Installation points

（1） Mechanical installation

Position requirement: Install vertically inside the enclosed switchgear, leaving a minimum free space (100mm up/down, 5mm left/right; 120mm below with EMC shielding board).

Accessory installation: Before installing the optional modules (fieldbus, I/O terminals), power off and discharge are required, and touching the gold-plated contacts is prohibited; The depth of the bottom braking resistor (RB 5000) is increased by about 20mm, and the EMC shielding board can be replaced with a 24V braking module.

（2） Electrical installation

EMC measures: Separate power lines from signal lines, use shielded wires for motor cables with a large area of shielding layer, and shield brake resistor cables exceeding 30cm.

Power and protection: Use RK1 level fuses (such as Bussmann KTS-R series), and choose 300/500mA or delayed RCD circuit breakers.

DC link coupling: Only three-phase equipment can be coupled, and parameter A38 (set 1 for group 2/3) needs to be set. In case of a fault, the entire power supply needs to be disconnected, and fuses need to be replaced in pairs.

Safe torque shutdown: achieved through the ASP 5001 option, requiring dual shutdown (enable+option), with at least one functional test per month.
