6. Safety
For safety reasons, all work in pits must be
supervised by a person outside the pit.
Pits for submersible drainage and effluent pumps
may contain drainage or effluent with toxic and/or
disease-causing substances. Therefore, all persons
involved must wear appropriate personal protective
equipment and clothing, and all work on and near the
pump must be carried out under strict observance of
the hygiene regulations in force.
Carelessness during lifting or transportation may
cause injury to persons or damage to the pump.
6.1 Potentially explosive environments
Use explosion-proof pumps for applications in
potentially explosive environments.
This appliance can be used by children
aged from 8 years and above and persons
with reduced physical, sensory or mental
capabilities or lack of experience and
knowledge if they have been given
supervision or instruction concerning use
of the appliance in a safe way and
understand the hazards involved.
Children shall not play with the appliance.
Cleaning and user maintenance shall not
be made by children without supervision.
Pump installation in pits must be carried
out by specially trained persons.
Work in or near pits must be carried out
according to local regulations.
Persons must not enter the installation
area when the atmosphere is explosive.
DANGER
Electric shock
Death or serious personal injury
- It must be possible to lock the main
switch in position 0. Type and
requirements as specified in EN 60204-
1, 5.3.2.
DANGER
Electric shock
Death or serious personal injury
- Make sure there are at least 3 m free
cable above the maximum liquid level.
We recommend that you carry out all
maintenance and service work when the
pump is placed outside the pit.
DANGER
Crushing hazard
Death or serious personal injury
- Make sure that the lifting bracket is
tightened before attempting to lift the
pump. Tighten if necessary.
The pumps must under no circumstance
pump combustible or flammable liquids.
The explosion protection classification of
the pumps is CE Ex II 2 G, Ex d IIB T4. The
classification of the installation site must
be approved by the local fire-fighting
authorities in each individual case.
The letter X in the certificate number
indicates that the equipment is subject to
special conditions for safe use. The
conditions are mentioned in the certificate
and in these installation and operating
instructions.
Special conditions for safe use of
explosion-proof pumps:
1. Bolts used for replacement must be
class A2-70 or better according to EN/
ISO 3506-1.
2. The pump must not run dry. The level
of pumped liquid must be controlled by
two stop level switches connected to
the motor control circuit. The minimum
level depends on the installation type
and is specified in these installation
and operating instructions. The pumps
can be used in duty cycles S3, halfway
submerged, or S1, fully submerged.
3. Make sure the permanently attached
cable is suitably mechanically
protected and terminated in a suitable
terminal board placed outside the
potentially explosive area. The supply
cable plug may only be disconnected
by the manufacturer or his
representative.
4. The thermal protection in the stator
windings has a nominal cut-out
temperature of 150 °C guaranteeing
the disconnection of the power supply;
the resetting of the supply is manual.
5. The IP68 rating is limited to maximum
10 m submersion depth.
6. The ambient temperature range is
limited to -20 - +40 °C for ambient
temperature and 0-40 °C for liquids.
7. Contact the manufacturer regarding the
"d" protection type for pumps and for
information on the dimensions of the
flameproof joints.
