4.1: General Wiring Instructions
4.1.1: Electrical Codes and Warnings
Be sure that all wiring complies with the National Electrical Code (NEC) or its national equivalent,
and all prevailing local codes.
DANGER: Hazardous voltages.
!
DANGER
Exercise caution when installing and adjusting.
Failure to heed this warning can cause equipment damage, injury, or death.
Risk of electric shock.
!
DANGER
High-voltage circuits on J1, J2, and J3 are connected to mains power.
Failure to heed this warning can cause equipment damage, injury, or death.
Do not ground mains-connected circuits.
!
WARNING
With the exception of the ground pins on J1, J2, and J3, all of the other circuits on
these connectors are mains-connected and must never be grounded.
Failure to heed this warning can cause equipment damage.
Do not plug or unplug connectors with power applied.
!
WARNING
The connecting or disconnecting of cables while the amplifier has 24Vdc and/or
mains power applied is not recommended.
Failure to heed this warning may cause equipment damage.
4.1.2: Grounding Considerations
Primary Grounding Functions
A grounding system has three primary functions: safety, voltage-reference, and shielding.
J1-3 Primary Ground
The primary ground at J1-3 is the safety ground and is intended to carry the fault currents from the
mains in the case of an internal failure or short-circuit of electronic components. This ground is
connected to the amplifier chassis. Wiring to this ground should be done using the same gauge
wire as that used for the mains. This wire is a “bonding”’ conductor that should be connected to an
earthed ground point and must not pass through any circuit interrupting devices.
The pin on the amplifier at J1-3 is longer than the other pins on J1, giving it a first-make, last-
break action so that the amplifier chassis is never ungrounded when the mains power is
connected.
