.
It is important to be aware of the EUROPEAN
DIRECTIVE on potentially explosive areas where
compliance with IEC60079-14 is an additional
requirement for making electrical connections.
It is important to be aware of the
EUROPEAN DIRECTIVE on electromagnetic
compatibility when wiring up and installing
equipment on site.
Attention must be
paid to
ensure that the techniques used during
wiring/installation do not increase
electromagnetic emissions or decrease the
electromagnetic immunity of the equipment,
wiring or a
ny connected devices.
If in any
doubt
contact Flowserve for advice.
The motor must be wired up in
accordance with the motor manufacturer's
instructions (normally supplied within the
terminal box) including any
temperature, earth
leakage, current and other protective devices as
appropriate.
The identification nameplate should be checked
to ensure the power supply is appropriate.
A device to provide emergency stopping
must be fitted.
If pre-wired is not supplied to the pump unit, the
controller/starter electrical details will also be supplied
within the controller/starter.
For electrical details on pump sets with controllers
see the separate wiring diagram.
Direction of rotation has to be checked
with pump uncoupled.
4.7
Final
shaft
alignment
check
After connecting piping to the pump, rotate the shaft
several times by hand to ensure there is no binding
and all parts are free.
Recheck the coupling alignment, as previously
described, to ensure
no pipe strain.
If pipe strain
exists, correct piping.
Refer to section entitled
shaft/coupling
alignment
and perform a coupling alignment check as
outlined. This check is recommended to insure the
alignment has not been disturbed during the grouting
of the baseplate or while installing suction and
discharge piping.
4.8
Protection
systems
The following protection systems are
recommended particularly if the pump is installed in a
potentially explosive area or is handling a hazardous
liquid.
If in
doubt consult
Flowserve.
If there is any possibility of the system allowing the
pump to run against a closed valve or below
minimum continuous safe flow a protection device
should be installed to ensure the temperature of the
liquid does not rise to an unsafe level.
If there are any circumstances in which the system
can allow the pump to run dry, or start up empty, a
power monitor should be fitted to stop the pump or
prevent it
from being started.
This is
particularly
relevant if the pump is handling a flammable liquid.
If leakage of product from the pump or its associated
sealing system can cause a hazard it is
recommended that an appropriate leakage detection
system be installed.
T
o prevent excessive surface
temperatures at
bearings it is recommended that temperature or
vibration monitoring are carried out.
