Installation
iPaul DM2000
Attach amplifier using sheet metal screws (at least M4 x 30) and mounting rail to suitable, well-ventilated location
on auto body. The heat sink of the amplifier can reach a very high surface temperature. Maintaining a sufficient
distance from temperature-sensitive parts is absolutely necessary.
Note:
Clamp the negative terminal of the battery before starting connection of amplifier. This undertaking
requires expertise and should be performed with careful attention to relevant safety standards.
All screws on the amplifier terminal must be unscrewed in an upward direction before connection of the current
supply and loudspeaker cables so that the screws do not obstruct the insertion of the cables. However, under no
circumstances should screws be completely unscrewed.
Note:
Important safety notice regarding danger of fire and injury.
Unscrewing or turning the screws on the amplifier terminal during active amplifier operation
(amplifier is in performance) should not be attempted. There is risk of a short-circuit between the
screwdriver and the heat sink occurring, which could be severely damaging to the amplifier and the
vehicle. Fire-related injuries could result from high electrical currents passing through the screwdriver.
Drilling out the amplifier terminal for the purpose of a cross section extension for cable insertion will
lead to damage of the electronics and will result in an immediate voiding of warranty.
