INSTALLATION
This Surge Protective Device (SPD) is a high performance device, designed to provide protection
for sensitive electronic loads connected to service panels, fire panels, or where the SPD is directly
connected to the electronic device. Maximum protection will only be achieved if the SPD is properly
installed. Please read and follow the installation instructions carefully.
NOTICE:
This SPD should be installed and grounded, by a licensed contractor, per the applicable
requirements of the NEC.
When using the
DTK-SLxxxA
version, please take note that this device is an overvoltage and overcurrent
protector and is intended for indoor use on a UL Listed 66 type block which is located on the equipment
side of a UL Listed primary protector.
When using the
DTK-SLxxxB
version, please take note that this device is an overvoltage protector and is
intended for indoor use on low power Communication Loop Circuits which have been isolated from the
Public Switch Telephone Network. The Communication Loop Circuit shall not be exposed to accidental
contact with electrical or power conductors. (National Electric Code, article 800).
Do not use on incoming Telco lines.
APPLICATION
Surge suppression for Voice/Data circuits terminating onto 66 type wire management blocks.
INSTALLATION INSTRUCTIONS:
Caution:
Measure all voltages to insure applied voltage does not exceed the voltage rating of the
module. Improper installation voids the warranty.
SNAP-IT:
1. Install the
SNAP-LITE
surge protector across the punch down clips of the 66 Block using a gentle rolling
action from one side to the other. If you enclonter difficulty in installing the surge protector,
DO-NOT
force
the
SNAP-LITE
. Instead, make sure the clips are not bent or deformed, then try a straight on approach to
align the clips while rolling on the surge protector.
NOTE:
The 66 type block can hole up to 25
SNAP-LITE
devices.
2. The
SNAP-LITE
device is equipped with two test points per circuit for continuity checks with an OHM
meter while the
SNAP-LITE
is installed.
3. Allow for 3’ minimum length wiring from the OUTPUT of the SNAP-IT to the protected equipment.
GROUND BAR:
The
DTK-SIGB
ground bar fits in the ground slot of the
SNAP-LITE
and is designed for an interference fit
and to be held captive by the ground contact. This ground bar has two breakaway tabs that allows a
custom fit when a few
SNAP-LITE’s
are installed on the 66 type block.
1. Break away one or both tabs, depending on the number of
SNAP-LITE’s
are used.
NOTE:
If using 25
SNAP-LITE’s
, do not break off any tabs.
2. Straddle each ground contact slot of each
SNAP-LITE
with the ground bar, then gently squeeze ground
bar into ground slots. Use the Illustrations Page for more details.
GROUND CONNECTION:
3. Connect a minimum #14 AWG wire from the ground connector to the common earth ground.
Always
have one common ground per system to eliminate the possibility of a differential in ground potentials.
Make sure the ground wire is as short as possible.
GROUND RESISTANCE RULE:
Max ground resistance is 25 Ohms, 5 Ohms or less is optimum.
This cannot be an assumed value and must be measured to assure proper grounding.
