E 1145 - JOAP

Page 5 of 16 Warnings Before the drive is taken into use, verify that the specifications of the drive are compatible with the mains to which it is going to be connected. Furthermore verify that the motor is suitable for drive connection and that it is in compliance with the specifications of the drive. Check the place of installation for any special requirements and precautions which must be observed during installation, commissioning or operation. The drive must be supplied through a mains switch with at least 3mm breaker space between all conductors according to IEC364. The fuse installed in the electrical switchboard must be 16A or less for SpeedControl 1145. The drive must always be connected to yellow/green grounding conductor (PE) in supply. If the drive is connected to an installation with a residual current device as an extra protection, the device must be marked with minimum the following symbol: HPFI/PFI Class A Si The components of the power unit of the drive are live when it is connected to mains. Coming into contact with this voltage is extremely dangerous and may cause death or severe injury. The control unit (connection 5-8) is isolated from the mains potential. The motor terminals U, V and W are live when the drive is connected to mains, even when the motor is not running. The HW Stop terminals 1 - 2 and LS terminals 3 - 4 are NOT isolated from the mains potential. The earth leakage current may exceed 3.5 mA AC when the drive is connected to a motor. According to standard EN61800-5-1 a reinforced protective ground connection must be mounted. If the drive is part of a machine solution, the machine manufacturer is responsible for providing the machine with a main switch. (EN60204-1). If the drive is disconnected from mains while the motor is running, high and dangerous voltage may still be present on the power unit of the drive. In this case the motor is operating as a generator supplying the drive with power. After disconnecting the drive from mains, wait minimum 30 minutes before handling the drive. The drive may automatically start the motor after a fault situation or after re-connection of mains. Note that there might be a minimum downtime during which the motor cannot be stopped. In a domestic environment this product may cause radio interference in which case supplementary mitigation measures may be required. Intended for use in first environment, that includes domestic premises, it also includes establishments directly connected without intermediate transformers to a low-voltage power supply network which supplies buildings used for domestic purpose.
