Preparations For Use - Siemens 1LA8 Operating Instructions Manual

Preparations for use

Good planning and preparation of machine applications are essential in terms of keeping
installation simple and avoiding errors, ensuring safe operation, and allowing access to the
machine for servicing and corrective maintenance.
This chapter outlines what you need to consider when configuring your plant in relation to this
machine and the preparations you need to make before the machine is delivered.
4.1 Safety-related aspects to consider when configuring the plant
A number of residual risks are associated with the machine. These are described in the chapter
titled "Safety information" (Page 15) and in related sections.
Take appropriate safety precautions (covers, barriers, markings, etc.) to ensure the machine
is operated safely within your plant.
Observing the operating mode
Observe the machine's operating mode. Use a suitable control system to prevent overspeeds,
thus protecting the machine from damage.
4.2 Ensuring cooling
Ensure that the machine is sufficiently cooled by the cooling air flow at the installation site:
● The cooling air can flow in and out freely.
● Hot discharged air must not be drawn in again.
● If there is no protective canopy, then for vertical types of construction where the air enters
4.3 Thermal motor protection
The machine is equipped with PTC thermistors for direct monitoring of the motor temperature
to protect the machine against overheating during operation. Plan a corresponding circuit for
monitoring.

Operating Instructions 05/2014
The full air flow provided by the fan is only achieved if air can freely enter the impeller. A
clearance of at least 1 times the air intake diameter must therefore be provided in the axial
direction.
from the top, the air entry openings must be protected against the ingress of foreign bodies
and water.
