Appendix 1
1. Installation in the USA and Canada
1.1 Electrical connection
1.1.1 Conductors
Use 140/167 °F (60/75 °C) copper conductors only.
1.1.2 Torques
Power terminals
Relay, M2.5: 0.5 Nm.
Input control, M2: 0.2 Nm.
1.1.3 Line reactors
Max line reactor size must not exceed 2 mH.
1.1.4 Fuse size/circuit breaker
If a short circuit happens the pump can be used on a mains
supply delivering not more than 5000 RMS symmetrical amperes,
600 V maximum.
Fuses
When the pump is protected by fuses they must be rated for
480 V. Maximum sizes are stated in table below.
Motors up to and including 7.5 kW require class K5 UL-listed fuses.
Any UL-listed fuse can be used for motors from 11 to 22 kW.
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 table below.
USA - hp
Europe - kW
1.1.5 Overload protection
Degree of overload protection provided internally by the drive,
in percent of full-load current: 102 %.
1.2 General considerations
For installation in humid environment and fluctuating temperatures,
it is recommended to keep the pump connected to the power
supply continuously. This will prevent moisture and condensation
build-up in the terminal box.
Start and stop must be done via the start/stop digital input
(terminal 2-3).
Subject to alterations.
Note
In order to maintain the UL/cURus approval,
follow these additional installation instructions.
The UL approval is according to UL508C.
