Installation and operating instructions

Energy meter 3-phase CETS-A

via CT up to 1500A

Description

The CETS-A is a compact electronic active power energy meter for application in 3-phase power lines with power transformer measurement and neutral conductor. The well readable LCD display offers the reading of additional values like instantaneous power, total or per phase, as well as voltages and currents per phase.

Installation instructions

The 3-phase energy meter can be attached to a 35 mm rail (EN 60 715TH35).

The meter can be used only in installation cabinets with protection class IP 51 (dust-proof and water-proof).

Intended use

The local standards, guidelines, regulations and provisions should be complied with. The installation of the meter should be undertaken only by qualified and appropriately trained personnel.

Cleaning

The meter can be cleaned in dead state with a dry cloth or cloth soaked in soap solution. Do not use caustic or solvent-containing substances for cleaning.

Operation of the LCD display

The operating menu is shown as a graph on the backpage. The bridge Z1-Z2 should be removed for adjusting the transformer ratio.

Wiring diagram

The secondary, mains current transformer connection is to be connected to the phase to be measured. This connection is to be fused according to the local installation instructions.
