Operation - Mettler Toledo 3390 GageMount Manual Del Usario

Any oscillation or bumping of the scale in a horizontal plane must be prevented by, for example, the application of check rods.
Shock/Vibration, Acetal & PEI pads must be fully sandwiched between conductive steel plates with only the vertical perimeter surface
exposed.
WARNING
RISK OF EXPLOSION DUE TO
STATIC-ELECTRICITY DISCHARGE
• Connect equipotential bonding straps in accordance with national regulations & standards. In
particular, ensure that the scale frame (tank, hopper, etc.) is connected to all weigh module base
plates. Ensure that all connections between parts are conductive.
• Avoid static electricity build-up on non-conductive parts at all times. In particular, avoid any
highly efficient charge generating mechanisms to avoid propagating brush discharges. See also
cleaning instructions in section 5.
WARNING
DANGER OF EXPLOSION DUE TO
MECHANICALLY GENERATED SPARKS.
Impacts involving rust & light metals & their alloys can cause sparks.
• Do not use tools with rusty / corroded surfaces.
• Install all components in hazardous area in such a way that they are protected from impacts &
falling objects.
WARNING
DANGER OF EXPLOSION WITH
PAINTED SURFACES
The equipotential bonding only works with painted surfaces if a conductive connection exists.
• When possible, use only stainless, galva-nized or plated parts.
• Otherwise carry out suitable measures for the prevention of static-electricity discharge.

4 Operation

Observe the operating conditions and specifi-cations of the operating instructions for the various pieces of equipment making up the
system.
