Maintenance 171
Replacing the supply module (frame D8T)
WARNING! Only qualified electricians are allowed to do the work described
below. Read the complete safety instructions given in Safety instructions for
ACS880 multidrive cabinets and modules (3AUA0000102301 [English]) before
you service the drive. Ignoring the instructions can cause physical injury or death, or
damage to the equipment.
WARNING! Ignoring the following instructions can cause physical injury or death,
or damage to the equipment:
• Use extreme caution when maneuvering a supply 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 which is equipped with wheels, 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.
• Do not tilt the module. Do not leave the module unattended on a sloping floor.
• Wear protective gloves and long sleeves! Some parts have sharp edges.
• Do not use the module pull-out 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
cabinets).
