5.8Connecting power supply

This section specifies the requirements for the mains power supply of the site.

WARNING

MAINS VOLTAGE!

Follow the national legislation when working with the power supply. DNT2Mi must be permanently wired to a disconnect device (for example circuit breaker) in accordance with the current local and national wiring standards.

The following warning applies to the AC power supply:

The protective ground wire can only be used for protective conductor installations. Using the protective ground conductor for other purpose is dangerous to life. Ensure that the ground connection is established before the power outlet is connected to the power interface.

The power supply of DNT2Mi can operate at the following voltages:

•90 to 264 VAC (AC-powered unit)

•-20 to -75 VDC (DC-powered unit)

•50 to 150 V (remote-powered via ACL2i).

Power interfaces are located on the rear panel of DNT2Mi.

AC mains is recommended to be protected with a lightning and transient overvoltage protector (mains wire-in protector). This protection is not included in DNT2Mi.

Note

In general, mains fuses and supply cables have to be rated according to the national electric safety regulations.

DNT2Mi can be connected either to a positive-grounded or to a negative- grounded DC power system. Principles of the DC power systems are presented in Figures 20 and 21.
