Commitment to technical excellence and dedication to quality is fundamental to Oerlikon’s success in the offshore oil and gas industry. Specifically, the line impedance must be greater than or equal to the ratio of the supply source transformer’s rating to the drive’s short circuit rating. Do use separate conduit for input power, output power, and control wiring. Precautions when switching Although switching a VFD from line power to a backup generator is an accepted practice in many applications, there are some limitations.

Caution: Make sure to remove power from the VFD prior to connecting the shield to the VFD’s ground lug. The output transformer has a 9V-0-9V, 2 Amps on the secondary and 230V on the primary. Install the control wiring in its own rigid steel conduit.
Here, the designer must run the drive with no motor leads connected for at least eight hours before trying to run the drive under load. Low-voltage dc control wiring and 120 Vac control wiring should be in separate conduits. Bussmann fast-acting current-limiting type fuses with low I2t values and 200,000 AIC rating (or equivalent) are recommended. Incorporating such a transformer is recommended when an installation is in close proximity to a substation.
