2. Check that all connections to the power distribution panel are
correct and properly tightened.
2.10 Input Connections
1. De-energize the DC source.
2. Connect the main Bus A RTN line to the power supply return using
wire and ring connectors rated for up to 100 amps continuous
current. Feed the wire through the supplied rubber insulating boot
and connect the ring terminal to the M8 RTN stud, then securely
fasten with supplied hardware. Slip the insulating boot over the high
current ring terminal and RTN stud on the back panel to help
prevent accidental contact with the stud connection.
3. Connect the Bus A INPUT through a suitably rated disconnect
switch (set in the open position) and a fuse or circuit breaker rated
for 100 amps max continuous operation to the power supply output,
using wire and connectors rated for 100 amps continuous current.
Feed the wire through the supplied rubber insulating boot and
connect the input ring terminal to the M8 Bus A INPUT stud, then
securely fasten with supplied hardware. Slip the boot over the ring
terminal and INPUT stud to help prevent accidental contact with the
stud connection.
4. Repeat input wiring for the Bus B INPUT, its power source and
overcurrent protection device, if the Bus B outputs are to be used.
5. Energize the DC source and close any disconnect switches.
2.11 Software Configuration
Configure the software (see Section 4).
2.12 Energize Loads
Switch on the output breakers 1 to 12 (if installed) to energize any loads
connected to the distribution panel outputs.
2.13 Mixed Polarity or Voltage Installation
All output return (RTN) lines and the main Bus A and Bus B RTN terminals
are common and are referenced to a single internal bus (RTN). Bus A and
Bus B inputs can be wired to a different DC voltage (10- to 60-volt DC) of
either polarity. When used with mixed-polarity voltages, e.g., positive 12
volts on Bus A and negative 48 volts on Bus B, the two voltage sources must
be electrically isolated from each other. Not isolating the two voltage
sources for mixed-polarity applications will short circuit and potentially
damage connected equipment.
