Preparing For Use; Safety-Related Aspects To Consider When Configuring The Plant; Observing The Operating Mode; Ensuring Cooling - Siemens SIMOTICS XP 1MB5 Operating Instructions Manual

Preparing 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 explains how you should proceed when engineering a plant or system 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 17) and in related sections.
Take appropriate safety precautions (covers, barriers, markings, etc.) to ensure the machine is
operated safely within your plant.
4.2

Observing the operating mode

Observe the machine's operating mode. Use a suitable control system to prevent overspeeds,
thus protecting the machine from damage.
4.3

Ensuring cooling

Ensure that the machine is sufficiently cooled by the cooling air flow at the installation site:
• Ensure that the cooling air can flow in and out unobstructed. The full air flow provided by the
fan is only possible if air can freely enter the impeller. There must be adequate clearance in
the axial direction. This clearance is specified in the machine dimension drawing
• Make sure that the machine does not draw in the hot discharged air again.
• Ensure that the air intake openings are protected against the ingress of foreign bodies and
water.
4.4

Thermal motor protection (depending on the particular version)

The machine is equipped with temperature sensors to directly monitor the motor temperature
to protect the machine against overload during operation. Plan a corresponding circuit for
monitoring.
