CAUTION
Risk of injury due to electrical shock !
A switch or circuit-breaker must be included in the installation, it must be suitably
located and easily reached, it must be marked as the disconnecting device for the
equipment.
The power must be achieved by a transformer in which the primary windings are
separated from the secondary windings by REINFORCED INSULATION, DOUBLE
INSULATION, or a screen connected to the PROTECTIVE CONDUCTOR TERMINAL.
It is required the installation of a fuse as overcurrent protection, it has to be positioned
between the system and the secondary of the transformer in the installation with the
following characteristics: V ≥ 30 VDC or VAC, Imax = 5.0A (ES. 5x20 5.0A) if used with 1
powerhead and V ≥ 30 VDC or VAC, Imax = 10.0A (ES. 10x20 10.0A) if used with 2
powerheads.
