DTK-DF240S12 (12 Circuit 240VAC 20A Series Surge Protective Device)
CAUTION: Risk of Electric Shock-Only intended for installation in accordance
with National Electric Code, ANSI/NFPA-70, Article 398.
Warning: Turn power off at the main circuit breaker panel before beginning install.
Note: Connect this device in series between the 240VAC power supply and the loads
that require protection. Use 12 AWG Stranded, Cu only conductors with a 3/8” strip
length when terminating the wires at the power lugs. The conductors used to connect
the SPD, to the supply or buss and to ground, shall not be any longer than necessary
and shall avoid unnecessary bends.
1. Remove (4) screws securing the safety barrier, save screws.
2. Remove safety barrier.
3. Connect a Ground (green or bare conductor) from the EARTH terminal at the bottom
of the board to the multi-position grounding buss located at the bottom of the enclosure.
4. Connect the Grounds, (green or bare conductors) from the distribution panel to the
multi-position grounding buss located at the top of the enclosure.
5. Connect the Neutral (white conductor) supply wire from the distribution panel to the
NEUTRAL terminal at the N1 IN lug.
6. Connect the Phase (black conductor) supply wire from the distribution panel to the
Phase terminal at the L1 IN lug.
Note: Circuit 1 must be connected first. The diagnostic circuits get their power from
this input.
7. Connect the Neutral (white conductor) for the connected load to the N1 OUT lug.
8. Connect the Phase (black conductor) for the connected load to the L1 OUT lug.
9. Connect the Grounds, (green or bare conductors) for the connected loads to the
multi-position grounding buss located at the bottom of the enclosure.
10. Repeat the above steps for circuits 2 through 12
Note: Tightening torque for the 240VAC power connections is 20 in-lb.
11. Use 1-1/2” conduit fittings for the AC circuits and a 1/2” conduit fitting for dry contacts.
12. After all connections have been made and no hazards exist, replace safety barrier
and secure with screws.
13. Insert DTK-DF240M surge modules, starting with circuit 1, then restore power.

DTK-DF240M
(Surge Module)
The DTK-DF240S12 is a series connected Surge Protective Device, for 12 individual
loads, with a replaceable surge module for each load. The LED indicators on the top
face of the DTK-DF240M surge module provide power, ground and surge module
health status. When the DTK-DF240M surge module has gone end of life, the large
“REPLACE” RED LED will illuminate and the “GOOD” Green LED will turn off. Also,
the audible alarm will sound to provide an extra alert to indicate the surge module’s
health. To silence the alarm, remove the dead module and replace it with a new,
unused module. If a new module is not available, the alarm can be silenced by
moving the toggle switch into BYPASS mode. When a new DTK-DF240M surge
module is installed, this toggle switch must be moved to the center, or the “NORMAL”
position before installing the new module. The red polarizing keys insure that the
correct voltage module will mate with its corresponding base.
WARNING: When the DTK-240M module has gone end of life, or is missing, the
base is susceptible to damage from surge energy. Make sure you always have a
spare module available. No substitutions shall be permitted.
