The diagram below shows the balance’s connection to earth:
Place the platform balance and the display unit on the intended installation site in the
ex-area and connect it to earth.
CAUTION!
•
The assembly of the display unit, installation of the platform
balance and the connection to earth must be carried out within
a time frame that rules out the risk of developing an explosive
atmosphere.
•
Place the platform balance in a level, stable place as far away as possible from
heat sources and drafts.
•
Level the balance with the help of the adjustable feet and a spirit level.
•
Check, whether the adjustable feet stand on the balance base.
•
Ensure that the weight is evenly distributed among the feet.
•
Check once again that the installation site for the balance is level. Exact flatness
is established when the air bubble of the spirit level is in the centre of the spirit
level ring.
•
If further levelling of the platform balance is required, turn the adjustable feet of
the balance in order to adjust the height.
•
Check the earth contact springs between the platform balance and the weighing
pan. This ensures that the electrostatic charge is discharged from the weighing
pan.
