For indoor mounting
■
Basic safety measures
• Installation must be carried out by authorised specialist staff.
• Unplug from the mains before installation.
• Described amplifi ers are exclusively for installation of HFC networks up to 862 MHz.
• Any other use or failure to comply with these instructions will result in voiding of warranty coverage.
• The amplifi ers may only be installed in dry indoor areas. Do not mount on or against highly combustible materials.
• The amplifi ers must be provided with an equipotential bonding wire (Cu, at least 4 mm
• The safety regulations set out in the current EN 60728-11 and EN 60065 standards must be complied with.
• The amplifi er supply voltage is 230-V AC and is a serious danger to life in the event of direct physical contact!
• The only reliable method of disconnecting the amplifi ers from the mains is to unplug them.
• Do not touch live parts.
• The power plug must be easily operable as the means of cutting power to the amplifi er, meaning the wall outlet must be
close to the amplifi er and easily accessible
• The power must be cut when installing or removing the amplifi er.
• The amplifi ers must not be operated without the standard fi tted power supply unit guard cover. The cover must be
closed.
• No liquid-fi lled items may be placed on top of the amplifi ers.
• The amplifi ers must not be exposed to dripping or splashing water.
• Permissible ambient temperature -20 to +55°C
VOS 32/RA
■
Frequency-dependent amplifi cation due to integrated
interstage attenuation (3 dB pre-emphasis)
■
Integrated 5-65 MHz active/passive return path
(switchable with jumpers)
VOS 42/RA
■
Interstage equalisers connectable jumpers
(6 dB pre-emphasis)
■
Integrated 5-65 MHz active/passive return path that can be
switched off (switchable with jumpers)
The amplifi ers comply with the requirements in the EMC
Directive 2004/103/EC and Low-Voltage Directive 2006/95/EC
applicable at the time of shipping.
