Installation and operating instructions Wilo-Para MAXO/-G/-R/-Z
Only operate the pump with sinusoidal AC voltage.
A motor protection switch supplied by the customer is not required.
If a residual-current device (RCD) is used, it is recommended to use an RCD type
A (pulse current sensitive). Check that the rules for the coordination of electrical
equipment in the electrical installation are observed and, if necessary, adjust the
RCD accordingly.
When dimensioning the residual-current device, consider the number of pumps
connected and their rated motor currents.
Observe leakage current I
The following minimum requirements are to be met if shutdown takes place by
means of an on-site network relay:
–
Rated current ≥ 8 A
–
Rated voltage: 250 V AC
Observe the switching frequency:
–
Switching on/off via mains voltage ≤ 100/24 h
–
≤ 20/h for a switching frequency of 1 min. between switching on/off via
mains voltage
The mains cable is intended for the power supply of the pump.
Mains cables meet the requirements of DIN VDE 0292, DIN VDE 0293-308 and
EN 50525-2-11.
The mains connection at the pump interface is designed as an AMP Super-
seal 1.5 Series 3P CA (bush) with the following features (DEKRA conformity
number 2166328.01-AOC):
–
EN 61984
–
6 mm distance (grid dimension)
–
Mains rated voltage 250 V AC
–
Rated current 2.5 A
–
Frequency 50/60 Hz
–
Rated surge voltage 2.5 kV
≤ 3.5 mA for each pump.
