AC IN connector
This amplifier uses a NEMA L5-30 outlet.
Connect the 30 A twist-lock connectors by orienting the
locking L-shaped prong with the corresponding connector
entry, then fully insert the three prongs. Twist the plug
about 1/8 of a turn clockwise to lock the connector and
plug.
The amplifier requires very high-power so that it
can demand high current from the AC service.
Connections must be properly rated for reliable
operation.
If this device is to be rack mounted and trans-
ported frequently, be sure to support the rear end
of the unit with mounting hardware that matches
the size of the rack used.
