STARTUP USING PC-TOOL
Direct connection to switch cabinet or socket
(traditional application)
ZTH EU as MP level converter
Description
The ZTH EU is also a potential-free interface between the USB
port of a PC and the Belimo MP bus. It is used to connect the
Belimo PC-Tool directly to the MP bus or directly to a program-
mable MFT drive.
Power supply
The ZTH EU is supplied with power by the USB port. The MP bus
voltage is obtained internally by means of DC/DC converter.
This is why no external power supply is necessary.
Driver
To be able to work with the ZTH EU, a suitable driver must be
installed on the PC. The driver can be downloaded from the
Belimo website (download section). After installation of the
driver, the ZTH EU device will log in to the PC as a virtual COM
interface.
Note
For connection to USB ports of PCs and BELIMO 24 V drives
only (to safety extra low voltage SELV or US class 2 feeds)
