5.1General
Theele ctrical connectio n should be carried o ut by an
authorised electricia n in accordance w ith local
regulations.
Thes upply voltage , rated maxim um current and
cosap pear from the loose da ta plate that must be
fitted close to the installa tion site.
Ther equired voltage qual ity for Grund fos MS and
MMSsu bmersible motors, m easured at the motor
terminals, is – 10 %/+ 6 % of the nom inal voltage
during continuous oper ation (includin g variation in
thesu pply voltage and losse s in cables).
Furthermore, it must be ch ecked that there i s voltage
symmetry in the electric ity supply line s, i.e. same
difference of voltag e between the ind ividual phase s.
Seeal so 9. Checking of moto r and cable, point 2.
IfMS mo tors with a built-in tempe rature transmitter

ECEMC d irective (2004/1 08/EC). The capacit or
mustb e connected to the two p hases to which the

For37 kW MM S6 000, 110 kW MMS 8000
and170 k W MMS 10000, the maximu m
liquid temperature is 5 °C lo wer than

For190 k W MMS 10000, the
temperature is 10 °C lower.
Warning
Before starting wo rk on the moto r,
makesure that the electricity supply
hasbeen sw itched off and that it ca nnot
beacc identally switch ed on.
Warning
Themot or must be earth ed.
Themot or must be connecte d to an
external mains switch with a m inimum
contact gap of 3 mm in all poles.
Caution
Ifan MS motor with t emperature
transmitter is connected t o a frequency
converter, a fuse incorporate d in the
transmitter will melt and th e transmitter
willbe inactive. The transmitter cannot
bereac tivated. This mea ns that the
motorw ill operate like a motor w ithout
