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.
Competence of the installer
The drive must be installed by professional assemblers who are familiar with the
requirements for safety and EMC. The assembler is responsible for ensuring that the
end product or system complies with all the relevant laws in the country where it is to be

Mounting methods

Unidrive SP size 1 to 6 can be either surface or through-panel mounted using the
appropriate brackets. Size 0 can only be surface mounted.
Refer to section 10.4 and section 10.5 on page 291 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.
