Do not remove the enclosure cover in explosive atmospheres when the circuit is alive (except IS models). Do not connect or disconnect the LCD module in explosive atmosphere when the circuit is alive. When the LCD is not installed, covers shall instead be fitted at the open connectors. Before you remove the unit or mount it, or before you connect or disconnect the wiring, turn off the power supply and the input signal for safety. Do not disconnect unless the area is known to be non-explosive. Take care not to generate mechanical spark when accessing to the instrument and peripheral devices in hazardous locations. Do not apply physical impact or friction on the B6U-B enclosure. Whenever you need to measure voltage across the terminals or apply a simulated input signal to the terminals, make sure that there is no danger of explosion in the atmosphere. Before connecting a HART communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe field wiring practices. Verify the certification of the product described on the specification label on the product. Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications. Verify that the environmental temperature is within the temperature class required for the area. Failure to follow these installation guidelines could result in death or serious injury: Make sure only qualified personnel perform the installation. The instrument modification or parts replacement by other than authorized representative of M-System Co., Ltd. is prohibited and will void the approval of Factory Mutual Research Corporation. The FM approval of model B6U-B is applied to the combination of the outdoor enclosure and the transmitter. The transmitter must not be separated or replaced.
