NOTICE

Welding or lightning strike current flowing through the cell can damage it.

All electrical welding on the weighing system must be finished before mounting the load
cells.

When installing the load cell, immediately bypass the load cell with a flexible copper
strap (included in the load cell equipment).

During any additional electrical welding work near the load cell:

-

Disconnect the load cell cables.

-

Bypass the load cell using the flexible copper strap.

-

Make sure that the grounding clamp of the welding set is fitted as closely as possible
to the welding joint.
