WARNING!
ATEX pumps in areas at risk from explosion
– Use a suitable motor protection switch to protect
power end motors. Use motor protection approved
for this application with Ex"e" motors. (Protection
against warming caused by overloading)
– Provide a time-delay residual current device.
– Ensure that motors are only installed and checked
by a "recognised competent" person in areas at
risk from explosion.
– Cleanly earth the motor via the mains cable.
– Observe the enclosed operating instructions for the
Ex motor, especially the maintenance plan.
CAUTION!
The motor can be damaged
Provide appropriate motor protection devices (e.g.
motor protection switch with thermal overcurrent trip)
to protect the motor against overloading. Fuses do not
provide motor protection.
CAUTION!
Pump can be damaged
The pump can be damaged if the motor drives the
pump in the wrong direction.
– When connecting the motor, pay attention to the
correct direction of rotation - refer to the "Start Up"
chapter.
Use an electrical isolating device in the mains supply
cable, such as a mains switch, to switch off the pump
independently of the entire installation (e.g. for
repairs).
1.
Install a motor protection switch, as the motors have no fuse.
2.
Install an emergency cut-off switch or include the motor in the
system's emergency cut-off management scheme.
3.
Connect the motor to the power supply.
–
Key motor data can be found on the nameplate.
