MAXIMUM CONTINUOUS OPERATING VOLTAGE (MCOV)
In compliance with NEMA LS 1-1992, paragraphs 2.2.7, 2.2.9 and 3.9, Current Technology suppression
filter systems are single pulse surge current tested in all modes at currents up to 150% of the product
design rating by an industry-recognized independent test laboratory. Single pulse surge current
capacities of 200,000 amps or less are established by single-unit testing of all components within each
mode. Due to present industry test equipment limitations, single pulse surge current capacities over
200,000 amps are established via testing of individual components or sub-assemblies within a mode.
All Current Technology suppression filter systems EMI-RFI noise or attenuation rejection values are in
compliance with test and evaluation procedures outlined in NEMA LS 1-1992, paragraphs 2.2.11 and 3.11.
All Current Technology suppression filter systems maximum continuous operating voltages are in com-
pliance with test and evaluation procedures outlined in NEMA LS 1-1992, paragraphs 2.2.6 and 3.6.
Per ANSI/IEEE C62.41-1991 and ANSI/IEEE C62.45-1992, all Current Technology suppression filter sys-
tems are repetitive surge current capacity tested in every mode utilizing a 1.2 X 50 µsec 20KV open
circuit voltage, 8 X 20 µsec 10 KA short circuit current Category C3 bi-wave at one minute intervals
without suffering either performance degradation or more than 10% deviation of clamping voltage at
a specified surge current.

All Current Technology suppression filter systems clamping voltages are in compliance with test and
evaluation procedures established in NEMA LS 1-1992, paragraphs 2.21.0 and 3.10. Values indicate typi-
cal clamping voltage data for models with integral fused disconnect.
1. Voltage/System Verification
Prior to product installation, verify that the voltage rating of
the intended electrical service matches the voltage rating of
the unit to be installed. Verify that ControlGuard™type and
configuration are the same as the motor control center intend-
ed for ControlGuard installation. Warning: serious injury or
damage may result from installing a product with an
improper voltage rating, incorrect type or configuration.
Contact Current Technology if voltage rating, type and configu-
ration are not identical. For WYE connected systems, verify
neutral-ground bond on secondary side of upstream distribu-
tion or service entrance transformer. Warranty void if
ControlGuard is connected to incorrect system configuration
or if neutral-ground bond is not present in WYE configured
systems.
2. Installation Location
Install ControlGuard into motor control center per manufac-
turer’s instructions.
3. Mounting
ControlGuard mounts into a standard NEMA 1 sized motor
control center space. Follow manufacturer’s instructions for
bucket installation. ControlGuard will not feed any loads.
4. Electrical Connections
Before installing ControlGuard, measure voltage Line-to-Line,
Line-to-Neutral, Line-to-Ground and Neutral-to-Ground to
ensure that it does not exceed ±10% of the nominal rated volt-
age for the unit. Contact factory if these tolerances are exceed-
ed. For some applications, a neutral conductor must be tapped
from motor control center neutral bus or neutral conductor
and connected to the neutral lug on the suppression filter sys-
tem depending on motor control center voltage configuration.
Caution: B phase must be the high leg for high leg DELTA
configured products installed on high leg DELTA systems.
Contact factory for other voltage configurations not listed on
ControlGuard technical data sheet.
5. Display Event Counters
ControlGuard comes equipped with dual display event
counter(s) that measure the number of Line-to-Neutral and
Line-to-Ground transients occurring in WYE configurations.
For DELTA systems, a single counter measures Line-to-Line
transients. To reset counters, remove connector on the back of
each counter and short pins 1 and 3.
6. Remote Monitor Contacts Option
ControlGuard models are available with two sets of form “C”
remote monitor dry contacts that may be connected to building
management systems or remote annunciation alarm panels. To
wire contacts, locate the output terminals mounted on the dry
contact circuit board. Each set of contacts may be wired inde-
pendently. Each set of form “C” contacts includes common (C),
normally open (NO) and normally closed (NC) contacts. For
normally open operation under energized conditions, connect
the normally open terminal and common terminal to the moni-
toring input. For normally closed operation during energized
conditions, connect the normally closed terminal and common
terminal to the monitoring input. Upon loss of power to any or
all phases, contacts will change to alarm state.
7. Final Instructions
If all voltages are in tolerance, apply power to ControlGuard by
engaging the fused disconnect switch on front cover of unit.
Illumination of status indicator lights indicates proper function.
8. Diagnostic Testing
In the unlikely event of unit’s overcurrent protection opening,
unit should be tested with a DTS-2 Diagnostic Test Set to verify
operational integrity. To test, locate test point and disconnect
from wiring harness. Follow DTS-2 Diagnostic Test Set instruc-
tions. If the test results are within factory specified tolerances,
replace or reset overcurrent protection. IF TEST RESULTS
ARE NOT WITHIN FACTORY SPECIFIED TOLERANCES,
DO NOT REPLACE OR RESET OVERCURRENT PROTEC-
TION PRIOR TO CONTACTING CURRENT TECHNOLOGY’S
“24X7” TECHNICAL SERVICE HOTLINE AT 1-888-200-
6400. Reconnect test point to wiring harness upon completion
of testing and prior to re-energizing.
