Proper Use - Leuze electronic MSI 400 Operating Instructions Manual

2.3

Proper use

The modular MSI 400 safety control may only be operated under the following conditions:
• You are operating the control within the specified operating limits for voltage, temperature, etc. (see the
following for further information: Technical data [chapter 12])
• You are operating the control within the specified areas of application. (Further information: Areas of
application of the device [chapter 2.2])
The control may only be operated by qualified personnel and may only be used on a machine on which it
has been installed and commissioned for the first time by a qualified person in accordance with this
manual.
In the event of any other use or any changes to the device – including within the scope of installation – this
shall nullify any warranty claim with respect to Leuze electronic GmbH.
• The external power supply of the devices must able to bridge a short-term power outage of 20 ms in
accordance with EN 60204. Suitable PELV- and SELV-capable power packs can be obtained as ac-
cessories from Leuze electronic.
• The modules for the MSI 400 system correspond to class A, group 1, in accordance with EN 55011.
Group 1 includes all ISM devices in which intentionally generated and/or wired HF power, which is re-
quired for the internal function of the device itself, occurs.
• If you wish to use the MSI 400 system for domestic purposes, you need to take additional steps to pre-
vent the emission of radio frequency interference in limit class B according to EN 55011. Here are
some steps you might take:
• The use of interference suppressor filters in the supply circuit
• Installation in grounded switch cabinets or boxes
UL/CSA applications:
• Use lines that are suitable for a temperature range of 60 to 75°C.
• Tighten the screw terminals with a torque of 5-7 lbs/in.
• Only use in a pollution degree 2 environment.
• The modules must be supplied by a voltage source with protective isolation, which is protected by a
fuse in accordance with UL 248 with a nominal power of 100 V, wherein V corresponds to the direct
current power supply with a maximum value of 42.4 V DC, which means that the requirements of
UL 508 for the current and voltage limits are met.
• The maximum permissible total current for the MSI-EM-IO84 modules with outputs Q1 to Q4 is I
3.2 A.
