English
• When pumps are used in systems with water temperatures above 90°C, a suit-
able heat-resistant supply cable must be used.
• All connection cables must be installed so that they do not touch the pipe and/
or the pumps or motor housing.
• In order to ensure drip protection and strain relief on the threaded cable con-
nection, cables with a sufficient outer diameter (see Table 7.2) must be used
and must be screwed sufficiently tightly. In addition, the cables near the
screwed connection are to be bent to form a drainage loop, to drain any accu-
mulated drips. Unused threaded cable connections should be blanked off with
the sealing plates provided, and screwed tight.
DANGER! Risk of fatal electrical shock!
There may be dangerous contact voltage at the contacts of the IF Module
interface.
If no IF Module (accessory) is plugged into the module compartment, the
stopper (Fig. 7, item 1) must cover the IF Module interface so that it cannot
be touched. Make sure that it is seated correctly.
• Commission pumps only if they are fitted with the correct modular cover. Check
that the cover seal is correctly seated.
WARNING! Risk of injury and damage to property!
If the fan cover is damaged, the protection class and electrical safety are not
ensured. Check the seat of the fan cover.
• Assignment of the threaded cable connections:
The following table shows the possible combinations of electric circuits in a
cable for assigning the individual threaded cable connections. DIN EN 60204-1
(VDE 0113, sheet 1) must be complied with:
• Clause 14.1.3 as follows: Conductors of different electric circuits may belong
to the same multi-conductor cable if the highest voltage which may occur in
the cable is insulated sufficiently.
• Clause 4.4.2 as follows: Signal lines with low levels should be separated from
power lines if there is a potential risk of functional interference due to EMC.
