– Pump to be mounted with the shaft
in the horizontal plane in such a way
that it is not stressed by the pipe-
work. Observe mounting positions
as shown in Fig. 1.
– The arrow on the pump housing
indicates direction of flow (Fig. 2,
Pos. 1).
Star- Z 25 /2 DM:
The motor terminal box must not face
downwards to avoid possible moisture
entry. If necessary, rotate pump head
after undoing the screws holding the
stator housing.
Take care not to damage the housing
gasket.
– Due care must be given that free
ventilation is not restricted to pumps
equipped or refitted with plug-in
modules.
Thermal insulation of pump, if applied,
must be restricted to the pumps hous-
ing only. Ensure that drain holes at the
motor flange remain fully open (Fig. 2,
Pos. 2).

5.2 Electrical wiring
– Electrical work to be car-
ried out by qualified and
licensed electricians in
strict conformity to ruling
national conditions and
local regulations.
– All wiring and external switchgear to
comply with ruling local regulations
(use of conduits, all-pole switches,
air gaps, etc.) in accordance with
the latest edition of IEE wiring regu-
lations).
– In order to preserve protection against
moisture entry and to ensure a firm
gland grip the mains cable must
have a sufficiently large outside dia-
meter (f.e. H 05 V V-F 3 (4) G 1,5).
– Cable leads to be routed in such
a way to avoid any contact with pipe
work and/or pump or stator housings.
– Check available power supply and
voltage.
–
Observe pump name plate data
– All wiring to be carried out according
to wiring diagram (Fig. 4/5):
– 4: 3~400/415 V,
2a:
non-overloading
– 5: 1~230/240 V,
2b:
non-overloading
– Observe locally ruling earthing regu-
lations.
