The connection between this product and the intrinsically safe end of the safety barrier should be a shielded cable with a cross-section> 0.5mm2, and the shielding layer must be grounded. The distributed capacitance and inductance of the cable must be less than the safe value. The safety barrier is installed in a safe place, and its installation and use must comply with the safety barrier instruction manual. The user is not allowed to change the electrical components in the product at will.
