Assembling PN/PN coupler on DIN rail
1.
Assemble the DIN rail such that there is enough space to assemble and heat the
modules (at least 40 mm above and below the modules). If you want to swap the
SIMATIC Micro Memory Card once the PN/PN coupler is assembled, you will have to
leave additional space for this.
2.
Fit the PN/PN coupler in the DIN rail and swing it down.
3.
Wire the PN/PN coupler as described in Chapter Connecting (Page 19).
Note
If the assembly base is a grounded metal plate or a grounded equipment mounting plate,
then you must ensure a low-ohm connection between the DIN rail and base. E.g. with
painted or anodized metals, use a suitable contacting agent or contact washers.

Disassembling the PN/PN coupler
1.
Switch off the PN/PN coupler's power supply.
2.
Loosen the connections and bus connectors on the PN/PN coupler.
3.
Use a screwdriver to push down the slide valve on the underneath of the PN/PN coupler.
4.
With the slide valve still pressed down, swing the PN/PN coupler out of the mounting rail.
