Electrical Isolation
A suitable means of isolating the ZENER 8000-V from the electrical supply must be provided in accordance with
your local electrical code. In the event that a second supply is connected to the relay contacts on the control
terminal strip (or otherwise brought into the ZENER 8000-V enclosure), suitable marking must be applied to the
outside of the ZENER 8000-V enclosure by the installer to indicate the dual supply arrangement in accordance
with your local electrical code and other safety requirements. A means of isolating the second electrical supply
source will also be required.
Motor thermal protection
The ZENER 8000-V provides an electronic type thermal overload function that relies on the measured motor
current to estimate the thermal conditions of the motor. For enhanced motor thermal protection, thermistors
should be installed in the motor winding and wired to the appropriate trip relay. The ZENER 8000 Extended
Features Option provides a thermistor relay function and other features.
