IMPORTANT SAFETY INFORMATION
This manual contains important safety and operating instructions. Before you use the power
supply, thoroughly read all the instructions and cautionary notes on the power supply and the
products you will be connecting to the power supply.
• Do not use the power supply near water, for example: a bathtub, sink, wet basement,
swimming pool or in the rain.
• Do not place the power supply on an unstable cart, stand or table. If the power supply falls, it
could injure a person or cause serious damage to the power supply.
• Do not overload power outlets or extension cords. An overload can result in re or electric
shock.
• Do not disassemble this unit; take it to a qualied service technician or contact Hitec RCD USA
support when service or repair is required. Improper reassembly may result in a risk of electric
shock or re.
• Do not use an attachment not recommended for this power supply as risk of re, electrical
shock or injury could occur.
• Never force an object into the slot in the power supply. It could touch dangerous voltage
points or short out parts, resulting in a re or electrical shock.
CAUTION - To reduce the risk of property damage or injury:
• Do not operate the power supply if it has been dropped or damaged in any way. Contact Hitec
RCD USA support for repair.
• The power supply should be operated only from a standard AC outlet that provides 100-240VAC
with a frequency range of 50/60Hz.
• To protect the power supply during a lightning storm or when it has been unused for a long
period of time, unplug it from the AC outlet. This will prevent damage to the power supply from
lightning and power surges.
• Unplug the power supply from the outlet before attempting any maintenance or cleaning.
• Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning and then wipe it dry immediately.
• If your power supply does not operate normally, particularly if any unusual sounds or smells are
being emitted, unplug it immediately and contact Hitec RCD USA support for repair.
