･Safety Precautions
(1) Watanabe Electric Industry Co., Ltd assumes no responsibility for any
special damage, indirect loss or passive loss caused by this device.
(2) This device has been developed, designed and manufactured on the
premise that it is to be used as general machinery. Please ensure
attention is paid to safety by adopting such means as a fail-safe design
and a redundancy design, and by conducting regular checks on the
device, particularly when it is being used for purposes such as the
following, where safety is of utmost importance.
• Safety devices used for personal protection
• Rail, aviation and vehicular equipment
• Medical equipment
• Incineration systems, nuclear systems
• Other purposes conforming to the conditions above which require high
levels of safety
(3) Please do not use this device for applications which directly affect
human lives.
(4) When this device is to be used in conjunction with other products,
please check for conformance with specifications, provisions of law and
regulations before use to ensure compatibility.
(5) As the operating life of the comparative output relays varies greatly
depending on switching capacity and conditions, please ensure the
relays are used within their rated load and electrical life.
deteriorated relays could result in insulation failure between circuits or
burnout of the relays themselves.
(6) This device requires more than 40 minutes warm up time from when
power is activated in order to operate within its degree of accuracy.
(7) Please do not wipe this device with alcohol, paint thinner, benzene,
acetone or other organic solvents. When wiping the device, please use
