2.6 Potentially explosive environments
Use the explosion-proof S pumps in potentially
explosive environments. See section Ex approval
plate.
The explosion classification of the pump is
Ex II 2G, Ex db eb h mb IIB T3 or T4 Gb
(-5 °C to +40 °C) with a WIO sensor.
The installation must be approved by the
local authorities.
Special conditions for safe use:
1. Make sure the moisture and thermal
switches are connected in two sepa-
rate circuits and have separate alarm
outputs (motor stop) in case of high hu-
midity or high temperature in the motor.
2. Bolts used for replacement must be
class A4-80 or A2-80 according to
EN/ISO 3506-1.
3. The flame path gaps of the motor are
specified by the manufacturer and are
more narrow than the standard.
WARNING: In case of repairs, always
use original service parts from the
manufacturer to ensure the correct di-
mensions of the flame path gaps.
4. During operation, the cooling jacket,
when fitted, must be filled with the
pumped liquid.
5. The level of pumped liquid must be
controlled by level switches connected
to the motor control circuit. The mini-
mum level depends on the installation
type and is specified in this installation
and operating instructions.
6. Make sure the permanently attached
cables are suitably mechanically pro-
tected and terminated in a suitable ter-
minal board.
7. The WIO sensor must always be com-
pletely submerged in the oil when the
power is on.
8. If a WIO sensor is installed, the control
unit must protect the WIO sensor
against short circuit current. The maxi-
mum current from the control unit must
be limited to 350 mA.
9. The customer must inform Grundfos if
the pump has been exposed to any
harmful external effects or aggressive
substances.
