Cautions during Use
• Follow instructions in 'Cautions during Use'.
Otherwise, it may cause unexpected accidents.
• 10-30 VDCᜡ power supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.
• Use the product, after 0.8 sec of supplying power.
• Wire as short as possible and keep away from high voltage lines or power lines, to
prevent surge and inductive noise.
Do not use near the equipment which generates strong magnetic force or high
frequency noise (transceiver, etc.).
In case installing the product near the equipment which generates strong surge
(motor, welding machine, etc.), use diode or varistor to remove surge.
• If the surface is rubbed with a hard object, PTFE coating can be worn out.
• This unit may be used in the following environments.
- Indoors (UL Type 1 Enclosure)
- Altitude max. 2,000 m
- Pollution degree 3
- Installation category II
Cautions for Installation
• Install the unit correctly with the usage environment, location, and the designated
specifications.
• Do NOT impacts with a hard object or excessive bending of the wire lead-out. It may
cause damage the water resistance.
• Do NOT pull the Ø 5 mm cable with a tensile strength of 50 N or over.
It may result in fire due to the broken wire.
• When extending wire, use AWG 23 cable or over within 200 m.
