6.2.1 Ambient temperature
CAUTION
Operation outside the permissible ambient temperature
Damage to the pump (set)!
▷ Observe the specified limits for permissible ambient temperatures.
Observe the following parameters and values during operation:
Table 14: Permissible ambient temperatures
Permissible ambient temperature Value
Maximum 50 °C
40 °C
7)
Minimum See data sheet
6.2.2 Frequency of starts
DANGER
Excessive surface temperature of the motor
Explosion hazard!
Damage to the motor!
▷ In case of explosion-proof motors, observe the frequency of starts specified in
the manufacturer's product literature.
The frequency of starts is usually determined by the maximum temperature increase
of the motor. This largely depends on the power reserves of the motor in steady-
state operation and on the starting conditions (DOL, star-delta, moments of inertia,
etc). If the start-ups are evenly spaced over the period indicated, the following limits
serve as orientation for start-up with the discharge-side gate valve slightly open:
Table 15: Frequency of starts
Motor rating Maximum frequency of starts
[kW] [Start-ups/hour]
≤ 12 15
≤ 100 10
> 100 5
CAUTION
Re-starting while motor is still running down
Damage to the pump (set)!
▷ Do not re-start the pump set before the pump rotor has come to a standstill.
