5.2 Installation conditions
Built in components
The T Class is dependent on power dissipation of components, wiring and Max ambient
temperature. Refer Technical data.
Only replacement of components built inside the enclosure is permitted. Any addition or
alternation without consultation to ROSE is not permitted and may lead to ignition risk.
Replacement of Display window is not possible.
5.3 Mounting and operating position
Mounting the enclosure
 Mount the enclosure by using four screws. Refer dimensional drawing for mounting holes
& mounting dimension.
 Tighten the mounting screws properly.
Opening the enclosure
 The enclosure lid is bolted. Use Allen key of appropriate size to open lid bolts.
Closing the enclosure
 These enclosures are with/ without O ring in base. In case O ring is damaged, please
replace with supplies from ROSE and mount properly in groove.
 In case O Ring is not provided, ingress protection is ensured by application of silicone
grease Anabond 662 or equivalent (e.g. Fuchs Renolit Unitemp 2).
 To prevent corrosion of flange joint it is coated with silicone grease Anabond 662 or
equivalent (e.g. Fuchs Renolit Unitemp 2).
 Apply a coat of silicone grease Anabond 662 or equivalent (e.g. Fuchs Renolit Unitemp 2)
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.

IM.IJB.X.12.2018 IECEx/ATEX Page 10
5.4 Electrical Connection
Internal wiring
Incorrect wiring inside enclosure!
 Strictly adhere to wire size and length for which heat loss dissipation are
taken into account for permissible wattage for a given T Class. In case of
non-compliance explosion protection can no longer be guaranteed.
 Strictly adhere to the creepage and clearance required.
 Use only insulated wires of suitable voltage grade.
 Mounting rails or components must be loosened and fastened properly.
External Wiring
Danger due to improper cables!
 The cables must comply with IEC/EN 60079-14 and relevant regulation and
must have the required cross section.
 Strictly adhere to cable size and length for which heat loss dissipation are
taken into account for permissible wattage for a given T Class and ambient
temperature.
 In case of non-compliance explosion protection can no longer be
guaranteed.
Danger due to improper cable glands!
 The cable glands shall be appropriate to cable type and size and with
suitable approval as per IEC/EN 60079-14.
 Entry threads have been marked on enclosure by sticker, please use cable
gland of appropriate size and type.
 In case of non-compliance explosion protection can no longer be
guaranteed.
Protective Earth conductor connection
Always connect the protective earth (PE) conductor!
 The device is equipped with one internal and two external protective
conductor connection arrangements with SS Screw, 1 No. tooth (Anti-
rotational) washer and 2 No. plain washers.
 Use ring type lug of suitable material and size to be affixed between 2 plain
washers.
 The PE conductor size shall be as under:
Cross sectional area of
phase Conductor S mm2
Minimum cross sectional area of the
corresponding PE conductor in mm2
S ≤ 16
S with min of 4mm2
16 < S ≤ 35
16
S>35
0.5 S

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.
8.0 Specific conditions of use:

The ambient temperature range depends on the model (with or without
glass window), the pressure applied during the routine overpressure test
and on the glass thickness. See instruction manual point no 4.
 For enclosures provided with a powder coating or liquid painting and
intended for use in Group III applications, the user shall minimize the risk
from electrostatic discharge by suitable selection and installation.
 The maximum number of apertures, their maximum sizes and their
positions are specified in the instruction manual point no 4.
 The flanged flame path is more than required by IEC 60079-1. Contact
ROSE for information on the dimensions of the flameproof joint.

Refer to associated certificates of Ex components/ equipment used in
assembly.
