For better performance and long term functioning,
it is forbidden
to obstruct the Z-
SUPPLY ventilation openings (Fig. 2).
6.0 ELECTRICAL CONNECTIONS
6.1 Power supply
The electrical connections should only be
carried out on a disconnected module and
under ESD safe conditions.
Make sure that the Z-SUPPLY is power off
before executing any operations.
Before powering the Z-SUPPLY, it is
necessary to cable phase (P) and neutral (N)
of the single-phase network, through the
screw terminals 3 and 1.
Wire section (recommended):

0.5 mm -2.5 mm
6.2 24 Vdc-output by screw terminals
The output is available on the screw terminals
M7,M8,M9 (+24 Vdc) and M10,M11,M12
(0 V dc) as shown in Fig.4.
The output is protected against the current
over-load. If the output is over-loaded, Z-
SUPPLY protection system will be activated
automatically and output value is not stable
(hiccup). Protection status can be shown
through «good» LED (blinking light); in this
case, it is necessary to decrease the output
load. When the Z-SUPPLY is restarted, will be
reset automatically.
