Precautions for CE Markings
Keyence confirms that the LS-7000 Series meets EC directive requirements. The LS-7000
Series bears CE markings. Keep the following conditions if the LS-7000 Series is used in
European countries.
■ EMC Directives
Keep the following condition so that the LS-7000 Series will satisfy EN61326-1
requirements.
• The power cable and I/O cable connected to the controller are both less than 30m in
length.
• Attach the OP-31973 Clamp-type Ferrite Core to the cable between the controller and
measuring head. The attaching position is as close as possible to the cable end on
the controller side, where the core must be snapped onto the cable to form a one-turn
loop.

■ Low-voltage Directives
When using the LS-S11 AC Power Supply Stand as a dedicated power supply to the LS-
7000 Series, keep the following conditions so that the LS-S11 will satisfy EN61010-1
requirements. The LS-S11 satisfies EN60825-1 (LED Class 1) requirements with no
conditions attached.
Environment Conditions
Installation category (Overvoltage category): II (see note 1)
Pollution degree: 2 (see note 2)
Operation and Installation Conditions
• The LS-S11 AC Power Stand is a dedicated power supply for the LS-7000 Series.
Never use the LS-S11 for other purposes.
• When using the LS-7000 Series in European countries, check that the AC power
supply cable satisfies EC directive requirements certified by an authorized third party.
Consult your Keyence representative for the AC power supply cable in detail.
• Before turning the LS-7000 Series on, connect the ground terminal of the AC power
supply cable to the protective ground terminal of the power supply.
• Be sure to use a time lag fuse rated 250 V, 3.15 A for the replaceable fuse of the LS-
S11.
Note 1:
Installation categories (overvoltage categories) include impulse overvoltage regu-
lations at transient overvoltage levels specified by EC directives.
Installation category II indicates a level where power is provided from fixed
installations, such as distribution panels.
Note 2:
The pollution degree refers to the level of solid, liquid, or gas contamination that
deteriorates the dielectric strength or surface resistance of the LS-7000 Series.
Pollution degree 2 indicates the normal indoor environment (free of non-con-
ductive contamination).
