3.3 IMPORTANT when servicing
The VEX door must be opened to allow servicing and cleaning.
Disconnect the power by removing the plug from the socket before
opening the door.
The fan motors will run on for up to 5 minutes.

Weekly plan It is important to follow the instructions below when the weekly
plan is active:
Set ventilation to OFF.
If the HMI panel shows 0% (VEX is inactive)
and the unit is operating to a weekly plan when
servicing begins, there is a risk that the pro-
gram may change via a timer operation and re-
start the VEX unit.
Prior to servicing, always set the ventilation to
OFF via the user menu.

BMS unit or Web
server BMS unit or Web server operation: If BMS or Web server controls are used, they could override the OFF function and the VEX may
start up irregularly. To disconnect the BMS or WEB server con-
nection, you must remove the plug from the EXact2 main board.
Refer to the section on the terminal board in the Electrical Instal-
lation Guide.
3.3.1 Connect service panel
When connecting the service panel you are recommended to use an extra HMI panel
connected to the VEX at the connection box.
NB The socket on the side of the VEX is only meant for the service HMI. For permanent
connection of the HMI, use the external bus connector on the EXact2 main board.

Backup via the HMI panel
●Insert the USB plug in one of the web
server sockets
●Select menu Backup/restore
●It can take up to 20 seconds to establish
the connection to the USB
The backup file can only be saved on a USB
plug. Once the file has been saved it is not
possible to change the file name or type.
The file is named automatically as in this ex-
ample: backup_20110918.file
Backup via web server
Follow the backup/restore instructions in the
web server guide. The backup file may be
saved on any medium (USB, PC etc.).
A backup file saved via the web server may
be renamed, but the file type cannot be
changed.
NB
If a backup file has been saved from the web
server and then renamed, it cannot be re-
trieved (restored) via HMI until the name has
beenchanged back tothe standard form,see
"Via HMI panel".
If it is necessary to make backup files for sev-
eral VEX, it is recommended that each file is
saved on a separate USB flash drive or that
a folder is created for each VEX on which the
backup files can be saved.

4. Starting up the unit for operation
The Modbus connectors must not be connected or removed while the
units are powered up. Both Modbus units must be switched off before
making changes, otherwise the units may be damaged.
During commissioning, it may be necessary to work with the control
system boxes open. Components in these boxes must only be touched
with electrically-insulated tools.
Before doing any work on motor controls or motor cables and terminal
boxes, the power supply must be switched off for at least five minutes
to allow the capacitors to discharge.
Before any commis-
sioning begins
●Check that the supply voltage is connected
●Set the HMI panel to specialist mode. See section "Access codes for technician
and service menus"
