Edco PC642 Series - Emerson Network Power

Edco PC642 Series
Zone/Loop/Data
The Edco PC642 Series surge protective device, (SPD) is a two-pair (four wire) module
implementing three-stage hybrid technology. This SPD addresses over-voltage
transients with gas tubes and silicon avalanche components. In addition, sneak
and fault currents are mitigated with resettable fuses (PTCs). The PTCs increase
resistance several orders of magnitude when over-currents exceed safe levels. A
normal state resumes when over-currents are removed. The ability to self-restore in
this manner significantly increases suppressor performance and survivability.
The Edco PC642 card edge is gold-plated, double sided and is designed to mate with
the Edco PCB1B-WKEY gold-plated female terminal connector (sold separately).
When snapped together, the data circuits “pass thru” the protector in a serial
fashion from the four “Field Side” terminals to the four “Electronics Side” terminals.
Terminals 1 or 10 of the PCB1B must be attached to Building-Approved Ground.

Ground Terminal 1 or 10 to Building Approved Ground (preferably AC Power safety ground).
DO NOT daisy chain grounds. NOT intended for shield termination. Install ground in accordance
with all applicable codes.
Read and Understand These Instructions
Note:
• These protectors are intended for indoor use on communication loop
circuits which have been isolated from the Public Switch Telephone
Network.
• The communication loop circuits shall not be exposed to accidental
contact with the electric light or power conductors.
• The protectors shall be installed per the applicable requirements of
the National Electric Code, ANSI/NFPA 70.
• Measure DC operating voltage of system to insure it does not exceed
the rating of the selected surge device (5-250 VDC depending on the
device).
Installation:
1. Turn off power to circuit to be protected prior to installation.
2. Screw mounting base #PCB1B-WKEY (ordered separately) in desired
location preferably as close to protected equipment as possible and
in close proximity to a building approved grounding point using (2)
#4 screws. PCB1B may also be DIN rail mounted using optional DIN
clip assembly #11604KIT-PC (ordered separately).
3. Attach field side pairs (26-10 AWG) to positions 3/5 and 7/9, attach
electronics side pairs (26-10 AWG) to positions 2/4 and 6/8. Attach
ground wire (10 AWG) to positions 1 or 10 on base. See Drawing 1.
Torque wires to 44 lbf/in [8 kgf/cm].
4. Insert PC642C module into keyed PCB1B-WKEY base. See Drawing 2.
5. Apply power to protected circuit.
