Mechanical Installation

Safety information
Follow the instructions
The mechanical and electrical installation instructions must be adhered to. Any
questions or doubt should be referred to the supplier of the equipment. It is the
responsibility of the owner or user to ensure that the installation of the drive and any
WARNING
external option unit, and the way in which they are operated and maintained, comply with
the requirements of the Health and Safety at Work Act in the United Kingdom or
applicable legislation and regulations and codes of practice in the country in which the
equipment is used.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after
the AC supply has been disconnected. If the drive has been energised, the AC supply
must be isolated at least ten minutes before work may continue.
WARNING
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual
fault conditions, it is possible that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output terminals. If the drive has failed
in a manner that causes the display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult Control Techniques or their authorised
distributor.
When replacing the terminal covers the screws should be tightened with a maximum
NOTE
torque of 1 N m (0.7 lb ft).

Mounting methods

Unidrive SP can be either surface or through-panel mounted using the appropriate
brackets.
Refer to section 10.5 and section 10.6 on page 262 for drawings showing the footprint
of the drive and mounting holes for each method to allow a back plate to be prepared.
If the drive has been used at high load levels for a period of time, the heatsink can reach
temperatures in excess of 70°C (158°F). Human contact with the heatsink should be
prevented.
WARNING
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 10.8 on page 264. 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.
