INSTALLATION:
Before attempting installation, make sure that the pre-installation requirements of this manual
have been satisfied. If the status of the pre-installation requirements are not known, do not
attempt to continue.
1. MOUNTING
GE TR7000 A-Series Panel Extension SPD units are designed to be installed on GE A-Series
electrical service panels. These instructions shall be considered as the general guidelines to
insure that the SPD is installed safely, while providing the maximum amount of surge
protection available. Before making connections to the unit, verify that the unit model
number, voltage rating and ampere ratings are appropriate for connection to the intended
power source. See page 7 for Voltage Ratings and Power Source Configurations.
Select a breaker location that will allow for a minimum length of wire between the SPD
power terminals and the electrical service panel.
2. POWER CONNECTIONS
Mechanical terminals are provided on the SPD for connection to the electrical power system.
These terminals will accommodate #14 to 2/0 AWG stranded copper conductors. The
minimum recommended wire size for the GE TR7000 SPD is # 6 AWG. See page 10 for
terminal location and identification.
3. WIRE ROUTING
The length of wiring to the SPD must be kept at a minimum for the best performance. Wire
lengths should be short, strait runs between the SPD and power source. Wiring impedance
can be further reduced by twisting the phase, neutral and ground conductors together and
routed in the same raceway or channel. Always avoid sharp bends when routing SPD
connecting conductors.
4. CIRCUIT BREAKER
A dedicated circuit breaker is not required for TPME or TPHE models. However, GE
recommends a 60A rated breaker to serve as a local means of disconnect should the SPD
require servicing or replacement.
5. REMOTE ALARM CONTACTS
Remote Alarm Monitoring Contacts are provided on all SPD model types covered by this
manual. If this type of monitoring is desired, refer to page 10 for the location and wiring
configuration of these contacts. The contacts are dry, 1 form C type, rated 120 VAC, 1 A (30
VDC, 2A) maximum. Once the SPD has been energized and is operating as intended, the
alarm contacts will switch to “Normal Status”. The contacts will only change back to “Alarm
Status” if there is a failure within the SPD suppression circuitry, or if power has been
disconnected from the SPD. Allowing the Remote Alarm Contacts remain unconnected will
not affect the performance or integrity of the SPD.
6. PRE-ENERGIZATION CHECK
Once all of the pre-installation conditions have been met and the GE TR7000 SPD has
been installed, the SPD can now be energized. For SPD Operational Status, refer to
