Important Information
DANGER!
Hazardous voltage!
Will cause death or serious injury. Turn off and lock out all power
supplying this device before working on this device.
To use the equipment flawless and safe, transport and store properly, install and start
professionally and operate as directed.
Only let persons work with the equipment who are familiar with installation, start and use and who
have appropriate qualification corresponding to their function. They must observe the contents of
the
instruction’s manual, the information which are written on the equipment and the relevant
security instructions for the setting up and the use of electrical units.
The equipment is built according to DIN / EN and checked and leave the plant according to security
in perfect condition. If, in any case the information in the
instruction’s manual is not sufficient,
please contact our company or the responsible representative.
To maintain this condition, you must observe the safety instructions in this instruction manual
titled “Important Information”. Failure to follow the safety instructions may result in death, personal
injury, or property damage to the equipment itself and other equipment and facilities.
Instead of the industrial norms and regulations written in this instruction manual valid for Europe,
you must observe out of their geographical scope the valid and relevant regulations of the
corresponding country.
The
analogue output connections, Y0 … Y4 inputs and Ethernet have each other no
isolation / insolation.
If a phase-angle control or trailing-edge control is connected to the analogue output
(OUT U+ I+), this control must have a reinforced insulation / safe disconnection to the
load / mains side.
A circuit-breaker or switch must be situated within easy reach of the unit and fused.
Inst
allation excess current protection should be ≤ 10 A.
When using phase-angle controllers / trailing-edge controllers comply with the specifications of the
grid operator.
External current transformers:
➢
External current transformers are required to measure currents.
➢
The secondary lines S1 (K) and S2 (L) must not be grounded.
➢
The secondary circuits of the current transformers must never be operated open
(dangerous electrical voltage)
For switching 3-phase rotating (motor-driven) loads, protection must be used.
