General instructions and guidelines for installing and using the MST electromagnetic ballasts, ignitors and capacitors.
The earthing terminal or bottom plate of electromagnetic ballast should be connected with the earthing terminal of luminaire.
The matching lamp type to be used in the application is specified on the ballast.
The mains supply voltage is shown on the ballast. Make sure supply voltage is correct. The operating range should be -8% /+6% of the rated voltage.
In order to protect ballast please replace SON or metal halide lamp when the lamp is at end of life (the behaviors of end of life lamp include flickering, cycling, difficulty of ignition, color shifting, etc.). To extend the lighting system lifetime, the digital ignitor is recommended.
The ballast is warranted for storage within air circulative environment where
no corrosive gas exist.
On transportation, careful attention must be given and exposure to rain, snow or water immersion and intense vibration are not allowed. Transportation/ storage pallets cannot be stacked on each other.
