4.4. Incoming Power Connection
Power should be connected to the L1 and L2 terminals for single phase drives, L1, L2 and L3 for three phase drives. Phase
sequence is not important.
For compliance with CE and C Tick EMC requirements, a symmetrical shielded cable is recommended.
A fixed installation is required according to IEC61800-5-1.
For units without an internal isolator / disconnect, 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.
Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to
the data in section
11.5. Output Power and Current ratings
. The fuses must comply with any local codes or regulations in place. In
general, type gG (IEC 60269) or UL type J, T or CC fuses are suitable (exception: Eaton Bussmann FWP series must be used for
size 6A & 6B IP20 models); however in some cases type aR fuses may be required. The operating time of the fuses must be below
0.5 seconds.
Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in
place of fuses, providing that the clearing capacity is sufficient for the installation.
When the power supply is removed from the drive, a minimum of 30 seconds should be allowed before re-applying the power.
A minimum of 10 minutes should be allowed before removing the terminal covers or connection.
The maximum permissible short circuit current at the Optidrive Power terminals as defined in IEC60439-1 is 100kA.
NOTE
For IP20 Frame Size 8 it is important that the input supply phase orientation is correct, i.e. L1>L1, L2>L2, L3>L3, failure to do so
will result in a “
Ph-Seq
"trip.
4.5. Input Chokes
The majority of the Optidrive Eco product range is based on a low harmonic solution using film capacitor technology to achieve
compliance with EN 61000-3-12 without the need for any additional equipment. This standard specifies limits for harmonic
currents for equipment connected to public low-voltage systems with input current > 16A and <= 75A per phase. It is important to
understand which models from the product range are of the low harmonic technology which is detailed below.
The Optidrive Eco three phase 200V (200-240V) input and three phase 400V (380-480V) input drives frame sizes 2 up to and
including frame size 5 are a lower harmonic drive using film capacitor technology.
In short, this means that the low harmonic drives do not require an input choke and should not have one installed – drives outside
of the above frame sizes and supply voltage / number of phases, could benefit from the use of input chokes if further harmonic
reduction is required.
The low harmonic drives must NOT be used with input chokes. Please see section
for a description of which drives fall into the low harmonic category. Input chokes may be required on the standard (non low
harmonic) drives to reduce the harmonics generated or if the incoming supply impedance is low or the fault level / short circuit
current is high.
NOTE
For IP20 Frame Size 8 the input current level will vary according to supply impedance. At minimum a 1% line choke must be
installed. Installing a 4% line choke further helps towards minimising harmonic current distortion and total current levels. 1% and 4% line
chokes are available.
