Installation Instructions
IMPORTANT INSTALLATION INSTRUCTIONS
WARNING
TO REDUCE THE RISK OF SEVERE INJURY OR
DEATH TO PERSONS:
. READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2. Install only on a properly operating and balanced door. A door that is operating
improperly could cause severe injury. Have qualified service personnel make repairs
to cables, spring assemblies and other hardware before installing the operator.
3. Remove all pull ropes and remove, or make inoperative, all locks (unless
mechanically and/or electrically interlocked to the power unit) that are connected to
the door before installing the operator.
4. Installation of this door operator must be done by a qualified installer.
5. Verify that the operator is correct for type, size of door and frequency of use per the
operator specifications.
6. Install the door operator at least 8 feet (2,4 m) or more above the floor if the operator
has exposed moving parts.
7. Do not connect the door operator to the source of power until instructed to do so.
8. Locate the control station: (a) within sight of the door, (b) at a minimum height of
5 feet ( ,5 m) so small children cannot reach it, and (c) away from all moving parts of
the door.
9. Install the Entrapment Warning Placard next to the control station in a prominent
location.
0. For products having a manual release, instruct the end user on the operation of the
manual release.
. If you have any questions about the safety of the door operating system, do not install
the operator, contact Manaras-Opera at -800-36 -2260.

Electrical Wiring
WARNING
To reduce risk of SEVERE INJURY or DEATH to persons:
•All electrical wiring should be done by a qualified professional and in accordance to local
electrical codes.
•Always shut OFF the main power before performing any electrical intervention.
•Use proper wire gauge for incoming power line and for accessory connections.
•Install operator main circuit breaker next to operator for easy access for power shut-off.
•Use separate knockouts on operator control box for accessories and main power cables.
•Always separate low and high voltage wires.
•Operator should be properly grounded to the building ground and to the main power
supply ground lug.
•Always use suitable and appropriate rating circuit breakers for operator protection.
•Compare available power supply voltage to voltage on operator name plate prior to
electrical connection. Failure to connect appropriate power supply voltage may cause
serious damage to the operator.
NOTICE
•THE OPERATOR MUST BE ADEQUATELY PROTECTED AGAINST OVERCURRENT AND SHORT-
CIRCUIT.
•PLEASE REFER TO LOCAL ELECTRICAL CODE.
•PLEASE REFER TO NATIONAL ELECTRIC CODE (NFPA 70) ARTICLE 430 SECTION IV (430.5 /
430.52 / 430,53).
•PLEASE REFER TO CANADIAN ELECTRIC CODE (CSA 22. ) SECTIONS 28-200 / 28-206.
Guideline to determine the branch-circuit rating of the protective device [A]:
Time Delay Fuse: ,75 x FLA
Non-Time Delay Fuse: 3,0 x FLA
A fuse that does not exceed the next higher standard ampere rating shall be permitted.
Example: If FLA = 3,8A
•Time Delay Fuse: ,75 x 3,8A = 6,65A → Standard fuse to use: 0A
•Non-Time Delay Fuse: 3,0 x 3,8A = ,4A → Standard fuse to use: 5A
For technical support, please call -800-36 -2260 or visit www.manaras.com for more information
FLA = Full Load Amp

NOTICE
•The installer MUST test for proper connection and functionality of the operator and its accessories
before leaving the job site.
•The installer should also perform a demonstration for the end-user.
•Use materials as per NEMA guidelines and always follow manufacturers instructions for conduit
preparation.
.1 Control Enclosure Conduits and Fittings
Compared to NEMA enclosures, the NEMA 4/ 2 and NEMA 4X enclosures are not supplied with pre-drilled fitting
entry holes to attach fittings for incoming power and other different accessories. All appropriate holes and cuttings
should be performed by the installer.
Always use liquid-tight and flexible non-metallic conduits and fittings. Use appropriate cutting tools or jigs to cut the
entry holes. While inserting the conduit to the fitting, ensure that the gland is properly compressed and that the
conduit jacket is not cut or ripped anywhere, in order to avoid liquid from leaking-in.
. Low Voltage (Controls) and High Voltage (Power) Connections
. Route the power line wires either from
the right or from the left of the control
box, as shown in Figure 3.
2. Route all low voltage control wires, as
shown in Figure 3. KEEP LOW
VOLTAGE WIRES SEPARATE FROM
LINE VOLTAGE WIRES.
3. USE COPPER CONDUCTORS ONLY.

.3 Radio Receiver Connection
NOTICE
•The radio receiver should be located in a remote or protected area to avoid damage caused by liquid
immersion.
.3.1 External Single-Button Radio Control Receiver
In NEMA 4/ 2 and NEMA 4X applications, a terminal strip is not provided on the outside of the control box.
If a 3-pin radio control receiver is being used, appropriate terminals are provided on the terminal strip in order to
connect the radio receiver. Please refer to Figure 4 for wiring instructions.
