DANGER

HAZARD OF ELECTRIC SHOCK, BURN, OR EXPLOSION.

• Turn off all power supplying this equipment before working on or
inside equipment.

• Please read the following installation and testing warnings.

INSTALLATION

Bonding and Grounding Hazard: During installation into an electrical system, SPD’s must NOT be energized until the
electrical system is completely installed, inspected and tested. All conductors must be connected and functional, including
the neutral (if required). The voltage rating of the device and system must always be verified before energizing the SPD.

Failure to follow these guidelines can lead to abnormally high voltage being applied to the SPD. This may cause the SPD to
prematurely fail or significantly shorten the effective life. The warranty does not cover an incorrectly installed device.

TESTING

High Voltage Testing - DO NOT HI-POT TEST

Any factory or on-site testing that exceeds the normal operating voltage such as high-potential insulation testing, or any
other tests where the suppression components will be subjected to voltages higher than their rated “turn on” voltage must be
run with the suppressor disconnected from the power source. For 4-wire TVSS devices, the neutral connection at the TVSS
must also be disconnected prior to performing high-potential testing and then reconnected upon completion of the test.

Failure to disconnect this surge suppression device and its associated suppression components during elevated voltage testing
will result in damage to the suppression components and/or other electronic components.

Service Clearance

In addition to national and local code requirements, 36 inches of service clearance is needed at the front of the SPD.

Equipment Performance

To obtain the maximum system performance, the unit must be located as close to the circuit to be protected as possible,
minimizing the interconnecting wire length. For every foot of wire length, approximately one (1) nanosecond of turn-on/
turn-off time will be added, and approximately 175 volts (6kV/3kA, 8/20 microsecond) will be added to the clamp voltage.

For optimum transient surge protection, staged surge suppression should be implemented at the service entrance and all
other electrical connections to the building (telephone, CATV, etc.). It should also be implemented at recognized surge
generating loads within the building (arc welding rigs, large motors, switched capacitors, etc.). Additionally, it should be
implemented for sensitive electronic loads (computer equipment, facsimile machines, copy machines, solid state motor
drives, variable frequency drives, etc.). For interconnected electronic loads (via data cabling), surge protective devices should
also be utilized to protect the devices on either end of interconnecting data cables.

APC Manufactures a complete line of surge protection devices for both alternating current (AC) and direct current (DC)
applications. Contact an authorized APC reseller, or order directly from, APC at www.apc.com.

WARNING

!

All electrical connections should be performed by a qualified (licensed) electrician.

All wiring must comply with the National Electric Code (NEC) and applicable local codes.

ELECTRICAL CONNECTIONS
Overcurrent Protection

The Surge Protective Device (SPD) draws very little current under normal conditions and will only conduct for a brief
duration upon encountering a transient surge voltage. APC SPD’s contain UL Listed internal fusing to protect against
abnormal voltage conditions. Note: Fuses are not replaceable.

Voltage Rating

Prior to mounting the SPD, verify that the unit has the correct voltage rating by checking the nameplate voltage or model number.
The service type should match the intended power source. See Table 2 for the voltage rating and service type of the SPD.

Terminals

Terminals have been provided inside the APC modular SPD units for the line (phase), neutral, and equipment safety ground
connections. Terminal wire size for all models is #8 AWG - #1 AWG. Installation torque is 65 inch-pounds.

System Grounding

An equipment grounding conductor must be used on all electrical circuits connected to the SPD. This requirement is
primarily for safety, although SPD performance is enhanced by proper grounding. Proper operation of any surge suppression
system or device depends on a proper grounding system. Incorrect grounding practices will reduce the effectiveness or
interfere with SPD system operation and performance, as well as endanger personnel and equipment. For the best perfor­mance, use a single point ground system where the service entrance grounding electrode system is connected to and bonded
to all other available electrodes, building steel, metal water pipes, driven rods, etc. For sensitive electronics and computer
systems, it is recommended that the ground impedance measurement be 25 ohms or less. When metallic raceway is used as
an additional grounding conductor, an insulated grounding conductor should be run inside the raceway. Adequate electrical
continuity must be maintained at all raceway connections. Do not use isolating bushings to interrupt a metallic raceway run.
A separate isolated ground for the SPD is NOT recommended. Proper equipment connections to grounding system and
ground grid continuity should be verified via inspections and testing on a regular basis as part of a comprehensive electrical
maintenance program.

On 4-Wire Power Systems, neutral to ground bonding should be

installed per the NEC. Failure to do so could cause equipment damage.

Parallel Connection

When making a parallel type of connection (Figure 2), the length of the wiring to the Surge Protective Device (SPD) must be
kept as short as possible to substantially enhance the performance. Long wire runs are to be avoided for the unit to perform
as intended.

To reduce the impedance the wire displays to surge currents, the phase, neutral (if used), and ground conductors are to be
routed within the same conduit and should be tightly bundled or twisted together to optimize the performance of the unit.
Sharp bends in the conductors are to be avoided.
