INSTALLATION
This Surge Protective Device (SPD) is a high performance device, designed to provide protection
for sensitive electronic loads connected to communication loop circuits that have been isolated
from the public switched telephone network 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 and the following instructions. These devices are only to be employed on
communication loop circuits which have been isolated from the Public Switched Telephone Network.
APPLICATION
DTK-MBS, DTK-MB10 base is for installations inside 4”x4” electrical boxes and other locations
where there is a space constraint. This base is available as a 1 up array (standard) or 2 through 5
up array for multiple pair terminations to one point of use. Specify DTK-2MB, 3MB, 4MB or 5MB
for 2 through 5 up arrays.
DTK-MBV base is for retro installations and new installations where conductors need to terminate
horizontally across the base. This base is only available in a 1 up array.
DTK-2MHLP surge module is for hardwired series installations on voltages ranging from 5 - 75 Volt
(DTK-2MHLP models only), 130 Volt (DTK-2MHTP model only) loop circuits or communication
circuits.
INSTRUCTIONS:
Caution: Measure all voltages to insure applied voltage does not exceed the voltage rating of
the unit. Improper installation voids the warranty.
MB/MBS/MBV BASE INSTALLATION
1. Turn off the power at the circuit to be protected before beginning installation.
2. Securely mount the snap track between the field wiring and your equipment to be protected. Use the two
#8 screws provided to fasten the snap track.
3. Connect ground to the ground terminal using a minimum of 14 AWG wire.
4. Connect the supply/field wiring to the UNPROTECTED side of the MB/MBS/MBV base. Connect the 1st pair to
position 1+ and 1- , than the 2nd pair to position 2+ and 2-.
5. Connect the equipment wiring to the PROTECTED side of the MB/MBS/MBV base. Connect the 1st pair to
position 1+ and 1- , than the 2nd pair to position 2+ and 2-.
6. Make sure the UNPROTECTED supply/field wiring and PROTECTED equipment wiring conductors do not
occupy the same space or conduits.
7. Make sure the wire distance from the base to protected equipment is greater than the wire distance from
the base to ground. Plan for about 3’ of conductor length.
MODULE INSTALLATION
Insert the module into the base making sure the polarizing keys in the block are aligned with
the notches cut into the edge card printed circuit board.
8. After all connections have been made and no hazards exist, restore power.
