ALWAYS REMEMBER SAFETY FIRST!

 

WARNINGS & CAUTIONS:

• TO BE INSTALLED BY A LICENSED ELECTRICIAN AND/OR USED IN ACCORDANCE WITH ELECTRICAL CODES AND REGULATIONS.
• INSTALLATION OF ANEMPShield IN A BRANCH CIRCUIT MUST BE DONE BY A QUALIFIED ELECTRICIAN.
• READ ALL INSTRUCTIONS BEFORE INSTALLING.
•EMPShield DEVICES MUST BE INSTALLED ON A LINE THAT IS SERVED BY DISCONNECT MEANS, SUCH AS 20-AMP CIRCUIT BREAKERS OR 20-AMPFUSED DISCONNECT SWITCHES.

• EMPShield MAY NOT SURVIVE SUSTAINED OVERVOLTAGES.
• USE THIS DEVICE ONLY WITH COPPER OR COPPER CLAD WIRE.

FEATURES:

• UL 1449 – Type 2 SURGE SUPPRESSION – Compliant

• (MIL-STD-188-125-1) HIGH-ALTITUDE ELECTROMAGNETIC PULSE PROTECTION – Certified

• IEEE C62.41-1991 category A&B combination wave suppression • Solid-state semiconductor circuitry for each phase
• Each phase independently fused
• Green LED diagnostic indicator for each phase

• NEMA 4 plastic enclosure • 1 conduit entrance port

DESCRIPTION:
EMPShield(120/240V, single -phase version), (120/208V, 3-phase version) or (277/480V, 3-phase version) Branch Panel Mounted devices have been designed to protect residential, small commercial, and industrial establishments from high voltage transients. The standard J-Box plastic enclosure with integrated conduit port simplifies mounting in typical frame construction environments, and provides convenient connection means to existing branch panels.

TO INSTALL:

System Voltage Requirements
1.Measure panel voltage, L-N, to determine the system voltage. System voltage must not exceed the specified maximum continuous RMS voltage on the EMPShield device label.

Location and Mounting
1.Locate the EMPShield device as close as possible to the branch circuit breaker panel. Connection lead length between the EMPShield device and circuit breaker box should be minimal for best protection. The location should also permit good visibility of the EMPShield device’s diagnostic lights.
2. Remove the circuit breaker panel cover and determine the breaker-panel wiring entry point relative to chosen location of the EMPShield device. NOTE: Since the circuit breaker panel and the EMPShield unit have overlapping covers, installation should allow at least one inch of clearance from the edge of the circuit breaker panel cover.
3. For surface-mount circuit breaker panels, the EMPShield device may be connected using rigid conduit to any conduit port.
4. For non-surface mount installations, secure the EMPShield to the support stud in the wall by cutting a 6 x 6-inch mounting hole.

Wiring Connections
The EMPShield (TB – Version) comes with a terminal block 12 AWG COPPER WIRE ONLY. For wire range Solid or Stranded 12 AWG, tighten to Torque 25 in-lbs.
TheEMPShield (W – version) comes with preconnected 12 AWG COPPER WIRE. Tighten to Torque 25 in-lbs.

1. WARNING: TO AVOID FIRE, SHOCK OR DEATH, TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT POWER IS OFF BEFORE WIRING!
2. Connect wire leads to terminal block: BLACK, RED, BLUE to PHASES, WHITE to NEUTRAL and GREEN to GROUND. See Figures 1 through 4 on reverse side.
CAUTION: If plastic conduit is used, Green ground wire must be connected to ground lug, and Green wire inside enclosure must also be connected to ground lug. Failure to do so may result in fire or shock. See Fig. 1, Fig. 2, Fig. 3 and Fig. 4 on reverse side for installation diagrams.
3. Thread the EMPShield device’s wire leads through the conduit to circuit breaker interior.
4. Secure the EMPShield cover with the screws removed previously.
5. Select circuit breakers as close as possible to each service entrance lug. Twenty-Amp (20A) circuit breakers are recommended, and may share EMPShield device and branch circuit leads. The breakers provide additional failure protection as well as a EMPShield connection and servicing disconnect.
NOTE: Do not connect EMPShield leads directly to service entrance lugs. This may result in fire, shock or death.
6. Lead lengths should be as short as possible. Connect the BLACK, RED, BLUE leads to each PHASE through the selected circuit breakers. Connect the WHITE lead to NEUTRAL as close as possible to NEUTRAL entrance service lug.
NOTE: Avoid long loops and do not coil extra lead wire.
7. Replace the circuit breaker panel cover. Installation is complete.

Power ON
1.
Restore power to circuit breaker panel. The green diagnostic lights on the EMPShield should turn ON. These LED lights indicate that the EMP Shield is installed and is monitoring your incoming power source (1 LED for DC versions, 2 LED’s for single phase power, and 3 LEDs for three phase power). 2. If during normal operation a diagnostic light shuts off, have an electrician determine if phase power is applied. If power is present, the unit should be replaced and/or upgraded as soon as possible.
