RackPack 4
Please note and retain this information. Carefully read and follow all of the safety and oper-
ating instructions before you use the machine. Be doubly careful to follow all warnings and
special safety instructions noted in this manual and on the unit.
This manual provides all information needed to fit or exchange RackPack modules. Module
manuals do not contain information on fitting and exchanging modules. You need this manual
everytime a module is to be fitted or exchanged.
If the manual is not at hand, you can download it like any other SPL product manual at

Connections:
Only use the connections as described. Other connections can lead to health
risks and equipment damage.
Water And Humidity:
Do NOT use this machine anywhere near water (for example near a wash
basin or bath, in a damp cellar, near swimming pools, or the like). In such cases there is an
extremely high risk of fatal electrical shocks!
Insertion Of Foreign Objects Or Fluids:
NEVER allow a foreign object through any of the
machine’s chassis openings. You can easily come into contact with dangerous voltage
or cause a damaging short circuit. NEVER allow any fluids to be spilled or sprayed on the
machine. Such actions can lead to dangerous electrical shocks or fire!
OPENING THE DEVICE:
Open the device only to fit or exchange modules. The fitting and/or
exchange of modules should only be carried out by qualified persons. In the light of possible
physical damage or injuries any manipulation is at your own risk. In order to avoid exposure
to any residual voltage, the device should be disconnected from any power source at least 5
minutes before opening it. If you handle the device improperly or ignore the manual (part of
the delivery of the RackPack 4 frame) you risk to damage the device or expose yourself to an
electric shock. In these cases SPL electronics GmbH denies any responsibility.
Electrical Power:
Run this machine ONLY from sources which can provide proper power at the
prescribed rating. When in doubt about a source, contact your dealer or a professional electri-
cian. To be sure you have isolated the machine, do so by disconnecting the power cord from
your wall connection. Be sure that the power cord plug is always accessible. When not using
the machine for a longer period, make sure to unplug it from your wall power socket.
Power Cord Protection:
Make sure that your power cord is arranged to avoid being stepped
on or any kind of crimping and damage related to such event. Do not allow any equipment or
furniture to crimp this power cord.
Power Connection Overloads:
Avoid any kind of overload in connections to wall sockets,
extension or splitter power cords. Always keep manufacturer warnings and instructions in
mind. Overloads create fire hazards and risk of dangerous shocks!
Lightning:
Before thunderstorms or other severe weather, disconnect the machine from wall
power (but to avoid life threatening lightning strikes, not during a storm). Similarly, before
any severe weather, disconnect ALL the power connections of other machines and antenna
and phone/internet cables which may be interconnected so that no lightning damage or over-
load results from such secondary connections.
Air Circulation:
Chassis openings offer ventilation and serve to protect the machine from
overheating. NEVER cover or otherwise close off these openings. NEVER place the machine
on a soft surface (carpet, sofa, etc.). Make sure to provide for a mounting space of 4-5 cm/2
inches when mounting the machine in racks or cabinets.
Controls and Switches:
Operate the controls and switches only as described in the manual.
Incorrect adjustments outside safe parameters can lead to damage and unnecessary repair
costs. Never use the switches or level controls to effect excessive or extreme changes.
Repairs:
Unplug the machine and immediately contact a qualified technician when you think
repairs are needed – or when moisture or foreign objects may accidentally have gotten in to
the housing, or in cases when the machine may have fallen and shows any sign of having been
damaged. This also applies to any situation in which the machine has not been subjected to
any of these unusual circumstances but still is not functioning normally or its performance is
