13 / 18 page G-165 D4NL Precautions !Caution Do not insert the Operation Key with the door open. The machine may operate and damage may result. !Caution Do not use metal connectors or conduits with this switch. Damage to the broken conduit hole may cause electric shock. !Caution Change the head direction after changing the release key to the UNLOCK position. Do not change the head direction with the cov- er removed. Failure to observe these points may result in Switch malfunction or damage. Holding Force • Do not apply a force exceeding the specified holding force. Doing so may break the Switch and the machine may continue to operate. • Either install another locking component (e.g., a stop) in addition to the Switch, or use a warning sticker or an indicator showing the lock status so that a force exceeding the specified holding force is not applied. Safety Precautions • The Switch contacts can be used for either standard loads or microloads. Once a contact has been used to switch a standard load, however, it cannot be used for a load of a smaller capacity. Doing so may result in roughening of the contact surface and con- tact reliability may be lost. • Turn OFF the power before disassembling the Switch or touching any internal parts. Not doing so may result in electric shock. • Mount the Operation Key in a location where it will not come in con- tact with users when the door is opened or closed. Otherwise, injury may result. • Do not impose excessive force on the Operation Key when it is inserted into the Switch or drop the Switch with the Operation Key inserted. Otherwise, the Operation Key may be deformed or the Switch may be broken. • Observe the specified insertion radius for the Operation Key and insert it in a direction perpendicular to the key hole. • Do not use the Switch in starting circuits. (Use for safety confirma- tion signals.) • When using the Switch in emergency-stop circuits or other safety circuits that have a direct impact on human lives, operate the NC contacts that have a direct opening mechanism in direct opening mode. For safety purposes, prevent easy removal by, for example, mounting the Switch and Operation Key with one-way screws or attaching a protective cover and warning label. • In order to prevent short-circuit damage to the Switch, connect a fuse to the Switch in series. Use a fuse with a breaking current of 1.5 to 2 times the rated current. To conform to EN ratings, use a IEC269-compliant 10-A fuse type gI or gG. • Turn the power OFF when wiring. After wiring is completed, be sure to mount the cover before use. • In order to prevent burning due to overvoltage, insert a protective fuse in the solenoid circuits. • Do not use the Switch where explosive gas, flammable gas, or any other dangerous gas may be present. • Ensure that the load current does not exceed the rated current. • Be sure to wire the terminals correctly. • Be sure to evaluate the Switch under actual operating conditions after installation. • Do not drop the package or the product. Do not disassemble inter- nal parts. Release Key • The release key is used to unlock the Switch in case of emergency or if the power supply to the Switch stops. • If the release key setting is changed from LOCK to UNLOCK using an appropriate tool, the lock will be released and the safety door can be opened (mechanical lock models only). • After setting the release key to UNLOCK in order to, for example, change the head direction or perform maintenance, be sure to return it to LOCK setting before resuming operation. • When the Switch is used for the door of a machine room to ensure the safety of people performing adjustment work inside, if the release key is set to UNLOCK, the door will not be locked when the door is closed and no power will be supplied to the equipment. • Do not use the release key to start or stop machines. • The auxiliary lock must only be released by authorized personnel. • Do not impose a force exceeding 1 N·m on the release key screws. The release key may be damaged and may not operated properly. • To prevent the release key from being used by unauthorized per- sonnel, set it to LOCK and seal it with seal wax. Mounting • Do not use the Switch as a stopper. To prevent the door from com- ing into contact with the flange of the Operation Key, be sure to mount the Switch with a stopper as shown above. • When the Switch is used for a hinged door at a location near to the hinged side, where the Operation Key’s insertion radius is compar- atively small, if an attempt is made to open the door beyond the lock position, the force imposed will be much larger than for loca- tions far from the hinged side, and the lock may be damaged. Solenoid Lock Models The solenoid lock locks the door only when power is supplied to the solenoid. Therefore, the door will be unlocked if the power supply to the solenoid stops. Therefore, do not use solenoid lock models for machines that may be operating and dangerous even after the machine stops operating.
