II. Wiring Diagram
As shown in figure above：
HF output wire of the bulb can not be pressed, twitched
The user can not change the length of the cable.
Short-circuit of interior or exterior of the wire can
cause the damage of the lamp system.
Power supply wiring _ AC 220V, 2A (ampere)
cable_ (L & N)
The power supply wiring is the electrical connection
between the power supply and the electronic ballast
This wiring must always use a 3-core cable for phase,
neutral and grounding connections.
The phase and neutral of the power supply must be
connected to the connector block as described on the
HF output wiring
This wiring must be via the coaxial cable that is
supplied as standard with the power coupler.
Connections to the HF output of the HF electronic
ballast must be made according to the color-coding of
wires and the connector block.
The white wire must be connected to the +pole, and the
black wire to the -pole.
Changing or extending of the coaxial cable is never
As shown in figure above：
The bulb, HF electronic ballast and fixture must always
be grounded separately.
III. Tips for Thermal Conductivity and Resistivity
Keep the mounting flange of the power coupler at
non-contact position of 20mm distance away from the HF
electronic ballast for heat assistant reason.
Ensure good heat transport to the surroundings (heat
Use separate heat sinks for both the power coupler and
HF electronic ballast.
Avoid heat radiation from lamp to HF electronic ballast.
Mount the bottom of the HF electronic ballast housing on
its own heat sink; but never apply a heat sink for the
test point only.
Create a cooling airflow
Combination of a lamp, a power coupler and a HF
electronic ballast; all with the same wattage
Only system components with the same wattage indication
(100W or 130W or 160W or 200W) may be combined! Any
other combination might cause damage to the lamp system
Every HF electronic ballast may only be combined with
one lamp/power coupler set of the same wattage; failure
to observe this basic rule might cause damage to
lamp system components.
Ensure firm electrical contact between all metal parts,
the ballast housing and power coupler as well as correct
wiring connection before turning on the power.
Spec. of the power supply wiring: bearing capacity - 2A

For your safety, turn off the power before installation.
If an abnormal condition exists, turn off the power and
ask professional electrical technician for assistance.
Do not disassemble or attempt any repairs by yourself.

If the bulb shows red light and then turns off when the
power is on. That means the bulb is damaged.
