EURA E2000-0004 S2B, Safety Instructions And Operation Manual

Page: 9 / 82

1) Common installation rules and safety information regarding EURA E2000+ inverters
Basic rules for reliable and safe operation
-Proper dimensioning of the system (motor, inverter, mechanical elements).
-Check for correct inverters rated voltage, consider tolerances too
-Review all inverter and motor cabling, including correct terminal tightening
torque (torque values: see table).
-Use proper cable for all control wiring, separate control cable from power cable, min. 15 cm
distance. Use shielded cable for all control connections, exceeding 1 meter
-Twist wires to braking resistors or use shielded cables
-Shielded cables are recommended for motor connection too, especially with distances, exceeding 30
meters.
-Avoid earth loops, all earth connections should have large contact areas, all leading to one
central grounding point (star connected)
IMPORTANT FOR
SAVE INVERTER
OPERATION
One separate circuit breaker is recommended for each inverter
– allowing separate switch off of single inverters.
CHECK FOR PROPER INVERTER PROGRAMMING
Improper programming of the inverter may result in
unpredictable behavior of the system and subsequent high
risk of damage and/or personnel injury.
The inverter may be enabled for multiple automatic restart
attempts in case of fault
– delayed restart is possible.
Unpredictable systems reactions may become the result
of internal inverter defects.
The inverter may ignore commands, speed, STOP instructions,
or signals originated from external components.
The braking function of the inverter may fail.
Depending on the application, external safety
components, working independently from the inverter, are
required, to guarantee the safety of the whole system
Inverter protection-functions
Although the inverter is equipped with intelligent protections
functions, the repetitive triggering of those functions may result in
inverter damage.
The inverter is protected against output short circuit and earth fault,
each displayed by a specific code on the display.
Repetitive earth faults and short circuits may damage the
power stage of the inverter.
The motor must be fixed connected, in case, where interruption of the
motor line is required (for safety reason), the circuit should
open/close with inverter in STOP condition only (final stage disabled).
It is recommended, to keep the inverter powered on at all time, if
for application reason repetitive power on cycling is required, it
should not exceed one cycles every 5 minutes
– otherwise contact
the manufacturer.
