Preparing the Installation
Pre-Installation Check List
Check the gate. It
must
operate smoothly and freely. If necessary, lubricate the
hinges, adjust or repair the gate prior to operator installation. The gate
must
be
level.
Double check the size and weight of the gate to make sure that it is proper for
this application.
If wiring has already been installed, check to make sure it meets the following
specifications.
Wiring Specifications
Refer to Table 4 and Table 5 for wiring specifications.
A.
The distances shown are
measured in feet from the operator
to the power source.
B.
These calculations are based on
the National Electrical Code and
allows for a 5% voltage drop.
C.
Supply voltage must be within 10%
of the operator’s rating under load
conditions.
D.
These calculations are based on
stranded copper wire.
E.
It is highly recommended that only
90% of the distances shown be
used; this will allow for a 10%
safety factor.
F.
For dual units, the distance shown
should be cut in half.
G. All local codes must be strictly
adhered to.
It is very important that
operator is properly grounded.
H.
Do not run control wires in the same
conduit with power wires.
I.
Do not run multi conductor or parallel
conductor cable for controls.
J.
All power wiring should be dedicated
and protected.

NOTE:
Calculated using NEC guidelines. Local codes and conditions must be
reviewed for suitability of wire installation. Master/Slave units must be installed on
separate circuits.
