5.2.2 Output Power Connections
Each system is supplied with compression type terminal blocks for output power connections. These
terminal blocks accept wires in the range of 250MCM to 6AWG. Refer to the applicable standard
for selection of the required wire gauge and type. The output ground wire is to be connected to a
1/4” stud. Please refer to the Figure 4 on the previous page for additional detail.
THE CONVERTER ISOLATES THE OUTPUT POWER FROM THE INPUT POWER AND
EQUIPMENT (SAFETY) GROUNDS SIMILAR TO AN ISOLATION TRANSFORMER.
THE INSTALLER MUST RE-ESTABLISH THE GROUND REFERENCE FOR THE
EQUIPMENT AT TIME OF INSTALLATION. NEUTRAL AND EQUIPMENT (SAFETY)
GROUNDS TO BE CONNECTED PER ABYC STANDARDS.
Single phase configuration systems ignore the Phase C output terminal. Split phase systems use the
Phase A, Neutral, and Phase B terminals. Single phase systems connect between the Phase A and
Phase B terminals.
Replace the power cable access cover and front panel using the removed hardware.
Multi-cabinet systems connect outputs at the switchgear panel. It is recommended that connection
be made to the distribution bus through a manually operated disconnect device such as a molded
case switch or circuit breaker (rated for the total system amperage) for ease and safety of service in
the event of converter failure. The internal power contactors manage power control to the
distribution bus applying power through keypad, Auto-Restart, and remote control based commands.
