Residual-current-operated protective device
Danger due to electric current
To ensure as high a degree of reliability as possible we recommend a release current of 300 mA,
where a residual current circuit breaker (type A) is used.
Residual current circuit breaker (type A)
Exception: All-current-sensitive fault current circuit breaker on the 3 ~ 230 V line
When connecting the device between two outer conductors,
“
all-current-sensitive
”
fault current circuit
breakers must be used (see EN 50 178, Art. 5.2).
5.7
Motor protection
Integrated overload protection, preceding motor protection device unnecessary (max. line fuse see
Technical data).
5.8
Analog input
“
E1
”
for setting speed
The device has an analog input for setting the motor speed. Connection
“
E1
”
/
“
GND
”
(R

Technical
data).
If the analogue input
“
E1
”
is not required for specifying the speed, this can reprogrammed as a digital
input.

•
Ensure correct polarity!
•
Never apply line voltage to analog inputs!

The motor always starts with at least 6 % of the rated speed and stops below 4.5 % of the rated speed
(providing that the
“

setting is
“

).
With the settings

it is possible to adapt the setting signal / speed character-
istic, e.g. for setting signal: 0...5 V, 2...10 V.
