If you have the OC32/NG in enclosure, simply mount the OC32/NG using the 4 screws that
come with the unit or enclosure to a suitable flat surface. As with the bare unit, make sure
to allow for enough space to insert the connectors including cables and make sure you can
still access the dipswitches at the side.

OC32/NG Power Supply
The power for the OC32 and the devices controlled by the OC32 can be derived from the
power supply used for your trains (read: the TM44), or you choose one or more separate
power supplies for your OC32(‘s). Which choice you make depends on the optimal Voltage
you need to drive your accessories and the amount of power you need.
If you use multiple power supplies, make sure the negative poles (minus or 0V terminals) of
all the power supplies in your system are connected to each other.
The power supply for your OC32 and connected devices shall always be a positive DC supply!
Most devices that, according to the manufacturer, need AC current, can be fed with DC
current without any problem. Should you have devices that absolutely need AC current, use
a relay to switch them.
The supply for the OC32 is connected to pin 1 (+) and 2 (-) on the 4-pole connector. See
fig 17.

If you want to connect 4 sections per block, at the side you connect to the TM44, bundle all
white wires and put then in the terminal for the A-rail. The individual colours (blue, orange,
green, brown) are used as B0 - B3.
At the track-side, connect the colours blue, orange, green and brown to the B-rail of the
corresponding section. Connect the white wire of the same pair to the opposite side of the
track. In this way you feed the track at multiple locations which helps preventing problems
with bad rail contacts.
If you do not need 4 sections per block, you may use each wire-pair as an individual wire. On
both ends bundle the coloured and white wire of each pair. This way you will effectively have a
cable with 4 conductors with a cross section of 0.4mm
2
each to connect up to 3 sections
per block.
The best way to connect the wire to the track is soldering it to the outer side or bottom of
the rail. Soldering to the bottom is usually only possible when you have not laid your track
yet. The advantage is that it is invisible. The disadvantage is that maintenance can be
problematic. If the wire breaks you won’t be able to reconnect it the way you originally did.
