Floating Output; Junction Box Port; Slave Port - Advanced Energy MDX II User Manual

FLOATING OUTPUT

You can configure the MDXII unit's output such that neither the negative output terminal or
the positive output terminal has a direct connection to ground (floating output). To connect for
floating output, follow these steps:
1. Connect either the positive or the negative terminal of the unit's output connector to the
load.
2. Connect the opposite polarity terminal to ground indirectly through a passive component
or a second power source.
To make these connections, do the following:
a. Strip approximately 1 cm of insulation from the end of the cable to expose the three
wires.
b. Feed one wire into each opening according to the labels on the output connector.
c. Tighten the screws on each compression terminal.
WARNING:
For safety compliance, do not allow the maximum voltage at the MDXII unit's output
connector terminals to exceed ±1600 V with respect to ground when configuring for
floating output. Take into account allowances for ignition voltage (1500 V standard
ignition) when determining safety compliance.

Junction Box Port

This is a 15-pin, male, subminiature-D connector that provides access to a junction box
required for obsolete master/slave configuration.
Note: This port is not currently functional and may or may not be in your unit.

Slave Port

This is a 25-pin, female, subminiature-D connector that provides coordinating information
from the MDXII master unit to the slave unit(s).
Note: This port is not currently functional and may or may not be in your unit.
