For personal and system safety, all tags attached to the transmitter housing must remain visible. Clean or replace them as necessary.

2.2Transmitters approved for ATEX Zone 1

WARNING

Explosion hazard

The circuit board compartment is rated EEx d (flameproof), and should remain closed at all times after the flowmeter has been installed.

To avoid risk of explosion in an explosive atmosphere:

•Read label that points to compartment cover before accessing circuit board compartment. Figure 2-2 shows the location of the labels on the transmitter housing.

•Shut off power, and wait at least 2 minutes before removing EEx d (circuit board) compartment cover. Figure 2-2 also identifies the EEx e (field wiring), EEx i (sensor wiring), and EEx d (circuit board) compartments.

If the transmitter carries an ATEX Zone 1 approval, wiring compartments are labeled as shown in Figure 2-2.

•The sensor wiring compartment is rated EEx i (intrinsically safe), and may be opened at any time. See Label 1 in Figure 2-2.

•The field wiring compartment is rated EEx e (increased safety), and should remain closed when power is on. See Label 2 in Figure 2-2.

•The circuit board compartment is rated EEx d (flameproof), and should remain closed at all times after the transmitter has been installed. If the transmitter is approved by ATEX as flameproof, the compartment has a lockout device, shown in Figure 2-2. The lockout device must be loosened and rotated before the compartment cover can be unscrewed.
