CAUTION

If the product is used outside of specified limits, this voids the product
certification, and our company is not responsible for any incurred warranty
expense.

Do not open this product, except for the terminal compartment as listed in
this document, under any circumstances.

The detector is not field-repairable. Any attempt to modify or repair the
internal circuits or change their settings, as this will impair the system’s
performance and void the product warranty.

Opening the attachment screws to dismantle the front part of the detector
from remaining parts is restricted and voids the product warranty.

3 Special conditions for safe use

• Lids securing fasteners shall be property class A4 with a yield stress of

344N/mm2.

• Units may be painted or fitted with optional accessories, some of which

are made of non-metallic material or have a non-metallic coating which
could potentially generate an ignition-capable level of electrostatic
charge under certain extreme conditions (such as high pressure steam)
which might cause a build-up of electrostatic charges on the non­conducting surfaces. Additionally, cleaning of the equipment should
only be done with a damp cloth.

• Under rated conditions, the cable entries reach a temperature exceeding

158 °F (70 °C), and the branching point exceeds a temperature of 176 °F
(80 °C); this shall be considered when installing cable glands, and only
cables that have temperature ratings suitable for the application shall be
used.

• Flameproof joints are not intended to be repaired.

• The SharpEye 40/40 Series Flame Detectors can be fitted with an

unmolded (non-encapsulated) end of line (EOL) resistor. Such a resistor
can only be fitted into the flameproof "Ex d" compartment as indicated in
the instructions. The EOL resistor shall be rated at 1.56 kΩ, 1 W
minimum.

To reduce the risk of ignition of a flammable or explosive atmosphere,
strictly adhere to the following statements:

WARNING

Do not open when energized.
Do not open when an explosive atmosphere is present.
Temperature at branching point may exceed 212 °F (100 °C).

CAUTION

Potential electrostatic charging hazard

See instructions.
