CAUTION
Utility power lines to GSE SVS-100 must be provided from an appropriately rated utility
distribution panel.
The utility distribution panel must include a "branch" rated circuit breaker (CB). The CB may
also be the "line disconnect" device.
Utility power must be 60Hz, 3 phase, 3 wire plus ground. There must be one wire for each
phase plus one earth ground. See Table 4-1 for information on input current, utility requirement,
and cable sizes. All phase wires must be rated for the full input AC current as listed.

SVS100 Installation, Operation and Maintenance Manual
Prior to connecting the unit to the utility ensure that:
The available grounding connection meets all state and local codes and
the National Electrical Code (NEC).
The main circuit breaker or other "line disconnect" device is within sight of
the unit and is easily accessible to allow complete power down of the unit.
Incorrect power wire installation, or failure to properly ground unit may result
in a severe shock hazard.
Use Copper conductors only.
