E-Clips Surge Suppression products for Card Access Systems

120 HWCP 20M: If your power side
of the system requires a hardwire connection, this 120 Volt AC 3-Wire
Single Phase (15-20 Amp) device should be installed as close as
possible to the equipment being protected. This
is an in-line series (AC) surge suppressor and is designed to stop
surges from getting to the PLC – (Mother Board/Computer Board). The 120HWCP20M has a maximum current draw of 15-20 amps and provides both common and normal three-phase noise filtration. UL 1449 listed and rated 400V peak for L-N, L-G, N-G.

3NF: If your power side
of the system is connected by plug-into 110-volt AC, this unit has
three outlets and should be installed in front of the plug-in
transformer.

ILDCP Series Models: These are UL listed 497B in-line series screw terminal multi-stage hybrid devices. These
units are designed to protect the equipment with its close clamping
ability at high-induced voltages. There is a ground lug/wire provided;
only use if you have a common ground i.e. single ground for entire
system to prevent ground loops.

DLT 3S 200 or DLT TOS 200 or DLT 3S200 DSL 200 Volts DC to be used for modems connected to telecommunication line with ring voltage. The DLT 3S/200 has RJ11 connection (jack/plug) and the DLT TOS 200 has screw terminal connection (hardwire). The DLT3S200 DSL has RJ11 connection (jack/plug) for your 56K or DSL line.

D Dual 2W 15V: 15 Volts DC to be used on the Contact/Sensor loops or dedicated (non-ring type) modem lines.

D Dual 4W or D Dual 6W: For the data side specify 6.8 Volts DC, 15 Volts DC, 30 Volts DC depending on your system, 4W for four wire and 6W for six wire. These units are designed to protect the Mother Board/Computer Board, and the Card Reader.

All grounding of low voltage surge suppressors must ground on the shield or the 5th wire used for shield/grounding. The shield/ground must be grounded to the system ground. The system must ground to only one ground source to avoid a ground loop (more than one ground). Normally you will find one ground on the AC power area or main panel ground.
