Designated use and prohibition of misuse

Designated use: For the transportation of tooling fixtures, parts processing and transportation, environmental conditions and maintenance cycles must be followed.

Prohibited behaviors: carrying people, climbing scaffolds; Hyperparameter operation; Lack of safety equipment operation; Outdoor, explosion-proof, radioactive, and underground environments; Without the permission of KUKA, drilling and modifying the body directly results in the loss of all warranty.

The robotic arm is a semi-finished product and cannot be powered on separately for operation. The system integrator completes a complete risk assessment and issues an EC compliance statement.

Safety

Legal responsibility framework: KUKA provides assembly declaration; The integrator is responsible for the risk assessment of the entire machine, CE conformity declaration, and affixing CE markings; Unauthorized modification of the robot results in loss of compensation, and the responsibility for damage to third-party accessories belongs to the user.

Personnel classification: system integrator, operator, debugging and maintenance personnel, cleaning personnel. All personnel must read the complete safety chapter.

Area Definition

Workplace: Robot’s reachable range of motion;

Dangerous area=workspace+stopping distance (including external axis), must be physically fenced for protection.

The body comes with built-in protection: mechanical hard limit; Optional adjustable mechanical shaft limit; Brake release device (optional, emergency rescue only); The safety warning nameplate of the entire machine must not be torn off or altered.

After hitting the mechanical hard limit, it is prohibited to continue operating and KUKA evaluation must be contacted.

Safety points for each working condition

General safety: Do not stand under the arm; After a power outage, there is a risk of the arm falling and mechanical support is required; High temperature anti scalding of motor casing; Pacemaker personnel are at least 300mm away from the motor; dedicated personnel are responsible for controlling the teaching pendant; Modify the program hardware to prioritize T1 mode testing; The faulty equipment is powered off, locked, and tagged. After the control cabinet is powered off, the maximum internal high voltage is 780V, and it needs to wait for discharge.

Transportation: Maintain the prescribed transportation posture and avoid impact and vibration.

Start debugging: Change default password when powered on; The robotic arm controller must be paired and cannot be mixed; Complete safety circuit testing; Prevent condensation.

Manual mode T1/T2: T1 is used for teaching demonstration; T2 is only for high-speed testing and programming is prohibited.

Automatic mode: All protective devices must be in good condition and there must be no personnel in the danger zone before operation.

Maintenance and repair: power off, lock, and verify electricity; ESD anti-static; Refer to MSDS for hazardous chemicals.

Shutdown, storage, and disposal: comply with local regulations.

Project Planning

Planning risk warning: Long term temperature/power limits, high-frequency reciprocating, static loading, and external process forces can accelerate component wear and require shortened maintenance cycles. If necessary, consult with KUKA; The robot automatically stops when it exceeds the limit.

Two installation schemes

Installation on a concrete floor with a fixed base;

Installation of steel structure frame (positioning pin+bolt); The steel structure/concrete base must withstand all maximum foundation loads.

Cable and Interface Planning: Definition of Base A1 Interface; CTR-AIR and AIR-CTR-GIG energy supply systems; Cable laying cannot withstand tensile force, EMC electromagnetic compatibility; Equipotential grounding is necessary.

PURGE option planning: selection and prerequisites for four pressurization schemes A/B/C/D.

Transportation

Forced transport posture: The manual defines the angles of each axis, and when not fixed to the base, the robot must maintain a transport posture throughout the entire process.

Handling: lifting operations; Prohibition of savage impact; Provide the overall dimensions for transportation of the entire machine.

Startup and Re Debugging

Provide a complete description of the installation process for ground, wall, and ceiling robots:

Concrete foundation: The bottom plate positioning pin is in place, the robot lifts and lowers it, levels it, and diagonally locks the bolts step by step; After the first 100 hours of operation, tighten the anchor bolts again.

Steel structure frame: assembly of positioning pins, locking bolts for positioning.

Wiring operation: Define complete connectors for motor cables and data cables of KR C4 and KR C5 micro/micro-2 controllers; Complete equipotential conduction verification.

Key points for non ground installation: The installation tilt angle (ground 0-0-0, wall mounted 0-90-0, ceiling 0-0-180) must be entered in the WorkVisual software.

Mobile manipulator without driving conditions: brake release device, limited to emergency rescue only; ⚠️ The arm will fall in an unpowered state, and the arm must be mechanically supported before operation.

Maintenance

The maintenance cycle is based on standard operating conditions; Heavy duty high-frequency working conditions must shorten maintenance cycles.

Maintenance Summary Table: Tighten the foundation bolts for the first 100 hours; Regularly apply RB2 grease inside the cover plate; A3 and A5 synchronous belt replacement and tension adjustment; Body cleaning.

A3 synchronous belt replacement: mechanical locking arm body; Dismantle the cover plate, replace the belt, measure and adjust the tension using vibration frequency method; Reinstall the cover plate, perform axis zero calibration, and perform functional testing.

A5 synchronous belt replacement process; Tension measurement adjustment, zero point calibration.

Cleaning: Do not use high-pressure water guns or steam cleaning. Use solvent-free and non corrosive cleaning agents to prevent liquids from seeping into the gaps.

Maintenance

The manual only describes the replacement of fine fuses; Disassembly of other components such as joints, motors, and gearboxes is not covered in this manual and must be done by contacting KUKA service.

Shutdown, Storage, and Disposal

Shutdown and disassembly: move to the transport position; power failure; Remove all cable grounding wires; Lift the lifting device off the main body; All electrical connectors are protected against dust.

Long term storage: maintain transportation posture; Dry and dust-free environment without condensation; All interfaces are sealed and protected.

Scrap disposal: Metal recycling of cast aluminum steel; Classify motors and circuit boards as electrical waste; Lubricating grease, seals, and various consumables should be treated as hazardous chemicals; Follow local environmental regulations.
