Before handling or connecting to the mains supply ensure
that all MSL products are protected from static discharge
and that the mains supply is to regulation. (230V +10
-6%)
Mains cables must be double insulated, strain relieved
and separated from E.L.V output cables.
This unit requires a constant current driver. 200mA Max.
Observe polarity:
Positive (+) is marked as RED.
Incorrect supply or reverse polarity can cause irreparable
damage.
All connections must be made before switching on mains.
If the supply is energised prior to making the connections
to the fitting then the resulting surge will damage the LED.
Multiple LEDs should be wired in series, refer to driver
instructions for minimum/maximum load.
