Installation and operating instructions Wilo-TOP-S/-SD/-RL/-I 31
English
The assignment of terminal boxes to the individual pump types is described
in the section "Terminal boxes" (chapter 6.2).
TOP-SD:
For a double pump the two motor impeller units are fitted identically and
accommodated in a common pump housing.
6.2 Terminal boxes
There are nine terminal boxes (fig. 4) covering all the pump types. Table 1 lists
the assignment of terminal boxes to pump types:
Table 1: Assignment of terminal box types to pump types (see also fig. 4)
The fittings for the terminal boxes can be found in Table 2:

1) The light indicator signals are carried by a common fibre optic cable to the cover, so that the signals are visible
from outside.
2) When mains voltage is present, the lamp lights up green
• The direction of rotation indicator light lights up green when mains voltage is
present and the direction of rotation is correct; if the direction of rotation is
incorrect, the control lamp goes out (see the chapter "Commissioning").
• The fault signal light lights up red if the integral motor protection has tripped.
