106 Maintenance
Replacing the R8i DC/DC converter module
WARNING! Repeat the steps described in section Electrical safety
precautions on page 66. The complete safety instructions are given in
Safety instructions for ACS880 multidrive cabinets and modules
(3AUA0000102301 [English]). If you ignore them, injury or death, or
damage to the equipment can occur.
WARNING! If you ignore the following instructions, injury or death, or damage to
the equipment can occur.
• Use extreme caution when maneuvering a module that runs on wheels. The modules
are heavy and have a high center of gravity. They topple over easily if handled
carelessly.
• When removing a module which is equipped with wheels, pull the module carefully out
of the cubicle along the ramp. While pulling on the handle, keep a constant pressure
with one foot on the base of the module to prevent the module from falling on its back.
• When replacing a module, push the module up the ramp and back into the cubicle.
Keep your fingers away from the edge of the module front plate to avoid pinching them
between the module and the cubicle. Also, keep a constant pressure with one foot on
the base of the module to prevent the module from falling on its back.
• Wear protective gloves and long sleeves! Some parts have sharp edges.
• Do not tilt the module. Do not leave the module unattended on a sloping floor.
• Do not use the ramp with plinth heights over 100 mm. The ramp is designed for a
plinth height of 100 mm (the standard plinth height of Rittal TS 8 enclosures).
Support the top and
bottom of the module
while removing!
Do not tilt! Do not leave the module
unattended on a sloping floor!
