Non-electrical devices (e.g. hydraulics) also comply with EC
directive 94/09/EC.
Danger of explosion!
The housing of the hydraulics must be fully
submerged and flooded (completely filled
with the pumped liquid) during operation. If
the housing is not submerged and/or there is
air in the hydraulics, flying sparks may cause
an explosion e.g. due to static charge!
Ensure that dry-run protection is in place for
switching off.
4.3.1 Explosion coding
The Ex d IIB T4 explosion coding on the type plate indicates the
following:
- Ex = explosion-proof device complying to Euro norm
- d = ignition protection type for motor casing: Pressure-resis-
tant encapsulation
- II = intended for places where explosions may occur, with the
exception of mines
- B = intended for use with gases in sub-group B (all gases
excluding hydrogen, acetylene, carbon disulphide)
- T4 = max. surface temperature of the device is 275 °F
(135°C)
4.3.2 "Pressure-resistant encapsulation" protection type
Motors with this protection type are equipped with a tempera-
ture control system.
The temperature control system should be connected
in such a manner that, if the temperature limiter is trig-
gered, it can only be switched back on after the
release button has been manually activated.

Operating modes
4.5.1 Operating mode "S1" (continuous operation)
The pump can operate continuously at the rated load without
exceeding the maximum permissible temperature.
4.5.2 Operating mode "S2" (short-term operation)
The maximum operating period is given in minutes, for exam-
ple, S2-15. The pause must continue until the machine temper-
ature no longer deviates from that of the coolant by more than
2 K .
4.5.3 Operating mode S3 (interval operation)
This operating mode defines a combination of periods of opera-
tion and standstill. With S3 operation, the values given are
always calculated based on a period of 10 minutes.
Examples
- S3 20%
Operation 20% of 10 min ) 2 min/standstill 80% of
10 min = 8 min
- S3 3 min
Operation 3 min/standstill 7 min
If two values are given, they relate to each other e.g.:
- S3 5 min/20 min
Operation 5 min/standstill 15 min
- S3 25%/20 min
Operation 5 min/standstill 15 min
