4.2.2 Safety Ground
This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building
steel (girder, joist), a floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety
regulations and/or electrical codes.
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this
terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to
connect the shield to the safety ground terminal.
4.2.3 Motor Ground
The motor ground must be connected to one of the ground terminals on the drive.
4.2.4 Ground Fault Monitoring
As with all inverters, a leakage current to earth can exist. The EC Titanium Drive is designed to produce the minimum
possible leakage current while complying with worldwide standards. The level of current is affected by motor cable length
and type, the effective switching frequency, the earth connections used and the type of RFI filter installed. If a GFCI (Ground
Fault Current interrupter) is to be used, the following conditions apply:
• The device must be suitable for protecting equipment with a DC component in the leakage current
• Individual GFCI’s should be used for each EC Titanium Drive
Shield Termination (Cable Screen)
The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this
terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to
connect the shield to the safety ground terminal.
4.3 Incoming Power Connection
The EC Titanium product range has input supply voltage surge suppression components fitted to protect the drive from line
voltage transients, typically originating from lightning strikes or switching of high power equipment on the same supply. EC
Titanium Drive models are Over Voltage Category III according to EN60664-1:2007. Auxiliary circuits must be Over Voltage
category II.
4.3.1 Power Cable Selection
For 1 phase supply, the mains power cables should be connected to L1/L, L2/N. For 3 phase supplies, the mains power
cables should be connected to L1, L2, and L3.
Cables should be dimensioned according to any local codes or regulations per Table 4-2. The cable must be sufficient to
carry the drive load current. Refer to Table 4-2 Electrical Rating Table.
For compliance with CE and C Tick EMC requirements, refer to section EMC Compliant Installation. A fixed installation is
required according to IEC61800-5-1 with a suitable disconnecting device installed between the EC Titanium and the AC
Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-
1, Safety of machinery). For UL compliant installation, cables must be rated for continuous conductor temperature of 75ºC,
copper only.
The EC Titanium Drive is designed for the incoming power rating listed below.
