Install all protective covers and safety ground leads after installation. Failure to install covers
and ground leads could result in serious injury or death.
WARNING!
ELECTRIC SHOCK
To meet the safety requirements of IEC 1010 (EC requirement) and ensure safe operation of this
equipment, connection to the main electrical power supply must be made through a circuit
breaker (min 10 A) which will disconnect all current-carrying conductors during a fault
situation. This circuit breaker should also include a mechanically operated isolating switch. If it
does not, locate another external means of disconnecting the power supply close by. Circuit
breakers or switches must comply with a recognized standard such as IEC 947.
WARNING!
EXPLOSION
To maintain explosion-proof protection of the OCX 8800 in hazardous areas, all cable entry
devices and blanking elements for unused apertures must be certified flameproof, suitable for
the conditions of use, and properly installed.
WARNING!
EXPLOSION
To maintain explosion-proof protection of the OCX88C in hazardous areas, the sensor housing
must not be mounted to any surface or flange that exceeds 195 °C (383 °F).
WARNING!
EXPLOSION
To maintain explosion-proof protection of the OCX88C in hazardous areas, the sample entering
the sensor housing must not exceed 195 °C (383 °F).
Note
To maintain proper earth grounding, ensure a positive connection exists between the sensor
housing, the electronics housing, and earth. The connecting ground wire must be 14 AWG
minimum. Refer to
Note
Line, voltage, signal, and relay wiring must be rated for at least 105 °C (221 °F).
