Identification - Grundfos SE1 50 Installation And Operating Instructions Manual

Special conditions for safe use of
explosion-proof pumps:
1. Make sure the moisture switch and
thermal switches are connected in the
same circuit but have separate alarm
outputs (motor stop) in case of high
humidity or high temperature in the
motor.
2. Bolts used for replacement must be
class A2-70 or better according to EN/
ISO 3506-1.
3. Contact the manufacturer for
information on the dimensions of the
flameproof joints.
4. The level of pumped liquid must be
controlled by 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.
5. Make sure the permanently attached
cable is suitably mechanically
protected and terminated in a suitable
terminal board placed outside the
potentially explosive area.
6. The pumps have an ambient
temperature range of -20 to +40 °C and
a maximum process temperature of
+40 °C. The minimum ambient
temperature for a pump with a water-
in-oil sensor is 0 °C.
7. The thermal protector in the stator
windings has a rated switch
temperature of 150 °C and must
guarantee the disconnection of the
power supply; the power supply must
be reset manually.
8. The control unit must protect the WIO
sensor against the short circuit current
of the supply to which it is connected.
The maximum current from the control
unit must be limited to 350 mA.
9. For painted pumps, minimise the risk of
electrostatic discharge in the following
ways:
– Earthing is mandatory.
– In dry installations, keep a safety
distance between pumps and
walking paths.
– Use wet cloths for cleaning.
10. The WIO sensor is intended for use
only with a galvanically isolated circuit.
11. The lock nut of the cable connector
must only be replaced with an identical
one.

6.5 Identification

6.5.1 Nameplate
The nameplate states the operating data and
approvals applying to the pump. The nameplate is
fitted to the top cover of the pump.
