## Safety

- Wrist protection is IP67 equivalent; wire-harness section is IP65 equivalent; FD20 and FD18 control units are IP54 equivalent.
- Option OP-P6-016/-017 (J2-axis encoder connector protector) reduces the rating from IP67 equivalent to IP54 equivalent.
- Do not use liquids that degrade seal components, such as organic solvents, acids, alkalis, chlorinated compounds, or gasoline-based cutting fluids.
- Ambient humidity: 20–85%RH, with no dew or frost allowed; vibration: not more than 0.5G (4.9 m/s²).
- Altitude: up to 1000 m from sea level; ambient temperature must be reduced above the allowable altitude.
- Control unit ambient temperature rating: 0–40°C.
- Cleanroom use requires downward air flow and removal of dust/particulates plus wipe-down cleaning; the robot is not shipped in dust-proof packaging.
- Explosion-proof version is not available.

## Study notes

- Hollow wrist with internally routed cables reduces external cable interference and cable damage risk.
- Maximum static load torque for MZ35S: J4 110 Nm, J5 110 Nm, J6 60 Nm.
- Maximum moment of inertia for MZ35S: J4 5.0 kgm², J5 5.0 kgm², J6 1.5 kgm².
- Application cables: 24 wires, including wires for optional valves.
- Cleanliness: ISO Class 4 equivalent; noise level: 75 dB.
- Position repeatability is JIS B 8432 compliant.
- J1 can be ordered with an optional ±180° range.
- Control units FD20 and FD18 are named; no matching controller id is available.
- Applications listed: machine tending, material handling, palletizing, dispensing.
- Installation method lists floor, inverted, and angle; additional information also lists cleanroom, tabletop, and invert/ceiling mount.
- Maximum speed values are maximums and vary with work program and wrist load conditions.
