Precautions
■ Correct Use
Do not use the product in atmospheres or environments that exceed
product ratings.
Connections
• The XS3 and XS2 Sensor I/O Connectors cannot be connected to
each other.
• When using Sensors with Connectors or Limit Switches, use the
Sensor I/O Connectors specified in the catalog.
Connector Connection and Disconnection
• Before connecting or disconnecting Connectors, make sure that no
power is being supplied to the Connectors.
• When connecting or disconnecting Connectors, be sure to hold the
Connectors by hand. Do not disconnect the Connectors by pulling
the cable.
• Do not touch the engagement side of any Connector with wet
hands. If there is any water on the Connector or near the Connec-
tor, be sure to wipe off the water before connecting or disconnect-
ing the Connector, otherwise the Connector may short-circuit
internally or not ensure good insulation.
• Make sure that engagement side of any Connector is free of metal
dust or power.
• Do not use pliers to tighten mounting the thread bracket, otherwise
the thread bracket may be damaged. Be sure to tighten each thread
bracket by hand within a torque of 0.2 N·m. If the thread bracket is
not tightened securely, the Connector may not maintain its proper
degree of protection or the thread bracket may fall off due to vibra-
tion.

Degree of Protection
• Do not impose external force continuously on the joints of pin
blocks and covers, otherwise the Connectors may not keep its
proper degree of protection (i.e., IP67).
• Connectors are not fully watertight. Do not use them underwater.
• The Connectors are not oil-resistant. Do not use them where they
would be subject to oil.
• If Connectors are used in places with vibration or shock, secure the
engaged side of each Connector, otherwise the Connectors may be
disconnected or fail to maintain their proper degree of protection.
• Connectors are of resin mold construction. Do not impose exces-
sive force on them.
Storage
Do not store Connectors for long periods of time in the following loca-
tions
• Locations subject to dust or high humidity
• Locations subject to ammonia gas or sulfide gas
Installation
• Do not make any cable bends near the base of the Unit.
• Any bends made must have a minimum radius of 36 mm.
