HTS Transfer Switches –
Equivalent to X-type
HTS switches are used on generators equipped with the PowerManager
®
H-100
Controller.
Power wiring lugs are clearly marked in the transfer switch.
N = Normal Utility Supply
E = Generator Connection Panel
T = Load Distribution Panel
Neutral wires from the utility, the load source and the generator are all connected
to the same lug in the switch.
The control wires consist of RS485 positive
and RS485 negative communication wires
run in a shielded cable. The RS485 wiring
must consist of a 2-wire twisted pair cable
with overall screen.
The shield wire of the RS485 communication cable must only be connected at
the generator. The shield wire should be taped out of the way in the transfer
switch.
When installing an HTS switch, terminals 0 and 183 are not used.
RTS Transfer Switches –
Equivalent to
SR-type
Generators equipped with the R Series
Digital Controller will be matched to an
RTS transfer switch.
The wiring configuration is different from
an HTS switch, but the power lugs use the
same coding.
N = Normal Utility Supply
E = Generator Connection Panel
T = Load Distribution Panel
When installing an RTS switch, terminals 178 and 183 are not used.
