on flange of lid & base before closing.
Bolt the lid of enclosure and tighten the bolts using appropriate size of Allen keys. No
bolts should be missing or loose.
Lid bolts are of SS A2.70 grade. In case of replacement, replace by same size of same or
higher strength.
Danger due to not approved cable glands & accessories!
Only certified cable glands & accessories of required Ex protection shall be
used.
Each entry shall have no more than one thread adopter. A blanking element
shall not be used with a thread adopter.
In case of non-compliance explosion protection can no longer be guaranteed.
Danger due to open holes or unused cable entries on the enclosure!
If holes or unused cable entry is left open, explosion protection can no longer
be guaranteed.
Close open holes using stopping plugs approved for required type of
protection.

6.0 Commissioning
Check the device before putting it into service!
To ensure proper operation the equipment must be checked prior to putting it in
service.
If the enclosure is connected incorrectly, explosion protection is no longer
guaranteed!
The device must be operated only with completely closed enclosures.
Before commissioning ensure that:
No components are damaged.
The equipment has been installed according to regulations.
There are no foreign bodies inside the device.
The specified tightening torques has been observed.
7.0 Inspection, Maintenance, Repair and Overhaul
7.1 Inspection and Maintenance:
Consult the relevant national regulations (e.g. IEC/EN 60079-17) to determine the type
and extent of inspections.
Plan the intervals such that any expected defects are detected promptly.
Risk of Electric Shock!
Before opening the device, disconnect it from power supply and wait for some
time to allow internal components to cool down.
7.2 Repair and Overhaul
Damaged enclosure cannot be repaired at site. Only control accessories, electrical components,
cable glands &accessories can be changed. Please follow IEC/EN 60079-19 for repair of damaged
enclosure. Only certified control accessories of Rose must be used.
8.0 Specific conditions ofuse:
For enclosures provided with a powder coating, liquid painting or
provided with a non-metallic nameplate and/or tagplate and intended
for use in Group III applications, the user shall minimize the risk from
electrostatic discharge by suitable selection and installation.
The flanged flame path of the cover differs from the values stated in EN
60079-1. Contact the manufacturer for information on the dimensions of
the flameproof joints.
The M6, M8, M10 and M12 fasteners are of grade A2-70 with a yield
stress of at least 450 MPa and shall be applied with a minimum torque
value of 11 Nm (M6), 28 Nm (M8), 58 Nm (M10) and 95 Nm (M12).
LED Indicating lamps, if assembled, are suitable for low risk of
mechanical danger i.e., 2 Joules.
Control Accessories i.e., indicating lamps, Push button and Rotary
actuators, if assembled, may pose risk of electrostatic discharge hence
clean with damp cloth only.
