The VMS must be switched off when it is required to operate inside it without power, for example general
inspections or corrective maintenance. To do so, simply disconnect the main power supply from the
external electric panel board.
On the completion of the activity, the VMS needs to be reactivated. For which we can reconnect the main
power supply from the same external electric panel board.
After connecting to the main power supply, wait a few seconds for the CPU to reset all its functions.
Caution: if you shut off the main power to the VMS, make absolutely sure to check all
the connections before powering it up again, especially during maintenance.

All electrical and electronic components are modular parts which are mounted mechanically to their
relative mounting plates with the help of threaded inserts (integral part of mounting plates), spacers if
necessary with insulating material, and M3 and M4 locknuts.
To replace the parts like electronic boards, AC/DC power supply etc. simply use a 5.5mm or 7mm hex pipe
wrench.
The electrical connections of all the electronic boards are made with removable polarized connectors;
make sure that all these connectors are disconnected before pulling the board out.
Caution: malfunctioning or faulty parts may only be replaced with the equipment
powered off, and by properly trained technical staff.
While removing any faulty components or during general maintenance, it is necessary to follow the
procedure as given below:

Shut off the main power to the VMS as described in para. 7.3.

disconnect the electrical connector on the faulty device;

unscrew the locknuts/bolts of the faulty component; use a 5.5mm hex pipe wrench for LED
electronic board or 7.7 mm hex pipe wrench for AC/DC power supply;
