CAUTION
Failure to provide and connect adequate safety and earth grounds at each installation site may result in im-
proper SATS operation or permanent damage to the SATS itself. Grounding facilities and connections must
conform to appropriate national codes and/or local practices.
1. The AC utility conductors installed in the service entrance box must contain a safety ground conduc-
tor. The SATS installer should verify that this grounding conductor is in place, having been installed
along with the AC utility input.
2. A separate enclosure ground wire must be connected between the enclosure ground lug and an
earth ground connection provided by a ground rod installed at the SATS site. In most cases, one
copper or copper-clad steel ground rod of 2.5 meter (8 feet) length driven into the earth will be
sufficient to provide the ground connection required. In some instances, a more elaborate ground-
ing method (such as a ring ground) may be required; however, this may be dictated by state or local
codes and depends on conductivity of the soil within the installation area.
3. The dead metal of the service entrance box
must
be bonded to the metal enclosure that houses the
SATS. Additionally, the ground bar within the service entrance box should be bonded to the metal
enclosures; however, this requirement may be subject to local codes and practices.
4. The grounding wire connected between the SATS enclosure and the earth ground rod should be no
smaller in area than 13 mm² (6 AWG) copper. Both ends of the ground wire should be sealed with an
appropriate anti-oxidation compound.
5. An optional ground bonding connection exists on the 7-position dry contact connector.
Placement in the Enclosure
This SATS has been designed primarily for use within a cabinet or enclosure offering protection from out-
door weather, entry of excessive dust, dirt or moisture, and from unauthorized contact by untrained person-
nel. If used in a controlled environment, the SATS may be located within an indoor equipment cabinet or
may be mounted on a rack shelf. Place the SATS within 36 inches of the line and load terminal block buses
inside the cabinet.
The SATS should be mounted on a ventilated shelf or rack that allows free air circulation, especially through
the right and left side panels of the SATS cabinet. Clearance of at least 1RU or 1.75 inches must be main-
tained around all surfaces of this SATS for unobstructed airflow. Temperature of the air entering the SATS
should not exceed 74°C (165° F). System de-rating will occur at 55°C. See Specifications.
