Electrical connection
Conductors
Use 140/167 °F (60/75 °C) copper conductors only.
Torques
Line reactors
Maximum line reactor size must not exceed 1.5 mH.
Fuse size/circuit breaker
If a short-circuit occurs, the pump can be used on a
mains supply delivering not more than 5000 RMS
symmetrical amperes, 600 V maximum.
Fuses
When the motor is protected by fuses, they must be
rated for 480 V. Maximum sizes are stated in the
table above.
Motors up to and including 2.2 kW require class K5
UR fuses.
Circuit breaker
When the pump is protected by a circuit breaker, this
must be rated for a maximum voltage of 480 V.
The circuit breaker must be of the "inverse time"
type. The interrupting rating (RMS symmetrical
amperes) must not be less than the values stated in
the table above.
Overload protection
Degree of overload protection provided internally by
the drive, in percent of full-load current: 102 %.
Subject to alterations.
