1.4 Electrical connection
1.4.1 Conductors
Use 140/167 °F (60/75 °C) copper conductors only.
1.4.2 Torques
Maximum tightening torques for the terminals can be found in
section Torques, page 37.
1.4.3 Line reactors
Maximum line reactor size must not exceed 1.5 mH.
1.4.4 Fuse size/circuit breaker
If a short-circuit occurs, the pump can be used on a power 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 3 HP 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.
1.4.5 Overload protection
Degree of overload protection provided internally by the drive, in
percent of full-load current: 102 %.
Subject to alterations.
In order to maintain the cURus approval, follow
these additional installation instructions.
The approval is according to UL 1004-1.
