Mechanical Installation Requirements
All Optidrive Eco units are intended for indoor installation within controlled environments which meet the condition limits shown in section 1 1. 1 .
Environmental.
The drive can be operated within an ambient temperature range as stated in section 1 1. 1 . Environmental.
For IP20 units, installation is required in a pollution degree 1 environment.
For IP66 (Nema 4X) units, installation in a pollution degree 2 environment is permissible.
Electrical Installation Requirements
Incoming power supply connection must be according to section 4.4. Incoming Power Connection.
Suitable Power and motor cables should be selected according to the data shown in section 1 1.4. Output Power and Current ratings and the
National Electrical Code or other applicable local codes.
Motor Cable
Power cable connections and tightening torques are shown in sections 3.7. Mounting the Drive – IP20 Units, 3.9. Guidelines for Mounting (IP66
Units) and 3.8. Guidelines for Mounting (IP55 Units).
Integral Solid Sate short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance
with the national electrical code and any additional local codes. Ratings are shown in section 1 1.4. Output Power and Current ratings.
For Installation in Canada.
Transient surge suppression must be installed on the line side of this equipment and shall be rated X Volt (phase to ground), X Volt (phase to phase),
suitable for over voltage category iii and shall provide protection for a rated impulse withstand voltage peak of 2.5kV.
Where X is the supply voltage.
UL Listed ring terminals / lugs must be used for all bus bar and grounding connections.
General Requirements
Optidrive Eco provides motor overload protection in accordance with the National Electrical Code (US).

Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P4-12 = 1.

11.6. Internal EMC Filter and Varistors – Disconnection Procedure
11.6.1. IP20 Drive Models
All Optidrive ECO models provide a simple method to disconnect the internal EMC filter and surge protection varistors by fully
removing the screws shown below. This should only be carried out where necessary, for example in cases such as IT or ungrounded
supplies, where the phase to ground voltage can exceed the phase to phase voltage.
The EMC filter disconnect screw is labelled "EMC".
The surge protection varistors disconnect screw is clearly labelled "VAR".
