All components must be disposed of in a manner that does not harm the environment
and in line with legal requirements.
8.7 Assembly and disassembly
Before assembly, check that the ambient temperature range and the protection class on
the rating plate meet the requirements for the assembly area.
The fastening bores used to install the enclosure are depicted in Figure 1. The eight M5
threads for the protective enclosure can be used to attach the protective enclosure to the
mounting plate. Alternatively, a mounting rail can be used to attach the enclosure to a
wall bracket. When assembling the enclosure, ensure that the screws are tightly fas-
tened: use a maximum torque of 3.5 Nm for the M5 fastening screw threads. Use locking
washers to prevent the fastening screws from becoming loose.
Note
It is advisable to attach the sun canopy to the protective enclosure if the device is going to be used
outdoors.
8.8 Installation
Installation work must only be carried out by specialist personnel
Installation work may only be performed by personnel who have been au-
thorized and trained to do so. All applicable national regulations in the country in
which the product is used must be observed (e.g. EN 60079-14). The manufac-
turer or personnel authorized by the manufacturer must assemble the cable
glands or the connectors for the enclosure and install the connection lines.
Hazard caused by live parts
Ensure that all supply lines are disconnected from the mains electricity supply
and that they cannot be switched on inadvertently.
Hazard caused by incorrect cable glands
Explosion protection is no longer guaranteed if incorrect cable glands are used.
Only use cable glands that are suitable for the required protection type and that
are specifically listed by the manufacturer as suitable for the enclosure you are
using. See the section “Permitted cable glands and connectors.”
Hazard caused by faulty cable anchorage
When using cable glands, explosion protection is no longer guaranteed if the ca-
ble anchorage is faulty. Install cables and lines securely. Observe the instructions
for cable feed-through.
Hazard caused by damaged threads
If a thread is damaged, there is no guarantee that the joint is flameproof. Remove
and replace the enclosure cover carefully. Any enclosure cover or enclosure with
damaged threads must be replaced immediately.
