Safety Product Mechanical
Information Information Installation
In order to achieve IP54 rating (NEMA 12) for through-panel mounting, an IP54 insert must
NOTE
be fitted (size 1 and 2). See section 10.7 on page 293. Derating applies when the IP54
insert is fitted. Additionally, the gasket provided should be fitted between the drive and the
backplate to ensure a good seal for the cubicle. If the heatsink mounted braking resistor is
to be used with the drive through-panel mounted, please refer to the Braking Resistor
Installation Sheet supplied with the resistor prior to mounting the drive. For further
information refer to the Unidrive SP User Guide on the CD Rom supplied with the drive.
