The unit measures currents, voltages and frequencies and
calculates following values:
•
Active, reactive and apparent power
•
Active and reactive energy
•
Harmonics and THD of currents and voltages
•
Programmable average value calculations
•
Four energy pulse outputs
Further, the unit includes 6 freely configurable digital or
analogue channels.
The unit communicates with other systems using common
protocols, such as the ModBus RTU, ModBus TCP, Profibus
DP, IEC 60870-5-103 and it can be connected to a fibre-optic
SPA bus.

Operating safety
The terminals on the rear panel of the relay may
carry dangerous voltages, even if the auxiliary
voltage is switched off. A live current transformer
secondary circuit must not be opened.
Disconnecting a live circuit may cause dangerous
voltages! Any operational measures must be carried
out according to national and local handling
directives and instructions.
Carefully read through the relay operation instructions before
any relay operational measures are carried out.
