125 VDC Operation
Proper fusing techniques are required when operating from 125 VDC. Depending on
your ground reference, the hot lead must be fused. A DC failure can maintain an arc
for much longer time and distance. Typically, the main bus is fused at a higher level
than the branch device, which in this case would be the DL105 unit. This double
fusing technique is required when operating from direct current. The recommended
fuse size for the branch circuit to the DL105 is 0.5A (for example, a Littlefuse 312.500
or equivalent).
12/24 VDC Operation
When operating at these lower dc voltages, wire gauge size is just as important as
proper fusing techniques. Using large conductors minimizes the voltage drop in the
conductor. Each DL105 input power terminal can accommodate one 14 AWG or two
16 AWG wires. Each terminal block junction and/or connection creates a voltage
drop, so try to keep the number of connections to a minimum. In general, when using
12/24 VDC input power, observe the same double fusing techniques that are used
with 125 VDC input power. The recommended fuse size for the branch circuit to the
DL105 is 1A (for example, a Littlefuse 312.001 or equivalent).
The power source must be capable of suppling voltage and current complying with
individual Micro PLC specifications, according to the following specifications:
