INSTALLATION—CONTROL PANEL INSTALLATION
WIRING NOTE: All wiring from the fused discon-
nect to the control panel, from the control
panel to the optional junction box and the
door, and from the conduit between the
control panel and the floor (if a floor loop is
used) must be supplied by the owner of
the door. The wiring and conduit must
meet all local and state building codes.
Wires leading from the door are labeled
with the terminal numbers that are associ-
ated with the control panel. The high and
low voltage lines must run in separate con-
duit — otherwise, the warranty will be void.
Use shielded wire as indicated on the
schematic. Also, if a wire cable is to be
extended or spliced, a like cable must be
used throughout the entire length of that
cable. Likewise, if a shielded cable is to be
extended or spliced, a like cable must be
used throughout the entire length of that
cable — otherwise, the warranty will be
void.
All conduit entering the control panel must
enter from the bottom of the panel. DO
NOT install conduit through the top or
sides of the control panel — otherwise, the
warranty will be void.
Remove the knockout plate along the bot-
tom of the control panel before drilling
holes for conduit.
IMPORTANT: If your door is to be mounted on
a freezer, mount the control
panel and the fused disconnect
on the warm side of the wall. It
may also be necessary for you to
install more than one fused dis-
connect. To ensure the equip-
ment is de-energized during
maintenance or service, turn off
all disconnects.
IMPORTANT: Protect the components inside
the control panel from metal
chips when installing conduit.
Seal inside the conduit and
panel if the conduit entering the
panel is coming from an area
having a different temperature
(warmer or colder) than the area
where the panel is located.
The schematics shown through-
out this manual are for informa-
tion purposes only. Due to
varying requirements of each
customer, a schematic has been
prepared for your particular door
and it must be used for this
installation. That schematic was
shipped inside the control panel.
The disconnect must be in the OFF posi-
tion and properly locked and tagged
before wiring of the control panel begins.
High voltage is present inside this control
panel. Do not touch the circuit board, elec-
trical components, or wiring inside this
panel with power applied.
You must wait at least five minutes after
power is turned off before you can begin
work on this control panel. The drive con-
trol inside the panel contains high-voltage
capacitors which take time to discharge
once power is turned off.
Also, the controller contains electrostatic-
discharge sensitive devices (ESDS). To
prevent damage to the control system, fol-
low all ESDS handling practices when
working in and around the control panel.
