Attention!
Damage of the terminals due to high torque
The specified maximum torques must not be exceeded!
Ensure that the connected lines are fixed with the needed torque compliant to
EN 60999 for a safe connection. The needed torque depends on the type of used
lines and the maximum current.
3.3 Protection Housing and sealing
As indicated in image 1, the cover of the terminal blocks can be sealed after installation.
The assembled meter base and meter cover will be protected against unauthorized opening
with a manufacturer label (format 8x20 mm, corner radius 0.5 mm) on both sides of the hous-
ing
Important
Warranty and accuracy are void if sealing labels are removed.

8Functionality
8.1 Measurement
The meter measures one phase active energy +A with accuracy class B.
8.1.1 Instantaneous parameter measurements
The instantaneous values can be read out via RS485 interface.
● Voltage and current
● Power factor
● Active power
● Frequency
8.2 Fatal Error
The meter has implemented a self-monitoring system. If the meter recognizes improper op-
eration so that billing relevant values may not be used anymore, it displays “--FF--”. This sta-
tus will be indicated with current display items flashing (1Hz).
9RS485 Interface & Registers
Default Modbus settings:
Baud rate = 9600 (settable)
Device Address = 1 (settable)
Parity = Even
Stop bit, parity bit and data bit can be configured via Modbus as 8E1, 8N1 or 8O1.
