SL-V-M-NO0-E
• The installation of muting lamp may be required by the laws, rules, regulations, and stan-
dards in the country or region in which the SL-V is used if you apply the muting function. It
depends on the machine application and/or the result of your risk assessment. If it is neces-
sary for you to provide the muting lamp, you must fulfill the requirements because you are
fully responsible for installation of muting lamp.
• When the reduced resolution function is applied, the detection capability varies according to
your configuration. Make sure to accurately calculate the safety distance according to the
detection capability, and install the SL-V at a distance greater than or equal to the minimum
safety distance away from the hazardous zone or hazard. The installation of additional safety
measures, such as a safeguarding, may be required if the detection capability varies due to the
configuration of the reduced resolution function. On your own responsibility, you must perform
the risk assessment based on your configuration of the reduced resolution function in order to
reduce the risk.
• When the fixed blanking function is applied, a hazardous clearance that is not protected by
the SL-V may be generated between the obstacle and the SL-V. You must install an addi-
tional safety measure such as a safeguard for this clearance.
• The override is a function to allow a temporary manual suspension of the safety functions of
the SL-V. Therefore, additional safety measures are required for the whole machine system
on which the SL-V is installed in order to ensure safety while the override is activated.
• The override devices, the installation of those devices and the procedures to activate the
override must fulfill the conditions specified in this manual as well as the requirements of the
laws, rules, regulations and standards in the country or region in which the SL-V and those
devices are used. Failure to follow this warning may result in significant harm to the
machine operators, including serious injury or death.
• The override devices, which are used for activation of override, must be manual operating
device. When installing the devices to activate the override, those devices must be installed
so that the whole hazardous zone can be checked by the responsible personnel and so that
it is not possible for machine operators to operate those devices in the hazardous zone.
• The installation of the indication for override may be required by the laws, rules, regulations,
and standards in the country or region in which the SL-V is used if you apply the override
function. It depends on the machine application and/or the result of your risk assessment. If
it is necessary for you to provide the indication for override, you must fulfill the requirements
because you are fully responsible for installation of the indication for override.
• The customer is fully responsible for complying with the requirements for the muting and/or
override. Those who use muting and/or override must fulfill all of the requirements related to
muting and/or override. KEYENCE accepts NO responsibility or NO liability for any damage
or any injury due to the unauthorized installation, usage or maintenance, which are not
specified in this user’s manual, and/or due to noncompliance with the laws, rules, regula-
tions and standards in the country or region in which the SL-V is used.
• Securely tighten mounting brackets and cable connectors used for the installation of the SL-
V in accordance with the torque values specified in this user’s manual.

Circuit design and wiring
• Always turn off the power to the SL-V when performing electrical wiring.
• You must fulfill the electrical standards and regulations in the country or region in which the
SL-V is being used when you perform the electrical wiring.
• To avoid the risk of electric shock, do not connect any of the SL-V inputs to DC power
sources outside of the range of 24 V DC + 10% or to any AC power source.
• To avoid the risk of electric shock, be sure that the hazardous voltage is isolated from all
wiring of the SL-V with reinforced insulation or double insulation.
