STAR TU P
The "Start-up" chapter contains all the important instructions for
the operating personnel for starting up and operating the prod-
uct safely.
The following constraints must be adhered to and monitored:
- Type of installation
- Operating mode
- Minimum water coverage / max. submersion
If the machine has not been operated for an extended
period, these constraints must also be checked and
any discovered faults rectified.
This manual must always be kept either by the product or in a
place specially reserved for it, where it is accessible for the
entire operating personnel at all times.
In order to prevent damage or serious injury when starting up
the product, the following points must always be observed:
- The product may only be started up by qualified, trained per-
sons. The safety advice must be followed at all times.
- All persons working on or with the product must have
received, read and understood this operating and mainte-
nance manual.
- All safety devices and emergency cut-outs are connected
and have been checked to ensure that they work properly.
- Electrical and mechanical settings must be made by special-
ist staff.
- The product is suitable for use under the specified operating
conditions.
- The work area of the product is not a recreational area and is
to be kept free of people! No persons are allowed in the work
area during switching on and/or during operation.
- A second person must be present when working in shafts.
Adequate ventilation must be ensured if there is danger of
poisonous gases forming.
6.1
Electrical system
The product is connected and the power supply cables
installed in terms of the "Installation" chapter as well as the VDE
guidelines and the applicable national regulations.
The product is protected and grounded properly.
Pay attention to the direction of rotation. If the direction of rota-
tion is incorrect, the unit will not perform as specified and can
sustain damage.
All monitoring devices are connected and have been checked
to ensure that they work properly.
Beware of electrical current!
Electrical current can cause fatal injuries if
not handled correctly! All products with free
cable ends (i.e. without plugs) must be con-
nected by a qualified electrician.
6.2
Check the direction of rotation
The product is checked and adjusted in the factory to ensure
that the direction of rotation is incorrect. The connection must
be made according to the wiring code information.
Before submerging, the product must be checked to ensure
that the rotation direction is correct.
A test run should only be performed under general
operating conditions. Switching on a unit that has not
been submerged is strictly forbidden!
6.2.1 Checking the rotation direction
The rotation direction must be checked with a rotating field tes-
ter by a local electrician. For the correct rotation direction, a
clockwise rotating field must be available.
The product is not approved for operation with a coun-
ter-clockwise rotating field.
6.2.2 If the direction of rotation is not correct
When using Salmson switching devices
Salmson switching devices are designed so that the connected
products are driven in the right direction. If the rotation direc-
tion is wrong, 2 phases/leads of the mains supply to the switch-
ing device must be replaced.
With switching devices provided by the customer:
If the rotation direction is wrong, with direct start motors, 2
phases must be swapped. In the case of star-delta start-up
motors, the connections of two windings must be swapped
e.g. U1 with V1 and U2 with V2.
6.2.3 Checking the rotation direction on units with CEE
plug and integrated phase inverter
FIG. 4:
CEE PLUG WITH PHASE INVERTER
To function correctly, a clockwise rotating field must be avail-
able.
When the CEE plug is plugged in, the lamp must not light up. If
the lamp lights up, the direction of rotation is incorrect.
To correct the direction of rotation, you must push the phase
inverter into the plug with a suitable screwdriver and turn it
180°.
6.3
Adjusting the level-control device
For correct adjustment, please see the installation and opera-
tion manual for the level control device.
Please observe the information on the minimum water
coverage of the product!
6.4
Operation in explosion hazard areas
The operator is responsible for defining the explosion hazard
area. Only products with ex-approval may be used within an
explosion hazard area. Attached switching devices and plugs
must be checked for use in explosion hazard areas.
Products that are ex-approved are labeled on the type plate as
follows:
- Ex symbol:
or
APPROVED
- Ex-classification, e.g. Ex d IIB T4
