NOTICE
The cable screen is connected to the load cell housing.
Make sure to use the PR 6024/68S cable junction box (see Chapter 11.2.4 .
The cable junction box is still required even if only 1 load cell is being connected.
NOTICE
The digital load cell will be destroyed if connected incorrectly.
Ensure that the load cells are connected in accordance with the connection plans in
Chapter 6.6 .
See also the safety instructions in Chapter 12.1 .
6.2.1 Load cell cable
The load cell cables are inseparably connected to the load cells in the factory.
The digital load cell cable may be shortened.
The special sheathing material ensures extremely long service life even under diicult
operating conditions.
However, despite the robust nature of the materials used, the cable should be protected
from excessive chemical and mechanical stresses. Preventing water from penetrating the
end of the cable is also important "life insurance" for the system.
6.2.2 Lightning protection
To retain the functionality of the load cells even in the case of lightning strikes near the
scale, the cable junction box PR 6024/68S must be used.
NOTICE
Additional lightning protection elements in the measuring circuit compromise the
high measuring accuracy of the load cells or the lightning protection.
Always carry out the installation exclusively according to the instructions in order not to
void any warranty claims.
In particular, the entire installation, including the power supply, must be suiciently
protected against lightning! Simply connecting the protective grounding conductor
is not enough!
6.3 Cable junction boxes
The cable junction box PR 6024/68S (see Chapter 11.2.4 ) must be used to connect the
load cells. These boxes have extremely high-quality screw terminals with high contact
security and long-term stability along with a special conduit as well as integrated
elements for transient overvoltage protection.
The special valve with a GoreTech semi-permeable membrane ensures permanent
pressure compensation during luctuating temperatures and weather conditions, and
efectively prevents water from penetrating.
