SV-100SF-JBOX
24 V~ Junction Box Transformer
Input: 120 V~ 60 Hz 0.73 A Output: 24 V~ 60 Hz 3.1 A Class 2 (PELV)
Please read before installing.
Description
The SV-100SF-JBOX, see Figure 1, is a 24 V~, Class 2
junction box mount transformer that is used with a
Sivoia
or
Sivoia QED motorized roller blind. The transformer
provides enough power for one
Sivoia or Sivoia QED
Electronic Drive Unit to operate a 100 square foot
(9.29 m
2
) shade (225 square foot (20.9 m
2
) for a high
torque Electronic Drive Unit). The transformer is designed
to be mounted on a junction box in a remote location away
from occupants. The transformer contains a circuit breaker
on the primary side to protect the device in the event of
a miswire..
Caution - All wiring must be in accordance with
national and local electrical codes.
Danger - Locate and lock supply breaker in the
OFF position before wiring.
Caution - Do not short the output AC terminals.
Caution - Ensure that the earth ground is
connected to the
Sivoia or Sivoia QED Electronic
Drive Unit.
Installation
Note: Each transformer can power only
one
Sivoia or
Sivoia QED Electronic Drive Unit.
1. Turn power OFF at the circuit breaker.
2. Run 120 V~ power wiring to the transformer. Run
120 V~ power wiring through the junction box that the
transformer will be mounted on. Connect the hot and
neutral wires of the 120 V~ power wiring to the two
black primary wires of the transformer. Use appropriate
wire connectors to securely fasten and protect the wire
connections. Connect earth ground to the junction box.
See Figure 2.
3. Mount the transformer to the junction box.
Align the 4 in. by 4 in. (101 mm x 101 mm) metal plate
on the junction box opening so that the slots line up with
the screw holes. Fasten the transformer plate to the
junction box by using appropriate screws through the
slots and junction box screw holes.
4. Run 24 V~ power wiring to the transformer. Run the
low-voltage power wiring from the Electronic Drive Unit
to the quick connect tabs on the secondary side of the
transformer. Use quick connect lugs on the low-voltage
power wiring to properly connect the wiring to the trans-
former tabs. Connect the earth ground wire from the
Electronic Drive Unit to the grounded junction box.
5. Restore power. Note: If the Electronic Drive Unit does
not power up after restoring power to the transformer,
press the circuit breaker reset button located on the
transformer.
