Special Conditions for Safe Use (X) / Schedule of Limitations:
• The NTMOS Hydrogen Sulfide Toxic Gas Detector shall be connected directly to a junction box or instrument
suitable for the area of installation to provide protection for the flying leads.
• The NTMOS Hydrogen Sulfide Toxic Gas Detector, when the optional sinter guard is not fitted, meets the impact
test requirements according to the low level risk of mechanical danger. Therefore, when the optional guard is not
fitted, the NTMOS Hydrogen Sulfide Toxic Gas Detector must be located and installed such that the risk of impact
is reduced.
• In order to maintain IP66/IP67 Ingress Protection rating, the detector must be mounted vertically at a maximum
height of 18 inches from surfaces below.
