* This intrinsically safe product is designed for use in an industrial environment above ground, in zone 1 where an explosive atmosphere is likely to occur from time to time and in the presence of group IIC gases (eg acetylene). The surface temperature of the product will not exceed 135°C. Care must therefore be taken not to use this product in the presence of gases with an ignition temperature lower than 135°C.
