rial (pump housing made from red brass) and design conformity with the rele-
vant regulations (TrinkwV., ACS, WRAS, W3d, guidelines for creating potable
water installations).
If pumps of the series Wilo-TOP-Z in EN-GJL (pump housing of grey cast iron)
are used in domestic hot water circulation systems, the national regulations and
guidelines should be complied with as necessary.
6.2 Terminal boxes
There are seven terminal boxes (Fig. 4) for all pump types, which are assigned,
as per table 1, to the 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:
