Pentair ERICO CRITEC TSF Series User manual

1. Preparation
Electrical shock or burn hazard.
Installation of this Transient Surge
Filter should only be made by
qualified personnel. Failure to lockout electrical power
during installation or maintenance can result in fatal
electrocution or severe burns. Before making any
connections to the electrical panel, be sure that power
has been removed from all associated wiring, electrical
panels, and other electrical equipment.
The installation of this surge filter should be 1.
installed in accordance with all applicable codes,
such as the National Electrical Code (NEC
®)
, or the
Canadian Electrical Code.
Check to make sure line voltage does not exceed 2.
surge filter voltage requirement. Prior to installation
ensure that the TSF is of the correct voltage,
current, and frequency rating for your application.
The ground / earth terminal must be connected to a 3.
low impedance earth for correct operation.
Do not perform a “Dielectric Withstand” or use a 4.
Mega-Ohm Meter (Megger) to test circuits that are
protected with TSF units. Damage may occur to the
TSF units.
Follow all instructions to ensure correct and safe 5.
operation.
Do not attempt to open or tamper with TSF units in 6.
any way as this may compromise performance and
will void warranty.
2. Introduction
Transient Surge Filters (TSF) are designed for simple
installation onto 35mm DIN rails. They can be selected
for use on distribution systems with nominal RMS
voltages of 120V or 240V at frequencies of 50/60Hz.
The TSF6A24V unit is suitable for 12V and 24Vac/dc
signaling and control systems.
3. Quick Installation Overview
Install in the following manner:
Ensure that power is removed from the area and 1.
the circuits that will be connected.
Snap lock the TSF module to the DIN rail. 2.

terminals.
4. Protection Concepts
The terminals on the TSF units are labeled
“INPUT/LINE” (unprotected side) and “OUTPUT/LOAD”
(protected side) assuming that the source of the
transients is on the input side of the TSF module.
To optimize effectiveness of the TSF protection, the
unprotected and protected wiring should be separated.
Wiring from the exposed transient source to the TSF
should be considered unprotected and kept
approximately 12” (300mm) from all other wiring
wherever possible. Wiring on the equipment side of the
TSF should be considered protected.
The separation of protected and unprotected wiring is
recommended to minimize the risk that transients on
unprotected wiring may cross couple onto protected
circuits and diminish the level of protection available
from the TSF module.

NOTE: The terminals on the TSF units are labeled
Ground / Earth 1,2 (unprotected side) and 7,8
(protected side), Neutral 3,4 (unprotected side) and
9,10 (protected side), and Line 5,6 (unprotected side)
and 11,12 (protected side).
For installations in accordance with the National
Electrical Code (NEC) and UL
®
1449, use the fuse
specified in column A. For installations in accordance
with the International Electrotechnical Commission
(IEC) 60364 and 61643, use the circuit breaker
specified in column B.

5. Mounting
TSF's are designed to clip onto 35mm DIN rails
(standard EN50022). Unless otherwise mechanically
restrained, use horizontal DIN rails with the snap fit
design of the TSF to mount the unit with the label text
in the correct orientation.
NOTE: TSF's must be installed in an enclosure or panel
which:
• prevents the TSF unit ambient temperature from
exceeding 104°F (40°C).
• provides adequate electrical and safety protection
• prevents the ingress of moisture and water
• allows the plug-in module visual indication flag to be
inspected
6. Ground Fault Circuit Interruption (GFCI)
Where GFCI protectors (RCD's/ELCB's) are used, it
is preferable that the TSF modules be installed prior
to these devices (i.e. upstream). If this is not done,
nuisance tripping of the GFCIs may occur during
transient activity.
7. Conductor Termination
Each TSF terminal is designed to accept wire sizes
from 14 AWG to 10 AWG (2.5mm
²
- 6mm
²
) solid or
stranded conductors. The wire insulation should be
stripped back .28-.31 in. (7-8mm) before terminating
into the tunnel terminal.
NOTE:
Do not use greater than 7 in-lb (1.0 Nm) of torque
when tightening the terminals.
8. FUSING AND ISOLATION
Overcurrent protection must be installed in the
upstream circuit of every TSF to provide protection to
the unit itself, the load and the wiring in case of fault
situations. The overcurrent protection device and the
wire size used should be determined according to
table 2.
9. Status Indication
TSF modules have a visual indicator flag on the plug-
in module. Should the plug-in module reach end-of-
life the visual indicator flag provides user-feedback.
Refer to figure 2 for visual flag indicator. The TSF
module should be replaced, as optimum protection is
no longer provided. Refer to Table 1 for replacement
module part number information.
10. Maintenance & Testing
The convenient plug-in module and separate base
design facilitates replacement of a failed plug-in surge
module without needing to undo installation wiring. In
the event you are removing the TSF module, ensure
that the power has been removed from the TSF
module before removing a TSF module from service.
Replacement of a TSF module should only be
undertaken by qualified personnel.
NOTE: TSF units should be inspected periodically, and also
following any periods of lightning or transient voltage
activity. Check the visual indicator flag and replace the
plug-in module if the flag has been activated as in Section 9
Status Indication.
11. Remote Alarm Contact
The TSF has a form C alarm contact for remote
indication of protection status. Refer to figure 3 for
remote alarm plug-in information. The alarm contacts
are rated at 3A @ 125VAC. Use 16 AWG wires to
connect to the M2 contact screws.
