External Forces; Inspection Prior To Commissioning, Maintenance And Re-Inspection; Electrical Equipment Inspections, Routine Inspection - Wilo Sinum MP M-2-50 Notice De Montage Et De Mise En Service

Mechanical hazards:
The fan-wheel casing on the pump protects
operators from personal injury from moving parts.
Before commissioning, check that it is fit for
purpose and fixed in place. Expansion automats
with protective casings are protected against dirt,
prevent unauthorised operation and minimise
noise emission.
Electrical hazards:
The protection class of electrically operated
components prevents personal injury by electro-
cution, which can be fatal. The protection class is
usually IP54 (5: Dust protected, protected against
ingress with a wire; 4: protected against splashing
water). The control unit cover, the cover of the
pump feed, the threaded cable glands and the
valve connector plugs must be inspected for ef-
fectiveness prior to commissioning. The installed
pressure and volume sensors are operated with
protective extra-low voltage.
Avoid welding work on additional equipment
which is electrically connected to the control
unit. Stray welding current or an improper earth

connection could lead to the danger of fire and
damage to parts of the unit (e.g. the control unit).

4.15. External forces

Avoid any additional forces ( e.g.: forces caused by
heat expansion, flow oscillations or dead weights
on the flow and return lines). These can lead to
damage / leaks in water-bearing pipework, loss of
stability of the appliance and furthermore to fail-
ure connected with substantial material damage
and personal injury.
4.16. Inspection prior to commissioning, maintenance
and re-inspection
They guarantee operational safety and its obser-
vance in line with applicable European regula-
tions, European and harmonised standards and
additional national regulations of the EU member
states for this field of application. The required
inspections must be arranged by the owner or
operator; an inspection and maintenance log
book for scheduling and traceability of measures
taken must be kept.
Internal inspection
5 / QP
[ §15 (10)] In the case of internal inspections
the visual inspection may be replaced by similar
procedures and in the case of strength tests the
static pressure test may be replaced by similar,
non-destructive procedures if said tests would
not otherwise be possible due to system design
or not significant due to the system mode of
operation.
4.17. Electrical equipment inspections, routine in-
spection
Without prejudice to the considerations of the in-
surer/Operator, it is recommended that the elec-
trical equipment of the Wilo-Sinum be inspected
and documented together with the heating/cool-
ing unit no less than every 18 months (see also
DIN EN 60204-1 2007).
