INSTALLATION RULES

The module has been designed for vertical installation on an IEC EN 60715 omega guide. For optimal operation and long working life, adequate ventilation must be provided. Avoid positioning cable ducts or other objects so that they obstruct the ventilation slots. Avoid mounting modules over equipment generating heat. Installation in the bottom part of the distribution board is recommended.

OMEGA IEC EN 60715 guide installation and removal.

Insertion onto the IEC EN 60715 guide:

1) Move the four hooks on the back of the module outwards as illustrated in fig. 1b.

2) Rest the module on the OMEGA guide.

3) To secure the module to the OMEGA guide, tighten the four hooks on the side of the IDC10 rear connector as shown in fig. 1a.

Removal from the IEC EN 60715 guide:

As shown in figure 1b:

1) Move outwards the four hooks on the side of the module, with the help of a screwdriver.

2) Extract the module from the guide.

Installation of the display panel (not present in the Z-FLOWCOMPUTER-B version)

Make a rectangular hole with the following dimensions:

W=119 mm x H=93 mm.

Insert the panel into the hole.

Secure the panel as shown in the figure using all the screws and fixing brackets supplied.

Be careful not to drop the panel while fixing it, so as not to damage it.

ELECTRICAL CONNECTIONS

Z-FLOWCOMPUTER module power supply

The power supply must be connected to terminals 2 and 3. The supply voltage must be between 10 and 40V  (any polarity), or between 19 and 28 V  .

The upper limits must not be exceeded in order to avoid serious damage to the module.

The power supply source must be protected from any malfunctions of the module through appropriately sized safety fuse.

Important: On first start-up, the module must be supplied without any interruptions for at least 72 hours to charge the internal batteries.

Micro SD card slot

The Z-FLOWCOMPUTER has a micro SD card slot on the side of the case.

Before insert the SD card in the matching slot, make sure the metal contacts are facing right (with reference to the side figure).

NOTA

BENE:

For the Z-FLOWCOMPUTER to working properly the micro SD card must be inserted .

RJ45 Ethernet port (on front)

Z-FLOWCOMPUTER has an Ethernet port with RJ45 connector on the front of the module, for display connection and/or for TCP-IP communications.

For further information, refer to the USER MANUAL.

USB micro port (side)

Z-FLOWCOMPUTER has a serial USB micro port.

This port allows module connection to a computer in order to configure it.

For further information, refer to the USER MANUAL.
