4. See Figure 15. Disconnect the Ensto power connector (A), ground/earth strap (B) and control
connection (C) from the installed dimmer unit and remove the unit.
5. If you are installing an 80 V dimmer, and Voltaflex
adhesive insulation tape is not already stuck to the
panels in the fixture’s base as shown in Figure 16, stick
the two strips of tape supplied with the 80 V dimmer unit
to the panels using the two arrows in Figure 16 as a
guide. Position the tape so that it will prevent any
accidental electrical contact between the dimmer unit
components and the panels.
6. Place the new cover/dimmer unit next to the fixture and
connect the Ensto power connector (A), ground/earth
strap (B) and control connector (C). Connector locations
for the 80 V and IGBT multi-voltage dimmers are shown
in Figure 15.
7. Slide the cover/dimmer unit into the fixture, making sure that no wires are trapped, and tighten the four
screws in the cover.
8. Before applying power, check that the lamp voltage is correct for the dimmer type.
Important! The lamp voltage rating must match the dimmer output voltage. Installing a
lamp with an incorrect voltage rating may damage the dimmer beyond repair and/or
destroy the lamp as soon as power is applied:
• If the multi-voltage IGBT internal dimmer is used to power the lamp, the lamp voltage rating
must be the same as the voltage at the fixture’s power input.
• If the 80 V internal dimmer is used to power the lamp, the lamp voltage rating must be 80 V.
• Regardless of which internal dimmer is installed, if an external dimmer is used to power the
lamp, the lamp voltage rating must be the same as the output voltage from the external dimmer.
