 U L rated ingress protection ("Type" ) is only met when cables are installed using a UL recognized bushing or fitting for a flexible-

conduit system which meets the required level of protection ("Type").

 F or conduit installations the conduit entry holes require standard opening to the required sizes specified per the NEC.

 N ot intended for installation using rigid conduit system.

Power Isolator Lock Off

On the switched models the main power isolator switch can be locked in the 'Off' position using a 20mm standard shackle padlock

(not supplied).

3.6. Removing the Terminal Cover

To access the connection terminals, the drive front cover needs to be removed as shown.

IP66 / Nema 4X Units

Removing the screws on the front of the product allows access to the connection terminals, as shown below.

3.7. Routine Maintenance

The drive should be included within the scheduled maintenance program so that the installation maintains a suitable operating

environment, this should include:

 A mbient temperature is at or below that set out in section 10. 1 . Environmental.

 H eat sink fans (where fitted) freely rotating and dust free.

 T he Enclosure in which the drive is installed should be free from dust and condensation; furthermore ventilation fans and air filters

should be checked for correct air flow.

Checks should also be made on all electrical connections, ensuring screw terminals are correctly torqued; and that power cables

have no signs of heat damage.

The Optidrive E3 may be limited to a maximum speed of 25.0 due to one or more of the following reasons:

1. Speed Reference Input (P00-03) – The speed reference input might be lower than expected, causing the drive to operate at a reduced speed.
2. Current Limit Reduction – If the overload accumulator reaches 90%, the output current limit is reduced to 100% of P-08, which could restrict the speed.
3. Analog Input Scaling – If an analog input is used for speed control, its scaling or signal level might be affecting the speed.
4. Alternative Ramp Time (P-24) – If P-24 is set and conditions apply, it could be affecting acceleration and deceleration speeds.
5. Derating at High Altitude or Temperature – If the drive is operating above 1000m or in high ambient temperatures, it may be derated, limiting performance.

Checking these factors and adjusting settings accordingly should help resolve the speed limitation.
