Functional description
The IMT-L4 provides automatic shutdown of multiple file servers supported by a single IMV
VICTRON UPS. Each file server must be running IMV VICTRON's shutdown software or
have its own integrated UPS monitoring and shutdown facility. To increase data security, the
UPS can be turned off after all the connected servers have been shut down safely.
In addition, the IMT-L4 is capable of supervising the connection between the UPS and
the IMT-L4. Please note that more than four servers can be supported by "daisy-chaining"
IMT-L4 units together. All signal connections are carried out free of potential.
Suitable uninterruptible power supplies (UPS)
The IMT-L4 is designed for use with all IMV VICTRON UPS with ComConnect interfaces.
