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.
