Installation and cabinet guidance
Isolate the 100 V circuit before wiring. Select the exact conductor pair from the manufacturer connection table; the taps do not all share a single common conductor.
The available taps are 6, 3, 1.5, 1, 0.5 and 0.3 W. Insulate unused conductors individually and include the chosen tap in the amplifier load calculation.
Check the drawing for fitting and bonding requirements. The M6 bonding stud permits a maximum 2 Nm torque; protect wiring separately and preserve the IP66/IP67 seals.
