Absolute encoder connection
Caution!
Never touch the connection contacts on the position absolute encoder or on the cable! The electronics can be
destroyed by static electricity.
"
The absolute encoder must be connected to the frequency inverter.
"
The absolute encoder contains components that may be damaged by electrostatic discharge.
The body of the person touching them must
fi
rst be discharged, for example, by touching a
conductive, earthed object, (e.g. bright metal parts of a control panel), immediately beforehand.
"
A shielded cable must be used for the encoder connection. It is recommended to use a ZIEHL-
ABEGG SE cable which guarantees a suf
fi
cient shield connection.
"
The absolute encoder must not be detached mechanically in order not to lose the factory
settings. If the absolute encoder has been detached, the new encoder-offset has to be deter-
mined with the frequency inverter. Please see the inverter operation instructions for this proce-
dure.

Brake connection
"
Please also refer to the operating instructions of the brake.
"
The brake is designed for static applications only. Any dynamic braking must be re-
stricted to emergency braking and test braking. At static use, there is no brake wear.
Therefore the brake is almost maintenance free.
"
Open the brakes:
If exist, Electrical release of the brakes with a supply by accumulators/UPS is possible.
Mechanical release of the brakes is possible. Hand release version is available as an
option. Retro
fi
tting the hand release is not possible.
"
Dimension the supply and the wiring adequate for the 24 V brake. Brake current about 4,7 A per
circuit!
"
The terminal box for the brake may be removed from the motor and mounted on site for a better
attainability.
"
The brake is only allowed to be supplied with power when fastened to the motor and after having
connected the protective conductor of the motor at the control and the motor side.
"
The brakes have to be protected against over voltage from switching by varistors. The brakes
are supplied with varistors ex factory.
"
The brake release monitoring has to be evaluated; otherwise the type certi
fi
cate is not
ful
fi
lled! The change of state of both brake circuits have to be monitored separately.
"
The hand release acts on both circuits simultaneously. A separate release of the single
circuits for testing urposes is not possible.
"
The brake release monitoring is realized by micro-switches. Please assure with adequate wiring,
that the contact-current is at least 10 mA to keep the contacts clean.
