4.5.2 Connecting single phase systems
Smartracks (without MCCBs) may be connected to single phase supplies, if
a single phase adapter kit (part number Y2.SR002.0) is used.
The kit comprises two nickel plated copper plates, which replace the existing L1, L2, L3 & N terminals (single phase use only). See diagram.
One plate is fixed across the L1 & L2 studs with the nine equi-spaced holes
to the right; these are connected to the bottoms of the channel circuit
breakers with the standard set of live cables.
The other plate is fixed across studs L3 & N with the three large holes to
the right. These connect to the neutral terminal block (located to the right
of the channel circuit breakers) with the three heavy cables provided in the
adaptor kit.
Having fitted the plates, installation is as for standard Smartracks (see
above).
Y2.SR002.0 contents:
2 x plates
3 x neutral cables (35mm2)
3 x earth cables (16mm2)
4.5.3 Connecting Delta systems
Power wiring is as for standard Smartracks, except that the neutral terminal is unused.
Warning: only Smartracks supplied to operate on delta
power can be connected to delta power supplies.
4.5.4 Cascading a stack of Smartracks
In a stack of two or three Smartracks, it may be preferred to protect the
whole stack from one offboard circuit breaker or switchfuse. In this case,
wire from the switch to the first rack (top or bottom, as convenient), then
make up short power cables to link from the power terminal block in the
first rack to the second, and so on.
