Important Note
Where the risk assessment identifies that inadvertent operation of the E-Stop button may occur during use or breakage and loss of the button function is foreseen, it may be preferable to specify the protection shroud version. When required by local regulations, please affix the supplied yellow emergency stop sticker.
