SKF Multilog On-Line System IMx-M
1 - 3
User Manual
All wires and cables connected to input and output terminals shall have a
flammability rating VW-1, FT-1 or fulfill the requirements according to IEC 60332-
1-2 or IEC 60332-2-2.
Because of the redundant power supply, both supply circuits (power connectors
AC1 and AC2) must be disconnected before maintenance. Refer to
section.
Caution to a possible hazard due to mains power double pole/neutral fusing.
An IMx-M rack must be situated in a cabinet with a metal bottom or plastic
bottom with flammability classification of at least V-1. The cabinet must fulfill at
least IP 20.
Each IMx-M rack must be equipped with a forced ventilation which has a feed
of at least 3 x 95 m
3
/h (unrestricted airflow) in order to keep the rack environment
temperature as low as possible, ideally below 30 °C / 86 °F.
IMx-M is designed to operate in an environment of maximum operating
temperature of 65 °C / 149 °F. However, operating IMx-M at this temperature
shall be avoided as it will drastically shorten the lifetime of all components.
PRM with revision number 20 and above has an internal temperature
measurement device/sensor. The internal temperature is monitored and
registered via Event Log. If the rack is operated above 65 °C / 149 °F, the
warranty will be voided.
The recommended fan tray is of at least 3 x 12 cm fan and must be mounted
directly above or below each IMx-M rack (see
installation guidelines).
The cooling fan must be UL or CSA approved and inspected regularly for
optimal performance.
The IMx-M rack is a class A equipment intended for use in an industrial
environment.
The usage of 4-20 mA outputs is only for monitoring purposes. Use relay
outputs for safety alert/danger triggering.
