Safety Precautions
WARNING
To prevent electrical shock, this device must be installed in a location that is only accessible
to people with appropriate knowledge about electrical safety. Install this device inside a
control panel that cannot be opened without the use of a key or tool.
Do not use this device in an environment with conductive contamination, or with dry
non-conductive contamination which can become conductive due to condensation, etc.
Otherwise, problems such as tracking phenomena may damage parts, resulting in fire.
Be sure to use the fuse described in the specifications for the power wiring of this device.
Otherwise, tracking phenomena or parts failure due to other factors may cause fire.
Be sure to check that the device has been correctly wired before turning on the power.
Incorrect wiring of this device may cause device failure and also lead to a dangerous accident.
Before removing, mounting, or wiring this device, be sure to turn off the power to this device
and all connected devices. After wiring this device, attach the separately sold terminal cover
(model No. 84515888-001). Otherwise, there is a danger of electric shock.
Do not touch live parts such as the power terminals. There is a danger of electric shock.
Do not disassemble this device. There is a danger of electric shock or device failure.
CAUTION
Use this device within the operating ranges given in the specifications (for temperature,
humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.). Otherwise, there
is a danger of fire or device failure.
Do not block the ventilation holes. There is a danger of fire or device failure.
Wire this device correctly in compliance with applicable standards, and use the power source
and installation methods specified in this user’s manual. Otherwise, there is a danger of fire,
electric shock, or device failure.
Do not allow wire clippings, metal shavings, water, etc., to enter the case of this device. There
is a danger of fire or device failure.
Firmly tighten the terminal screws to the torque listed in the specifications. Insufficient
tightening may result in fire or electric shock.
Do not use unused terminals as relay terminals. There is a danger of fire, electric shock, or
device failure.
Use the relays within the recommended service life. Otherwise, there is a danger of fire or
device failure.
Use an appropriate overcurrent protection device (fuse, circuit breaker, etc.) with a sufficient
breaking capacity for lines to which the relays of this device are connected to protect the
circuits. Otherwise, there is a danger of fire or device failure.
