• You can install frames R1, R2, R3 and R4 tilted by up to 90 degrees from vertical
to fully horizontal orientation.
• Make sure that the hot exhaust air from a drive does not flow into the cooling inlet
of other drives or equipment.
• Drives equipped with the optional UL Type 1 kits: If you install the drives side-by-side,
make sure that their air outlets do not face each other.
Examining the installation site
Examine the installation site. Make sure that:
• The installation site is sufficiently ventilated or cooled to remove heat from the drive.
See the technical data.
• The ambient conditions of the drive meet the specifications. See the technical data.
• The wall behind the unit and the material above and below the unit is of
non-flammable material.
• The installation surface is as close to vertical as possible and strong enough to
support the drive.
• There is sufficient free space around the drive for cooling, maintenance, and
operation. See the free space specifications for the drive.
• Make sure that there are no sources of strong magnetic fields such as high-current
single-core conductors or contactor coils near the drive. A strong magnetic field can
cause interference or inaccuracy in the operation of the drive.
Required tools
To install the drive mechanically, you need the following tools:
• a drill and suitable drill bits
• a screwdriver or wrench with a set of suitable bits
• a tape measure and spirit level
• personal protective equipment.
