Preliminary Checks
To ensure safety and an efficiently operating automated sy-
stem, make sure the following conditions are observed:
• The gate structure must be suitable for automation. For
example, wheel diameter must be in proportion to the
weight of the gate to be automated, an upper guide
must be provided, mechanical stop limits to prevent the
gate derailing must be installed.
• The soil must permit sufficient stability for the concrete pad.
• There must be no pipes or electric cables in the pad
excavation area.
• If the operator is exposed to passing vehicles, install, if
possible, adequate means of protection against acci-
dental impact.
• Check if an efficient grounding is available for connection
to the gearmotor.

Foundation Plate Installation
1. Assemble the foundation plate as shown in Fig 4. The
foundation plate must be located as shown in Fig 5 (right
closing) or Fig 6 (left closing) to ensure that the rack and
pinion mesh correctly.
2. Prepare a concrete pad as shown in Fig.7, following the
suggested dimensions. It’s recommended to have the pad
a minimum of 4” above level grade to avoid any flooding
of the operator. The underground depth of the concrete
pad is determined by the soil condition and the local
building codes. Make sure the concrete pad is leveled.
3. Provide one or more conduit pathways for all power and
accessory connections. Extend the conduit about of 1/2”
above the level of the concrete pad.
4. After the concrete is poured in the forms and before it
has a chance to set, insert the foundation plate into the
cement and position it flush with the top of the concrete
and aligned with the top of the lower gate frame. Use the
dimensions shown in Figs 5 or 6 to align your foundation
plate. Allow the concrete to set for a minimum of two days
before installing the operator.
5. Route the wires in the conduits. To facilitate the connec-
tions allow for about 15” of extra length of cables out of
the conduit. Separate the high and low voltage wires in
different conduits.
