, Technical Data).
• Ensure that the wires for probes, loads, and the
power supply are separated and far enough from each
other without crossing or intertwining.
• In case of applications in industrial environments,
the use of main filters (our mod. FT1) in parallel with
inductive loads could be useful.
