WARNING: AC Power to the surge suppressor, at the surge suppressor, and in the vicinity of the
surge suppressor MUST be disconnected prior to performing the following mechanical and electrical
installation procedure.

WARNING: Wiring conductors utilized to attach Phases L1, L2, L3, the Neutral and Safety Ground from
the AC power source to the APEX Series should be color-coded to conform with appropriate electrical
codes and/or accepted wiring practices. It is very important to make no assumptions that wiring colors on
existing electrical installations correspond to proper phase, neutral, or ground connections.

WARNING: The disconnect utilized in the current path from the electrical distribution and the APEX
Series must be coordinated to operate properly in conjunction with all other disconnects contained within
the same electrical distribution.

WARNING: Proper electrical connections must be accomplished in accordance with applicable
International, National, and/or Local electrical code requirements.

APEX Series Installation

The APEX Series surge suppressor models are designed specically to operate on the following
congurations:

Congurations

120V 1Ø 240V 3Ø Delta

120/240 Split 1Ø 220/380 3Ø Wye

120/208 3Ø Wye 230/400 3Ø Wye

240V 1Ø 240/415 3Ø Wye

Suppression is accomplished in parallel between phase conductors and/or between phase and the
neutral conductors, depending upon the voltage conguration. Once activated, the suppressor remains
operative until excess transient energy is dissipated and instantaneous peak line voltage falls below the
approximate 120% overvoltage threshold. At that time the suppressor automatically deactivates, resets
to a “ready” state, and awaits further transient activity.

Mechanical Installation

Step 1:

Select a location along the electrical distribution system as physically close to critical equipment loads
as practical to install the surge suppressor. The suppressor can be installed at distribution panels, at
equipment AC power inputs, or at the secondary windings of isolation transformers. The suppressor must
be positioned within four (4) feet (122 cm) of the AC power source. It is recommended that the suppressor
be installed within two (2) feet (61 cm) of the AC power source, if possible.

CAUTION: Increasing electrical impedance values to the inputs of any transient suppressor, regardless
of manufacturer, can increase the device’s voltage limiting levels. Suppressors should be installed as
physically close to the protected electrical distribution panel or critical load as possible using the largest
size wiring/conductors as practical.

Step 2:

Verify that the maximum current rating of the electrical service to be protected does not exceed specied
amperage rating of the suppressor model to be installed.
