DANGER
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.
WARNING
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.
Caution
Direction of rotation has to be checked with pump uncoupled.
3.7 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.
Caution
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 base plate or while installing suction and
discharge piping.
3.8 Protection systems
explosive atmosphere
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
PUMPIRAN.
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.
