Approval Standards - Grundfos SEG Series Instructions Manual

The letter X in the certificate number
indicates that the equipment is subject to
special conditions for safe use. The
conditions are mentioned in the certificate
and in these installation and operating
instructions.
Special conditions for safe use of
explosion-proof pumps:
1. Bolts used for replacement must be
class A2-70 or better according to
EN/ISO 3506-1.
2. The pump must not run dry. The level
of pumped liquid must be controlled by
two stop level switches connected to
the motor control circuit. The minimum
level depends on the installation type
and is specified in these installation
and operating instructions. The pumps
can be used in duty cycles S3, halfway
submerged, or S1, fully submerged.
3. Make sure the permanently attached
cable is suitably mechanically
protected and terminated in a suitable
terminal board placed outside the
potentially explosive area. The power
cable plug may only be disconnected
by the manufacturer or his
representative.
4. The thermal protector in the stator
windings has a rated cut-out
temperature of 150 °C guaranteeing
the disconnection of the power supply.
The power supply must be reset
manually.
5. The IP68 rating is limited to maximum
10 m submersion depth.
6. The temperature range is limited to -20
to +40 °C for ambient temperature and
0-40 °C for liquids.
7. Contact the manufacturer regarding the
"d" protection type for pumps and for
information on the dimensions of the
flameproof joints.
8. The lock nut of the cable connector
must only be replaced with an identical
one.
