5 INSTALLING PERMANENT RECORDER UP-2210-R

The installation process involves fitting the recorder in an existing 19-inch cabinet at the selected

installation site. The recorder is also connected to existing instrument transformers and the chosen

communication equipment. Working with transformers must only be made by qualified personnel to

prevent injury during installation. We recommend making the connections to the measure core and

only in exceptional cases directly to the relay cores.

5.1 Location and fitting

UP-2210-R is designed to be installed in a 19-inch cabinet. You should think carefully about the

environment so that it is clean and dry and have a normal ambient temperature. The communication

with the unit can also influence where the unit is installed.

Figure 21

The figure above shows a UP-2210-R. The UP-2210-R can be used with all standard 3-phase

connection options, and can measure both line-to-neutral and line-to-line voltages.

Note: If the units are used with external/internal modem, keep in mind that phone lines are

easily affected by lightning. Modems usually don’t have lightning protection. Unipower

recommends that external lightning protection is installed between the phone line and

modem in exposed locations, in order to protect the unit from damages caused by

lightning.
