CAUTION

Install the product in accordance with the required installation conditions.

Do not disassemble, modify, or alter the product.

Contact Riken Keiki to request readjustment or parts replacement including calibration.

Use cable lugs for grounding wire and bonding conductor connections. Make sure the bonding
conductors are not loose or twisted.

Do not open the cover in locations where explosive gas may be present.

The maximum pressure inside the gas channels and sensor is 10.13 kPa (gauge pressure).

Be sure to connect the grounding terminal before turning on the power to the product.

Make sure the grounding is Class D equivalent (grounding resistance less than 100 Ω).

Use crimped terminals to connect the grounding wire to the grounding terminal inside the unit. Use a
cable with a cross section area of at least 4 mm
2 to connect to the external grounding terminal.

Use approved cable glands when installing.

If the product is installed in a location where the ambient temperature exceeds 65 °C, use cables
designed for use at temperatures at least 5 °C above the maximum ambient temperature.

Do not subject the window in the cover to strong forces or impact. Doing so may result in damage and
impaired explosion-proof performance. (The low risk of mechanical hazards has been confirmed in
testing [2 joules].)

Do not use more than one adapter per connector.
CAUTION
With suction type

Use with a flow rate of at least 0.4 L/min and not exceeding 1.5 L/min.
