MHT-CL/RCL
Installation and Maintenance Instruction:
4.1 The efficient and reliable grounding is a must not only for the personal protection, but
also for the proper use of electronic ballast to meet the national standard of EMC
without interference to other equipments.
4.2 The Luminaire shall be installed in the area with good ventilation, no corrosive gas and
no combustible and explosive objects.
4.3 The supply voltage is allowed to be varied at 110V-277V. It will influence the normal
start and operation of lamp and damage the electronic ballast if it is outside of this
range.
4.4 The maintenance can only be done after the power is cut off and the lamp is cold down
to prevent scald and electric shock accident.
4.5 Do not remove the lamp when power on.
4.6 The product shall be installed and serviced by the competent and certified electrician.
Note：1. The cover shall be replaced when it is cracked
. 2. The above data is subject to change without notice
Warning:
The efficient and reliable ground is a must when install Luminaire, to prevent
electric leakage and electric shock accident. End user should be responsible for the
consequence if against the instruction.

4. Installation and Maintenance Instruction
4.1 The efficient grounding is a must, not only for the personal protection, but also for the proper use of
electronic ballast to meet the national standard of EMC without interference to the equipment.
4.2 The Luminaire should be installed in an area with good ventilation, with no corrosive gas and no
combustible or explosive objects.
4.3 The supply voltage is allowed to be varied at +10% to -10%. It will influence the normal start and
operation of lamp and damage the electronic ballast if it is outside of this range.
4.4 The maintenance can be done only after the power is cut off and the lamp is has cooled down.
4.5 The product is to be installed and serviced by a competent and certified electrician.
4.6 The wiring inside the Luminaire is tool-free and it is not allowed to disconnect with the lamp while
the power is on.
4.7 The ambient temperature is allowed to be -20°F to +120°F
4.8 Operation while the glass cover is open is forbidden.
