4.0 PRELIMINARY INSTRUCTIONS FOR USE
The module is designed to be installed on DIN 46277 rail (fig.1) in vertical position.
No operation on the module is allowed while it is power on.
It is forbidden to install the module near heat-emitting devices.
It is reccomended that the use and installation operations are performed by an
electrical-skilled technician because it is possible to be exposed to risk of
electrocution.
Z-SUPPLY module can achieve a very high temperature, so it is important to be
careful when using it.

5.0 INSTALLATION
Power off the module before cabling.
To install/remove the Z-SUPPLY on/from DIN 46277 rail, execute the following operations
(Fig.1a and Fig.1b)
5.1 Installation on/removal from DIN 46277 rail
INSTALLATION
1)Pull the four latchs (placed in the back-
side panel) outwards;
2) insert the module in a DIN rail free slot;
3) make sure that the IDC10-connector pins
are inserted on the slot correctly;
4) press the four latchs inwards.
REMOVAL
1) Pull the four latchs (placed in the back-
side panel) outwards, using a screwdriver;
2) pull out the module gently.
It’s important to insert the pins on the slot correctly because IDC10-connector is polarized;
this connection is facilitied by use of a female/male insertion between IDC10 connector and
DIN rail slot (Fig 1c and Fig 1d).

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):
2 2
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.

Before using 24 Vdc output through IDC10 connector, see Fig.1d and in Fig.1c. Through
IDC10 connector, Z-SUPPLY can power up to 15 modules.
6.3 24 Vdc-output by IDC10 for Seneca modules
As you can see in the fig.6, there is a
diode internally connected at the end
of the IDC10 output: so, it is possible
to connect more Z-SUPPLY modules
in parallel ONLY if the redundant
outputs are connected by IDC10.
IT IS FORBIDDEN to connect more
Z-SUPPLY modules in parallel using
the redundant outputs by screw
terminals (in alternative, connect a
diode at the end of the output, for
each Z-SUPPLY, externally).
All the connection shown in
fig.6 are internal, into the Z-
SUPPLY.
6.4 Output relay and «power good»
The output voltage equal to 24 Vdc is guaranteed by an internal relay, which enables the
output voltage only if the voltage between its terminals is greater than 23.5 V. If the output
voltage is supplied correctly, the LED «good» will be on; otherwise, if a over-loading occurs,
the LED «good» will be blinking. The relay contacts are available on the screw terminals M4
(normally open) and M6 (common).
