Cable Selection
For 1 phase supply (Sizes 1-3 only), 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. Phase sequence is not important.
For compliance with CE and C Tick EMC requirements, refer to online documentation.
A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the
Optidrive 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).
The cables should be dimensioned according to any local codes or regulations. Maximum dimensions are given in the
Rating Tables section of this Quick Start Guide.

Connections
Most general purpose motors
are wound for operation on dual
voltage supplies. This is indicated
on the nameplate of the motor. This
operational voltage is normally
selected when installing the motor
by selecting either STAR or DELTA
connection. STAR always gives the
higher of the two voltage ratings.
