Electrical Safety Issues - Meyer Sound 500-HP Operating Instructions Manual

CHAPTER 2: POWER REQUIREMENTS
NOTE: For best performance, the AC cable
voltage drop should not exceed 10 V, or
10 percent at 115 V and 5 percent at 230 V. Make
sure that even with AC voltage drops that the AC
voltage always remains within the operating win-
dows.

ELECTRICAL SAFETY ISSUES

Pay close attention to these important electrical and safety
issues.
The 500-HP requires a grounded outlet. Always use a
■
grounded outlet and plug.
Earth ground
Chassis ground
■ Do not use a ground-lifting adapter or cut the AC cable
ground pin.
Do not exceed the current capability of the 20-amp AC
■
Input connector for the loudspeaker. When looping loud-
speakers, consider the total current draw for all loud-
speakers on the circuit, including the first loudspeaker.
Make sure the AC power cable for the loudspeaker has
■
the appropriate power plug (on the other end) for the
area in which you will operate the loudspeaker. In addi-
tion, the AC power cable must be rated for the total cur-
rent draw of all loudspeakers looped from the power
source.
■ Do not operate the unit if the power cable is frayed or
broken.

to reduce strain on the connected AC power and audio
cables. Do not use the cable ring for any other purpose.
■ Keep all liquids away from the 500-HP to avoid hazards
from electrical shock.
