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
