To avoid any heating of the output connector terminal (glowing
contact), the wires need to be properly fitted to the output
connector terminal.
▪ Only use the enclosed Phoenix Euroblock connector terminals
[3].

(AWG 10).
▪ Ensure all contact screws are properly tightened.
Recommended torque settings (min/max): 0.7/0.8 N×m.
▪ Ensure the fixing screws of the connector terminal are properly
fitted to the output connector socket of the device.
The amplifier is equipped with two Phoenix Euroblock connector
sockets (female), one for each pair of amplifier output channels
(A/B, C/D).
