To prevent a EC207 unit malfunction due to excessive noise, isolate all EC207
input/output signal lines from all power wiring or power cables via a separate
wiring duct.
Be sure all cable connectors are securely attached to the EC207 unit.A loose
connection may cause incorrect input or output signals.
Be sure to ground the EC207 unit’s FG wire separately from other equipment
FG lines. Also, be sure to use a grounding resistance of 100. or less and a
2mm2or thicker wire, or your country’s applicable standard. Otherwise, electric
shock or malfunctions may result.
Be sure to use only the designated torque to tighten the EC207 unit’s terminal
block screws. If these screws are not tightened firmly, it may cause a
short-circuit, fire or incorrect unit operation.
Be sure that metal particles and wiring debris do not fall inside the EC207 unit.
They can cause a fire, malfunction or incorrect unit operation.
Be sure to read the EC207 unit’s manual carefully before performing program
changes, entering forced output, or using the RUN, STOP, or PAUSE
commands while the EC207 is operating. Mistakes made when usingthese
items can cause machine accidents or damage.
Warning
To prevent electrical shock or equipment damage, unplug the EC207 unit’s
power cord from the power supply prior to installing or wiring the EC207.
After completing any EC207 wiring work, be sure the terminal block’s
protective plastic cover is reattached. If this cover is not reattached, an
electrical shock could easily occur.
To prevent an electric shock be sure to disconnect your EC207 unit’s power
cord from the power supply before wiring the EC207.
Do not use voltage beyond the EC207 unit’s specified range. Doing so may
cause a fire or an electric shock.
The cables connected to the EC207 should be secured by cable clamps to
prevent weight or tension of the cables added to the connectors or terminals.
The EC207 unit’s wiring should be checked to confirm that both the operating
voltage and wiring terminal locations are correct. If either the voltage or the
wiring terminal location is incorrect, it can cause a fire or accident.
Do not connect or disconnect Host and EC207 unit communication cables
while the EC207 is turned ON.
Do not replace the EC207 unit’s battery yourself. The EC207 uses a lithium
battery for backing up its internal clock data and the battery may explode if it is
replaced incorrectly. When replacement is required, please contact your local
EC207 distributor.
