INM 5500 Rev 1043 1 Modules – pre-installation3 1 1 Switch settings for operating conditionsSome modules have operating conditions, such as Line-Fault Detection (LFD), Phase Reversal,etc., that can be established by the setting of switches on the unit. The subminiature switchesare accessible through an aperture on the side of the module (see Figure 3.2) and can be set inthe required positions with, for example, the blade of a small screwdriver.The switch setting options are always indicated on the side label of the module, but the user mayalso consult the individual module information in Section 6 of this manual for details.Figure 3 2: Location of switches3 1 2 Relay outputsReactive loads on all units with relays should be adequately suppressed. To achieve maximumcontact life on all mechanical output relays, the load should not be less than 50mW, e.g. 10mA at ≥5V DC.3 1 3 Ambient temperature considerationsAmbient temperature limits for unenclosed MTL5500 range of isolators are from –20°C to +60°Cwith units close-packed and modules with the -T suffix have an extended temperature rating of+65°C, unless otherwise specified.3 2 Installing columns of isolatorsOn new installations, if isolators are mounted in several rows or columns, mount alternate rows orcolumns so that units face in opposite directions. This allows safe- and hazardous-area wiring loomsto be shared. See Figure 3.1 for isolator dimensions.3 2 1 Mounting isolators on DIN railFigure 3 3: DIN rail mounting and removal of isolatorsClip an isolator onto the DIN rail as shown in Figure 3.3, with the blue signal plugs facingtowards the hazardous-area. To remove an isolator from the rail, insert a screwdriver blade(2.5 - 5.0mm diam.) into the clip as shown. This will release the clip so that the isolator maybe pivoted off the rail - there is no need to lever the clip. Allow a maximum mounting pitch of16.2mm for each unit.OFF positionON position1 2 3 4MountingRemoval
