It is very important that the motor is mounted on a firm foundation that can not move or become loose over time. The
foundation should be constructed from concrete. The size of the plinth should be about 300 x 300 mm square and about
200mm deep. The foundation plate supplied with the motor must be securely mounted to the concrete using coach
screws and plugs. The foundation plate can also be welded to the gate rail if need be. The concrete should be allowed
sufficient time to set before the motor is mounted onto the plate.
Allow concrete to set and then place the
foundation plate onto the concrete plinth

When anchoring the motor it is important to ensure that the following points are checked.
1. The electrical cable is in place.
2. The concrete is fully set.
3. The motor foundation mountings are secure and can not m ove or become loose.
4. The motor should be set level and parallel to the gate.
5. The motor must be set above the flood level or if this is not possible, a flood proof wall should be constructed
around the m otor.
After placing the motor onto the three jack-up
bolts, place the three clamping nuts and washers
over the bolts to clamp the motor in place. Use the
Nut Applicator as shown below.
