Three phase version
1. (8-10kVA THREE PHASE VERSION): Use 3 cables with 6
mm 2 section (EARTH, L2 and L3) and 2 with 10 mm 2
section (N, L1) in input (N.B.: L1 and N have a greater
section because in operation from bypass they have to carry
all the input current). For the output use 3 cables with 10
mm
2 section (EARTH, N and L). With reference to the figure
shown at the side:
- Insert the cables from the 63A magneto-thermal switch into
seal stop P2 (input line).
- Insert the cables from the load into seal stop P1 (output line).
- Strip the cables observing the measurements provided.
- Insert the part that has just been stripped into the ferrules
provided.
(6,5kVA THREE PHASE VERSION): Use 3 cables with 4
mm
2
section (EARTH, L2 and L3) and 2 with 6 mm
2
section
(N, L1) in input (N.B.: L1 and N have a greater section
because in operation from bypass they have to carry all the
input current). For the output use 3 cables with 6 mm
2
section (EARTH, N and L). With reference to the figure
shown at the side:
- Insert the cables from the 63A magneto-thermal switch into
seal stop P2 (input line).
- Insert the cables from the load into seal stop P1 (output line).
- Strip the cables observing the measurements provided.
- Insert the part that has just been stripped into the ferrules
provided.
2. Connect the wires to the relative terminals strictly
following the instructions set out below:
Input line
a - Ensure that the magneto-thermal switch upstream
is open.
b - Connect the earth wire to terminal 5.
c - Connect the neutral wire to terminal 1.
d - Connect the phase wires to terminals 2, 3 and 4
(use the red wire for L1).
Output line
a - Connect the earth wire to terminal 6.
b - Connect the neutral wire to terminal 7.
c - Connect the phase wire to terminal 8.
Bypass line
a - Ensure that a jumper is connected at terminals 9
and 10; this is needed for the correct operation of
the UPS.
3. Secure the cable guides to the flange, close the drawer and secure it with the screw removed previously.
