STV25K Series Surge Protective Device
Installation, Operation and Maintenance Manual
Introduction
The Sola/Hevi-Duty STV25K Series Surge Protective Device is a high quality,
transient diversion system designed to protect sensitive equipment from
damaging transient voltage surges resulting from load switching, lightning
strikes and other sources. The installer should perform the following steps to
assure a quality installation. Please read all instructions before starting the
installation of this product. These instructions do not replace national or local
electrical codes - check applicable codes to ensure compliance.
Installation
!
DANGER
ONLY QUALIFIED PERSONNEL SHOULD INSTALL OR SERVICE THIS
SYSTEM. ELECTRICAL SAFETY PRECAUTIONS MUST BE FOLLOWED
WHEN INSTALLING OR SERVICING THIS EQUIPMENT. TO PREVENT
RISK OF ELECTRICAL SHOCK, TURN OFF AND LOCK OUT ALL POWER
SOURCES TO THE UNIT BEFORE MAKING ELECTRICAL CONNECTIONS
OR SERVICING.
Environment – For use indoors, in an ambient temperature of -40ºC to
+50ºC, with a relative humidity 0% to 95% (noncondensing).
Maximum Current Capability – The total current draw the STV25K Series
may continuously handle is 20 Amps. Overloading the unit can permanently
damage the device.
Recommended Fuse – Bussman type SC- 25 class G, Rated 250 Volt
minimum 25 amperes maximum or equivalent. Nominal Voltage – The
maximum continuous operating voltage (MCOV) for the model STV25K-10S
is 150 volts and the MCOV for the model STV25K-24S is 275 volts. Failure to
use the unit at its rated voltage can permanently damage the unit or provide
inadequate surge protection.
Supplemental Enclosures – The STV25K Series must be installed inside
an enclosure and located to prevent accidental contact with terminals during
maintenance or servicing.
Summary Alarm Contacts – Summary alarm Form C (1 N.O. and 1 .C.)
relay contacts rated 125VAC, 5A max. are provided for remote indication of
protection status. Connections may be made to these terminals on the unit
using 18 AWG conductors. Conductor Size – The terminal block connection
for the STV25K can accept wires ranging from #20 AWG to a maximum of #8
AWG. Recommended minimum conductor size is #12 AWG.
Grounding – Input and output ground terminals must be connected for proper
operation. This grounding is not only required for safety, but also for
equipment performance. Incorrect grounding can reduce or impede the
operation of the unit.
Operation
OPERATION
Wiring Connections – Before making connections to the unit, verify that
the unit model number and nameplate voltage rating are appropriate for
connection to the intended power source. See table for voltage rating
applications with typical power source confi gurations.
Mounting –
1. Tilt unit slightly backwards
2. Place on the DIN Rail
3. Push enclosure downwards
until stopped
4. Push at the lower front edge
to lock
5. Shake the unit slightly to
ensure that the retainer has
locked
Detachment from the DIN Rail:
Press button located at the top (rear) of the enclosure downwards (to unlock)
and remove the unit from the rail.
Applying Power – Apply power to the SPD and assure status indications
are normal. Under normal conditions, the "green" LED is illuminated. If all
connections are made and reliable and proper voltages are supplied to
the unit, contact the Technical Services Group at (800)-377-4384 (Direct:
(847) 268-6000) or via email at tech@sola-hevi-duty.com.
