3.2 Motor Compatibility
NOTICE
Non-compatible motor
Risk of damage to the machine and the variable-frequency drive
• Make sure to use a compatible motor and approved by Busch.
The variable-frequency drive is only compatible with the following motor(s):
Motor type Power / Voltage Size Part no.
Three-phase 11kW / 400V AC 160L / B5-350 0632 700 013
Three-phase 15kW / 400V AC 160L / B5-350 0632 700 014
Three-phase 22kW / 400V AC 180L / B5 0633 700 016
Recommended motor rating (4-pole asynchronous motor) is specified on the 400V AC
supply voltage.
NOTE
Refer to the motor nameplate for specific technical information.
4 Transport
WARNING
Suspended load.
Risk of severe injury!
• Do not walk, stand or work under suspended loads.
Motor + VFD weight (approx.):
DOLPHIN LT 0320 A = 134kg
DOLPHIN LM 0530 A, LT 0430 A or LT 0510 A = 180kg
DOLPIN LT 0630 A or LM 0800 A = 195kg
VFD weight: 21 kg
• Check the motor for transport damage.

5 Storage
NOTICE
Long storage time.
Risk of damage to the variable-frequency drive!
Due to a long storage time the capacitors of the variable-frequency drive can lose effi-
ciency because of electrochemical processes. In worst case it can lead to a short circuit
and therefore to a damage to the variable-frequency drive.
• Connect the variable-frequency drive every 2 years for 30 minutes to the mains.
• Store the motor with the variable-frequency drive indoor, dry, dust free and if possible
in the original packaging preferably at temperature between -20 … 60 °C.
6 Installation
DANGER
Carry out any work on the variable-frequency drive and motor.
Risk of electrical shock!
• Electrical installation work must only be executed by qualified personnel.
DANGER
The installation conditions are not respected.
Risk of electrical shock!
Risk of severe injury!
• Take care that the installation conditions are met.
CAUTION
The machine can start immediately when power is supplied.
Risk of inadvertent start-up!
• Make sure that a start-up will not lead to a dangerous situation.
6.1 Installation Conditions
• Make sure that the variable-frequency drive is de-energised.
• Make sure that the variable-frequency drive is grounded in accordance with DIN EN
61140; VDE 0140, NEC and other relevant standards.
• Make sure that unused open cable ends in the motor terminal box are insulated.
• Make sure that mains connections are hardwired.
• Make sure to use suitable line circuit breakers with the prescribed nominal current be-
tween the mains and the variable-frequency drive, see Line Protection.
• Make sure that the ambient conditions are complied with, see Ambient Conditions.
