5.4 Drive
On selecting the motor size care has to be taken, that
the requirements acc. to ISO 5199 are fulfilled. Note
the Operating Instructions of the motor
manufacturer.
On application in zone 1 and 2 a motor with
valid Atex-certification must be used.
5.5 Electric Connection
Electrical connection work may only be carried
out by an authorised professional. The rules
and regulations valid for electrical technology,
especially those concerned with safety meas-
ures, must be observed. The regulations of the
national power supply companies operating in
that area must also be observed.
Before starting work, check that the information on the
motor name plate is the same as the local mains net-
work. The power supply cable of the coupled drive
motor must be connected up in accordance with the
wiring diagram produced by the motor manufacturer.
A protective motor switch must be provided.
In areas endangered to explosion IEC 60079-
14 must additionally be noticed for the electric
installation.
Care must be taken that the base frame (2x
M10-thread available for earthing screws) is
earthed by means of corresponding measures.
The direction of rotation must only be checked
when the pump is full. Dry running will cause
damage to the pump.
5.6 Final Control
Check alignment of coupling acc. to chapter 5.3.1
again. It must be possible to turn the unit easily by
hand at the coupling.
6. Start-up, Operation, Shut down
The plant may only be started up by people
who are familiar with the local safety regula-
tions and with these Operating Instructions
(especially with the safety regulations and
safety instructions given here).
6.1 Initial start-up
Before starting up the pump, check, if the following
points were controlled and carried out:
ƒ If pump is oil lubricated, first open oil drain (GD)
and drain off any liquid that may have collected
(e.g. condensation). Close oil drain (GD) and fill
oil as described in chapter 6.5.1.
ƒ For pumps with grease lubrication, no further lu-
brication is needed before initial start-up.
ƒ Pump and suction pipe must be filled completely
with liquid when starting up.
ƒ Turn pump unit once again by hand and check
that it moves smoothly and evenly.
ƒ Check that coupling guard is installed and that all
safety devices are operational.
ƒ Switch on any sealing, flushing or cooling devices
that are provided. See data sheet for quantity and
pressure.
ƒ Open valve in suction /intake pipe.
ƒ Set discharge side valve to approx. 25% of rated
flow quantity. With pumps with a discharge branch
rated width less than 200, the valve can remain
closed when starting up.
ƒ Secure, that unit is electrically connected acc. to
all regulations and with all safety devices.
ƒ Check direction of rotation by switching on and off
briefly. It must be the same as the directional ar-
row on the bearing frame.
6.2 Switch on drive
ƒ Immediately (max. 10 seconds on 50 Hz resp.
max. 7 seconds on 60 Hz currency feed) after
reaching normal operating speed open discharge
valve adjust the required operating point. The
pumping data shown at the type plate resp. in the
data sheet and / or the order confirmation must be
met. Every change is only permitted after talking
with the manufacturer!
Operation with closed valve in the suction and /
or discharge piping is not permitted.
On starting-up without back-pressure, the back-
pressure must be produced through throttling at
the discharge side. After reaching full back-
pressure open valve
