Safety and operational standards

（1） Personnel qualification requirements

Transportation: Personnel who need to master the operation of electrostatic sensitive components;

Unpacking and installation: Electrical professionals;

Debugging: Professional personnel with knowledge of electrical and drive technology must comply with IEC 60364/60664 and national safety regulations.

（2） Key safety warning

Risk of electric shock: During equipment operation, there is a high voltage of up to 900V. After power failure, dangerous voltage may remain in the capacitor. It is necessary to wait for at least 5 minutes to confirm that the DC bus voltage is below 50V before operation; It must be reliably grounded (PE bus), otherwise it may cause fatal electric shock.

Hot air hazard: The surface temperature of the equipment may exceed 80 ℃, and it needs to be cooled to below 40 ℃ before touching to avoid burns.

Automatic restart risk: When the parameter AENA is set to 1, the device may automatically restart after power on, voltage drop, or power failure recovery. Warning signs should be posted and the dangerous area should be powered on when no one is present.

Prohibited scenarios: Not suitable for explosive environments, corrosive/conductive environments, non grounded/asymmetrically grounded power grids (voltage>240V), and ship/offshore applications; Using a servo amplifier alone to control the brake cannot guarantee functional safety and requires additional mechanical braking.

（3） Operation restrictions

It can only operate in a closed distribution cabinet, with an ambient temperature of 0-45 ℃ (rated 2.5%/K for 45-55 ℃) and an altitude of ≤ 1000m (rated 1.5%/100m for 1000-2500m);

Only use copper wire for wiring, and the wire diameter must comply with EN 60204 or NEC 310-16 standards (60 ℃/75 ℃ column).

Installation process

（1） Mechanical installation

Installation position: Vertically installed on the conductive grounding mounting plate, with reserved heat dissipation space around (such as 601-610 width of 70mm, above ≥ 40mm, below ≥ 70mm);

Fixing method: Use M5 hexagon socket screws (EN 4762) with a torque of 3.5Nm;

Protection requirements: Avoid approaching equipment with strong magnetic fields. The distribution cabinet should be forcibly ventilated to ensure that the ambient temperature is ≤ 45 ℃.

（2） Electrical installation

Wiring specifications: Power lines and control lines should be wired separately (spacing ≥ 200mm), motor cable length ≤ 25m (motor choke coil 3YL should be added if exceeding 25m), and both ends of the shielding layer should be grounded;

Key Connection:

Main power supply (X0A/X0B): 3-phase+PE, requiring external fuses (e.g. 6AT for 601/603, 10AT for 606/610, 20AT for 614/620);

DC bus (X7): Multi axis system can be connected in parallel, with a total rated current of ≤ 40A and a line length of ≤ 200mm (shielding is required for lines exceeding 200mm);

Motor (X9): including brake control (24V, max 2A), voltage drop needs to be confirmed;
