Checking Suitability of the drive.

Matching the drive to the Intended Power Supply

Check the drive rating label to ensure it matches the intended power supply, the label shows the

rated supply voltage and if the drive is suitable for single or 3-phase supply.

For three phase supply models, a maximum of 3% imbalance is allowed between phases.

If using an IT Supply network, or any power supply type where the phase to earth voltage may exceed the phase-to-phase voltage (such as ungrounded supplies), the internal EMC filter and surge protection must be disconnected before connecting the supply, location of disconnect screws shown below :

A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the drive and the main Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery).

For compliance with CE and C Tick EMC requirements, refer to section 9.6 EMC Compliant Installation.

Matching the drive to the Intended Motor

Invertek Drives always recommends that selection of the correct drive is based upon the motor full load current rating at the incoming supply voltage, noting that the drive has a maximum continuous overload capacity of 150% for 60 sec’s (200% for 4 sec’s), this must be checked to ensure that it matches the application requirements in terms of required acceleration times and load conditions.

The continuous operating current of the drive can be found on the drive rating label.

Suitable Environments

Ambient temperature range:

Operational : -20 … 50°C

Storage and Transportation : -40 °C … 60 °C

Max altitude for rated operation : 1000m (Refer to section 18.3.2 for Derating Information)

Relative Humidity : < 95% (non-condensing)

Note : Drive must be Frost and moisture free at all times

Installation above 2000m is not UL approved
