Install the 450 MPS
Control Panel
Locate the control panel in the most convenient
position possible, considering the movement of the
gate. For example, a good position for the control
panel box is on the inner face of the post or pillar.
Figure 12 shows the typical layout for a two-leaf gate
with two 412 Operators.
Installing the control panel consists of the following
general steps:
•
Connecting the main power to the control
panel
•
Connecting an activating device
•
Connecting the operator(s) to the control
panel
•
Checking the motor’s direction of rotation
•
Connecting other devices (activating and
reversing) to the control panel
The installer is responsible for grounding the operator
systems, for providing the main power breaker switch,
and for making sure that the entire gate system meets
all applicable electrical codes.
Connect the Main Power Supply
WARNING
! Turn the main power off before
you make any electrical connections or set
any switches inside the control panel box.
WARNING
! The voltage of the main power
must match the required voltage of the 412
Operator and the 450 MPS control panel.
Wire the main power supply to control panel terminals
in block J1 (see Figures 13 and 14). The installer is
responsible for insuring that a separate, grounded
circuit protected by a circuit breaker is between the
control panel and the main power supply. All wiring
should conform to applicable electrical codes, and all
wiring and fittings should be weatherproof and/or
suitable for burial.
Connect the ground to the grounding terminal in block
J1 and connect the power wires to the terminals
labeled N (neutral) and L (phase).
Caution
: The operators are grounded only by
the grounded circuit the installer provides.
