Free-standing enclosures provide for mounting the grounding
resistors internally. A wall-mounted enclosure requires a
separately-mounted grounding resistor. The “no enclosure”
option includes a door-mounted panel, a control panel and
a separately-mounted resistor assembly. (See Catalog Digit
10 to specify wire harness length.
Voltage of the distribution system.
Choose Wye when the neutral point of the power source is
accessible for direct connection to the grounding resistor.
Choose Delta when there is no neutral, or when the neutral is
not conveniently accessed. See page 2 for complete description.
The distribution system voltage and fault current will
determine the grounding transformer’s primary breaker
for Zig-Zag or Wye-Broken Delta systems. A Wye system
does not require this additional breaker.
Current-sensing.
Voltage-sensing.
Alarm contacts are standard in all assemblies.
A relay is connected across the output of the control
power transformer for customer use.
Standard lights are industrial, oil-tight, full-voltage type.
Optional are the same type lights except with a push-to-test
feature and/or transformer with 6.3V lamp.
Marks all internal wiring for ease of maintenance
Wiring from the door panel plugs to the left edge of the
control panel. Choose a harness length that will allow
for a hinge loop at the edge of the door.
