6.10 Connection to the housing
(MAXIMUS MHX)
To install electrical connections between
the products, use the communication
boxes by null, MBX or MBA, alternatively
use an explosion-proof junction box with
equivalent characteristics.

6.10.1 Connection of the solenoid valve
to the housing (MAXIMUS MHX)
The Washer relay in the MHX is suitable for
voltages up to 30Vac or 60Vdc. Turn off one
of the supply poles of the solenoid valve
via the Washer relay (terminal J11) of the
MHX. Consult the housing manual.
Connect as in the diagram below (Fig. 22, page 16).
The solenoid valve can be powered
to 24Vac or 24Vdc with an isolated
transformer or isolated converter.
The polarity of the voltage, applied to the
power terminal, is irrelevant.

6.10.2 Connection of the pressure
switch to the housing (MAXIMUS MHX)
The housing does not have a prearranged alarm
input.
