Limit Values Of The Anti-Condensation Heating Insulation Resistance; Installation; Machine Installation - Siemens SIMOTICS A 1FU8 Operating Instructions Manual

NOTICE
Damage to insulation
If the critical insulation resistance is reached or undershot, this can damage the insulation
and cause voltage flashovers.
• Contact the Service Center.
• If the measured value is close to the critical value, you must subsequently check the
5.3.3.3

Limit values of the anti-condensation heating insulation resistance

Limit values of the anti-condensation heating insulation resistance
The insulation resistance of the anti-condensation heating with respect to the machine
housing should not be lower than 1 MΩ when measured at 500 V DC.

Machine installation

Note
In order to prevent the eyebolts loosening, after mounting, tighten these or remove them.
NOTICE
Damage to mounted components
Material damage can occur if you use the mounted components to help lift the motor.
Do not use the mounted components to help lift the motor.
● For vertical installation, use all of the eyebolts provided and when necessary, hoisting
straps (DIN EN 1492-1) and/or lashing straps (DIN EN 12195-2) to stabilize the position
of the motor.
● Prevent foreign bodies from falling into the fan cover. For vertical machine installation
with the shaft end facing downwards, attach a protective canopy.
● If the shaft extension is facing upwards, the user must prevent liquid from moving along
the shaft and entering the motor.
● Clean bare metal surfaces with anti-corrosion agent using white spirit to ensure proper
installation and / or machine mounting.
