Replacing the D8T supply module
This section contains instructions on replacing the module from Rittal TS 8 enclosure. The
instructions are valid for the example Rittal installations presented in this manual. We
assume that you have the ABB module pull-out ramp in use (order code:
3AUA0000120467). If you do not have the ramp, always use a lifting device when you
remove the module.
WARNING! Only qualified electricians are allowed to do this work. Read the
complete safety instructions of the drive. Ignoring the instructions can cause
physical injury or death, or damage to the equipment.
WARNING! Be very careful when you move a supply module that runs on wheels.
Ignoring the following instructions can cause physical injury or death, or damage
to the equipment:
•
Do not move the module carelessly. It is heavy (approximately 175 kg) (386 lbs) and
have a high center of gravity. It topples over easily.
•
When you remove the module, use the module pull-out ramp. 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. We recommend that you attach a lifting device to the module before
you remove the module and keep it attached while removing.
•
When you install a module, use the module pull-out ramp. 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. We recommend that you attach
a lifting device to the module before you install the module and keep it attached while
installing.
•
If you lift the module, use only the two lifting eyes on top of the module: one in front
and the other in back. Never lift the module from the hole inside the module (visible
from top). It cannot carry the weight of the whole module. For the location of the lifting
eyes, see section
Layout drawing of D8T supply module on page 30 .
•
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 (3.94 in). The
ramp is designed for a plinth height of 100 mm (the standard plinth height of
Rittal TS 8 cabinets).
