Below is an example / guide for the electrical installer for maintaining CLASS 2 wiring to
the Skyfan DC’s terminal block.
STEP 1.
Prepare the supply wires as
shown.
Note:
5mm bare copper (L & N), and
20-30mm single sheath (L & N) from the
double insulated supply cable.
20-30mm
5mm
Double Insulated supply cable
STEP 2.
Prepare the supplied plastic tubing
(or similar) to the same length and place over
the 20-30mm single sheath insulation as
shown below, so that only 5mm bare copper
is protruding.
Note:
Total outer diameter of each wire
should not exceed 3.00mm. Large diameter
will not fit into the terminal block.
STEP 3.
Lift the terminal latch clips and
FULLY insert the prepared active wires into
the terminal block on the mounting bracket,
and latch down the clip to lock the wires.
Note:
About 7-8mm of the plastic tube (or
similar) insulation will be inserted as well. The
total diameter of each wire should not exceed
3mm as mentioned in Step 2.
Note:
Ensure correct polarities, and ensure
the active wires are secured firmly into the
terminal block.
Fully Insert the
wires (including the
double insulated
heat tube section)
Approx 15mm
total.
Insert plastic sleeves over the
prepared active wires.
STEP 2. Prepare the Heat shrink tubes with the same length and place over the 20-30mm single sheath insulation as shown below, so that only the 5mm
bare copper sticking out.
Note: Heat shrink tube outer diameter to be 2.5mm – 3.00mm only. Large diameter will not fit into the terminal block. See Step
3
Insert heat shrink sleeves
over the prepare active wires
STEP 2. Prepare the Heat shrink tubes with the same length and place over the 20-30mm single sheath insulation as shown below, so that only the 5mm
bare copper sticking out.
Note: Heat shrink tube outer diameter to be 2.5mm – 3.00mm only. Large diameter will not fit into the terminal block. See Step
3
Insert heat shrink sleeves
over the prepare active wires
STEP 4.
Apply 3-4 layers of electrical tape
overlapping the heat shrink insulation and
the double insulation of the supply cable
as shown.
Apply 3-4 layers
of electrical tape
making sure to
overlap the area
where the wires
branch from the
double insulation of
the supply cable.
