example, type B RCD according to EN50178, supplementary protector according to
UL1077, circuit breakers according to UL489, ground fault interrupter according to
UL943).
If the electrical supply to the system is connected through an Earth Leakage Circuit
Breaker (ELCB) or Residual Current Device (RCD) (depending on territory) it must be
applicable for:
▪ protection of equipment with a d.c. component in the fault current
▪ short duration switch-on surges
▪ high leakage current.
For example, type B RCD according to EN50178, supplementary protector according to
UL1077, circuit breakers according to UL489, or ground fault interrupter according to
UL943.
Electrical supply safety
WARNING: ELECTRICAL SAFETY
Risk of electric shock. Make sure that the electrical installation of the pump agrees
with all local and national safety requirements. It must be connected to a correctly
protected electrical supply and with a earth (ground) point.
WARNING: HAZARDOUS VOLTAGES
Risk of electric shock. This equipment is applicable for Installation Category II as
defined in IEC 60664-1. The system must be connected to an isolator that disconnects
all current carrying conductors and can be locked out in the off position (LOTO). The
isolator must be near the equipment, in easy reach of the operator and identified as
the disconnect device for the equipment.
WARNING: HAZARDOUS VOLTAGES
Risk of electric shock. Isolate the electrical supply before you disconnect the electrical
supply cable from the dry pumping system.
WARNING: HAZARDOUS VOLTAGES
Risk of electric shock. Make sure that the pump and electrical cables are correctly
protected against earth (ground) faults. Make sure that the earth (ground) conductor
of the electrical supply cable is longer than the phase conductors in the connector.
WARNING: PROTECTIVE EARTH CONDUCTOR
Risk of electric shock. Install a second protective earth (ground) conductor (with a
cross-sectional area as given in electrical connection
