level signal leads to a new hazard potential (e.g. through heat-up of
bearing points on the machine in the area of ignition temperature). If this
cannot be ascertained, provide a low-level signal or suitable organisational
measures for monitoring of the bearing point temperature.
Avoid dust accumulation and remove dust immediately. Dust
accumulations have a thermally insulating effect and, if whirled up,
generate the formation of a potentially explosive atmosphere.
The pump should be integrated into the operator's lightning protection
concept.
All parts are to be checked regularly for corrosion. Replace the affected
parts.
Terminal boxes must be firmly closed and the cable breakthroughs
correctly sealed.
Additional electrical monitoring devices must be firmly connected and
correctly adjusted.
Protect the motor with a motor circuit breaker against inadmissible heating
up.
When reaching their nominal life, the motor bearings have to be replaced
or inspected to ensure their suitability for further utilisation.

All relevant persons (e.g., operating personnel, supervisors) must be
informed of the respective activity prior to starting any work. Observe the
precautionary operational measures and work instructions.
If protective and safety equipment has to be dismantled, it must be
reassembled immediately after finishing the work, and then checked for
correct function.
Ensure through suitable measures that movable or detached parts are
immobilized during the work and that no limbs can be caught in between
by inadvertent movements.
Carry out transport using only suitable hoisting equipment.
All the parts to be mounted onto the shaft end of the motor have to be
dynamically balanced according to the balancing system of the motor. With
a direct coupling, ensure that the parts align precisely (observe the
manufacturer's guidelines).
Assemble the product only outside of the operating range of moving parts,
at an adequate distance from sources of heat or cold.
Dry wet, slippery surfaces.
Cover hot or cold surfaces accordingly.
Prior to performing work, de-energize and depressurize the pump and
secure it against unauthorized switch-on. Work on electrical components
must be carried out by electrical specialists only. Observe any waiting
periods for discharging, if necessary.
Carry out electrical connections only according to the information in the
valid wiring diagram and taking the relevant regulations and the local
connection conditions into account.
Do not touch cables or electrical components with wet or damp hands.
Maintenance and repair work can be subject to restrictions in low or high
temperatures (e.g. changed flow properties of the lubricant). Therefore,
where possible, try to carry out maintenance and repair work at room
temperature.
