ID300/302 Integrated Motor Drive |
Connections
4 Connections
• All connection work must be performed in accordance with National Electrical Code and all local
electrical codes. This includes earthing to ensure that no directly accessible part of the ID300/302
can be at the mains voltage or any other dangerous voltage.
• The voltages on the cables or connections of the mains supply may cause fatal electric shocks.
Contact must be avoided in all circumstances.
• The ID300/302 must be supplied via a circuit-breaking device so that it can be powered down
safely. The power supply must be disconnected from the drive before the cover is removed from
the drive or before any maintenance is performed.
• The drive contains capacitors which remain charged at a fatal voltage even after the power
supply has been switched off. Wait 10 minutes after powering down the drive before removing the
protection devices.
• Special attention must be given if the ID300/302 is installed in equipment which is connected to
the AC supply by a plug and socket. The AC supply terminals of the drive are connected to the
internal capacitors through rectifier diodes which are not intended to provide safety isolation. If
the plug terminals can be touched when the plug is disconnected from the socket, a means of
automatically isolating the plug from the drive must be used (e.g., a latching relay).

The STOP and the Safe Torque Off functions
DO NOT
remove dangerous voltages from the drive,
the motor or any external option units.
• The drive power supply must be protected against overloads and short-circuits.
• It is vital to properly size all electrical circuit and motor protection devices per NEC and local
codes
• Connection with copper conductor only.
• Verify that the voltage and current of the ID300/302 and the mains supply are compatible.
•
DO NOT
touch the heatsink of the ID300/302 as it may become very hot during operation.
4.1 Terminal Block Access
Unscrew the 4 or 6 screws of the cover using a screwdriver (depending on drive model). Lift the cover.
• To maintain the IP55 protection of the ID300/302, it is essential to avoid damaging the seal while
removing the cover. Reposition the cover correctly when reassembling and tighten each of the 4
or 6 screws to the required 5Nm max torque.
• Adhere to the tightening torque to avoid damage to the threading.
