PANELBOARD EXTENSION-EGPE100 INSTALLATION INSTRUCTIONS
1. Voltage Verification
Prior to product installation, verify that the voltage rating of the intended electrical service matches the voltage rating of the unit to be installed. Warning: serious injury or damage can result from installing a product with an improper voltage rating. Contact Current Technology if voltage ratings are not identical. For WYE connected systems, verify neutral-ground bond on secondary side of upstream distribution or service entrance transformer. Warranty void if EGPE100 is connected to incorrect voltage configuration or if neutral-ground bond is not present for WYE configured systems.
2. Installation Location
To minimize installed system impedance, install EGPE100 in a location that minimizes electrical wire bends and wiring distance from point of connection. Typically, EGPE100 is installed on top or bottom of panelboard.
Utilizing the hardware supplied with the unit, mount the EGPE100 securely and rigidly to building surface or structural member. Attach conduit and pull wires as necessary.
4. Electrical Connections
VERIFY THAT POWER IS DE-ENERGIZED ON ELECTRICAL LINES ASSOCIATED WITH INSTALLATION OF THIS UNIT.
EGPE100 should be installed in parallel with the electrical distribution system via a three pole 15 Amp breaker or three single pole 15 Amp breakers. For best results, locate these breakers as close as possible to EGPE100. Use #8 AWG copper conductor or larger for all connections including neutral and ground connections. Connect phase, neutral and ground conductors from EGPE100 to the corresponding breakers, neutral bar and ground bar inside the panelboard. Tighten lugs appropriately.
5. Remote Monitor Contacts Option
EGPE100 models are available with two sets of form C remote monitor dry contacts which can be connected to building management systems or remote annunciation alarm panels. To wire contacts, locate the output terminals mounted on the dry contact circuit board. Each set of contacts may be wired independently. Each set of form C contacts include common (C), normally open (NO) and normally closed (NC) contacts. For normally open operation under energized conditions, connect the normally open terminal and common terminal to the monitoring input. For normally closed operation during energized conditions, connect the normally closed terminal and common terminal to the monitoring input. Upon loss of power to any or all phases, contacts will change to alarm state.
6. StatusWatch Option
EGPE100 models are available with StatusWatch diagnostic monitoring. StatusWatch includes battery backed-up audible alarm with test and disable functions, two sets of form C remote monitor dry contacts and optional disturbance counters. Battery is field replaceable, standard 9V alkaline. To activate battery, remove isolation strip between battery and terminal and push battery firmly into battery holder terminals.
To test audible alarm, press alarm test push-button: alarm should sound and alarm/test indicator should flash. Alarm may be silenced by moving toggle switch into upper position; alarm disable indicator will illuminate.
To wire dry contacts, locate two gray terminal blocks on the cabinet door interior. Each set of contacts can be wired independently. For normally open operation under energized conditions, connect the normally open terminal and common terminal to the monitoring input. For normally closed operation during energized conditions, connect the normally closed terminal and common terminal to the monitoring input. Upon loss of power to any or all phases, contacts will change to alarm state.
StatusWatch is available with dual disturbance counter(s) which measure the number of Line-to-Neutral and Line-to-Ground transients occurring in WYE configurations. For DELTA systems, a single counter measures Line-to-Line transients. To reset counters, remove connector on the back of each counter and short pins 1 and 3.
7. Before energizing EGPE100 Check all connections to ensure solid electrical connection. Tighten any loose connections to appropriate torque values.
Measure voltage Line-to-Line, Line-to-Neutral, Line-to-Ground and Neutral-to-Ground to ensure that it does not exceed ±10% of the nominal rated voltage for the unit. Contact factory if these tolerances are exceeded.
8. Final Instructions
If all voltages are in tolerance, replace the cover of the unit and tighten fastening screws. Apply power to the unit by engaging the appropriate circuit breaker(s). Illumination of status lights indicates proper function.
9. DTS-2 Test Point
Disconnect wire harness connector between suppression module and diagnostic monitoring located on interior of EGPE100 cover before testing the unit with the optional DTS-2 Diagnostic Test Set. Reconnect upon completion of testing.
