The T20 liteServer
®
series may only be opened due to functional aspects and only if it is
explicitly allowed in the respective user manual. In all other cases, the explosion-proof
housing may only be opened and closed by authorized staff of SAMCON Prozessleittech-
nik GmbH. Any damages, irregularities, or changes which, through the transparent open-
ing, are visible inside the liteServer
®
, for example, loosened or not tightened components,
discolouration, or liquid inclusions (not to be confused with condensed water!), have to be
checked by the manufacturer, SAMCON Prozessleittechnik GmbH.
Please absolutely observe the following points:
Before opening the housing of the T20-VAx.x.x.x type, it may be necessary to remove the
weather protection roof or other external accessories.
- Remove or loosen the bolted connections of the illuminator housing flange and
body.
- Use only appropriate tools and pay attention to the respective spring rings (DIN
127A).
- Caution: Avoid any contact of the screw thread with skin and/or clothes! The screw
threads are covered with
LOCTITE® 243™ (chemical basis is dimethacrylate ester).
This is to prevent the bolted connection from unintentional loosening because of
impacts and vibrations and for sealing purposes.
