Installation procedure

Safety instructions

• Please observe the applicable regulations for installation in the country where the current transducer is installed and operated, as well as the national regulations for accident prevention. Please also observe any internal company regulations, such as work, operating, and safety regulations.

• The technical specifications and limit values stated must not be exceeded under any circumstances. In particular, this applies to the specified ambient temperature range and IP protection category.

Siting location requirements

To ensure proper functionality, the conditions specified in the section “Technical specifications” must be observed.

Notes on assembly

• Be careful, check the transducer's maximum isolation voltage.

• The transducers can measure AC or DC current on any current wire. Check maximum allowed wire diameter.

• Check maximum distance for the current converter from the monitoring unit.

Installation

The transducer and the converter are installed together.

1. Mount the transducer using screws and nuts. Put the wire to be measured through the apperture hole of the transducer.

2. Connect one end of the RJ11 cable to any analog port (A1–A8) of the Vutlan monitoring unit and the other end to the RJ11 port of VT405 Current Converter.
