Safety Instructions
For important information about safety precautions for installation, refer to the product-specific operating guide.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors, which can remain charged even when the frequency converter is not powered. High voltage can be present even when the warning LED indicator lights are off. Failure to wait the specified time after power has been removed before performing service or repair work can result in death or serious injury.
- Stop the motor.
- Disconnect AC mains and remote DC-link power supplies, including battery back-ups, UPS, and DC-link connections to other frequency converters.
- Disconnect or lock PM motor.
- Wait for the capacitors to discharge fully. The minimum duration of waiting time is specified in .
- Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors are fully discharged.

Mechanical Installation
NOTICE
The guidelines in this instruction are applicable for a frequency converter in a standard configuration without any modifications.
Installing the blind cover
- Remove the front cover from the frequency converter and then remove the LCP, see Illustration 1.1.
- Install the blind cover with the gasket and the M12 connector.
- Install the front cover on the frequency converter, see Illustration 1.2.
Mounting the remote LCP
- Drill the hole in the wall that holds the LCP. The hole diameter: 24 mm ±1 mm (1 in ±0.04 in). To ensure that the base plate adjoins the wall, drill the hole perpendicular to the wall (±1°). The kit is suitable for insulated walls 30–90 mm (1.2–3.5 in) thick and solid walls 1–20 mm (0.04–0.8 in) thick.
- Install the base plate with the D-sub connector. Use the gasket and 4 self-tapping screws to secure the plate. See Illustration 1.3.

- Put the nut on the D-sub connector and tighten it with torque of 1.5 Nm (13 in-lb). Ensure that the base plate and the nut are tight on both sides of the wall. For very thin walls, the nut can also be turned 180°.
See Illustration 1.4 and Illustration 1.5.
