N7GH2043MR NEMA 7 Gearhead Operator w/ Separate Wall Mount Control Box, 2HP, 460 VAC, 3 Phase, Right Hand

Logic 5.0 gearhead hoist commercial door operators employ lubricated gears for heavy industrial, high-cycle applications. These operators include a floor-level chain hoist for easy manual operation during an emergency or power outage.

Nema 7 Hazardous Area Modification (M105)

Modifies a door operator to meet specifications for hazardous locations defined by NEC Article 501, Class I, Divisions 1 and 2, Group D, and Article 502, Class II, Divisions 1 and 2, Groups F and G. The modification includes a hazardous area motor and separate Wall Mount Starter with intrinsically safe control circuit. Since the control circuit is intrinsically safe, control circuit components (limit switches, control station) are housed in general-purpose enclosures in accordance with NEC Article 504. A Dynamic Brake and Delay-on-Reverse Circuit are included with this modification. No friction clutch or solenoid brake is supplied on any door operator with this modification. 

The door operator must be factory supplied with this modification, not field modified. Specific NEC Article 501 and 502 specifications are required when ordering this modification. This modification comes wired B2.

NOTE: This modification is not compatible with many other modifications and accessories, such as photo eyes, auxiliary limits and radio controls. Typically used accessories include 2-Wire Electric Edges, Pneumatic Edges, 3-Button Stations and Door Interlocks. 

Connectivity

• MyQ® Technology enables you to securely monitor and control your facility door operator and lights from your smartphone, tablet, or computer for greater peace of mind.
• Alerts can be received as email or pop-up (push) notifications.

• Heavy-duty worm-gear-in-oil reducer delivers performance for heavy industrial, high-cycle applications.
• Floor-level chain hoist with electrical interlock provides easy disconnect and manual operation in an emergency.
• Control function selector dial allows easy selection and programming of seven wiring types—from constant pressure to close, to specialized Timer-to-Close functionality—to meet end user needs.
• Timer-to-Close conveniently and confidently closes the commercial door automatically after a predetermined time for added security and peace of mind.
• Mid-stop enables partial door opening to a preprogrammed position for energy savings, time savings, and convenience.
• Dual voltage connections increase flexibility by enabling the installer to select the required voltage within phase to meet job-site requirements. Within phases, voltage is selectable at installation with the placement of a connector.
• Continuous-duty high-starting torque motor with instant reverse and overload protection. Capacitor start with single phase, removable without affecting limit switches.
• Maximum run timer reverses or stops the door if closing time exceeds expected limits, reducing potential damage to door and operator.
• Delay-on-reverse circuit prevents abrupt reversal of door, minimizing wear on components.
• 3-Button Control Station with Maintenance Alert System (MAS).
• Drive reduction: 45:1 first stage using heavy-duty gears running in oil bath, cast-iron housing, and “all-climate” synthetic gear oil for improved low-temperature performance; #50 output sprocket chain.
• Bearings: sealed roller bearings in gear reducer.
• Brake: standard on all GH door operators.
• Construction: NEMA 1-rated electrical box, heavy-duty 11-gauge steel frame with durable powder-coat finish. All reduction sprockets are drilled and pinned to shafts.
• Door speed: 8–9 in. per second.
• Warranty: 2 years.

Safety

• Security+ 2.0™ radio receiver is standard on Logic 5.0 operators, virtually eliminating radio frequency interference.
• Accepts up to 90 one-button or 30 three-button remote controls, plus up to 30 wireless keypads or an unlimited number of DIP switch remote controls.
• LiftMaster® Commercial Door Operators comply with UL 325 standards.
• LiftMaster offers a variety of entrapment protection devices for every commercial application.
• Emergency disconnect allows manual lifting of the door in case of power loss or emergency.
