WARNING! The power controller’s protection rating is IP20 with all covers installed and closed. It must be installed in an enclosure that provides all the necessary additional protections appropriate for the environment and application.

WARNING! Ground the power controller via the provided protective earth grounding terminal. Verify ground

is within impedance specications. This should be veried periodically.

WARNING! Electric Shock Hazard: when the power controller has been energized, after shutting off the power, wait at least one minute for internal capacitors to discharge before commencing work that brings you in to contact with power connections or internal components.

WARNING! The installation must be protected by electromagnetic circuit breakers or by fuses. The semicon-

ductor fuses located inside the power controller are classied for UL® as supplementary protection for semicon-

ductor devices. They are not approved for branch circuit protection.

WARNING! When making live voltage or current measurements, use proper personal protective equipment

for the voltages and arc-ash potentials involved.

WARNING! Verify the voltage and current ratings of the power controller are correct for the application.

CAUTION: To avoid compromising the insulation, do not bend wire or other components beyond their bend

radius specications.

CAUTION: Protect the power controller from high temperature, humidity and vibrations.

CAUTION: The power controller warranty is void if the tested and approved fuses are not used.

CAUTION: Only trained and authorized personnel should access and handle the internal electronics and they

must follow proper electro-static prevention procedures.

CAUTION: Install an appropriately sized RC lter across contactor coils, relays and other inductive loads.

NOTE! Provide a local disconnect to isolate the power controller for servicing.

NOTE! The nominal current is specied for ambient temperatures at or below 40° C. Ensure the application

design allows for adequate cooling of each power controller. The power controller must be mounted vertically. The cooling design must prevent air heated by one power controller from causing power controllers mounted above to exceed the ambient operating temperature limit. When power controllers are mounted side by side allow a minimum spacing of 15mm between them.

NOTE! Use only copper cables and wires rated for use at 75°C or greater.

AVERTISSEMENT! Tous les services, y compris l’inspection, l’installation, le câblage, l’entretien, le dépan-

nage, le remplacement de fusibles ou d’autres composants pouvant être réparés par l’utilisateur, doivent être

Installation

WARNING: To avoid damage to property and equipment, injury and loss of life, adhere to applicable electrical codes and standard wiring practices when installing and operating this product. Failure to do so could result in damage, injury and death.

Installing the ASPYRE Power Controller

This chapter provides the information necessary to select and prepare a location and to mount one or more ASPYRE power controllers.

Consider the spacing required for power, load, and control signal wiring before mounting the power controller. Take in to account the controller dimensions, wire bending radius, and cooling requirements. Use good wiring practices to minimize electrical noise problems.

Peripheral Components

Allow room for fuses and fuse holders for the auxiliary input power and fans (if present).

Mounting Orientation

Mount power controllers vertically.

Bend Radius

Allow adequate space to route cables without requiring bending more than permitted for the type of cable.

Environmental Conditions

Mount ASPYRE power controllers in a suitable electrical enclosure. Allow adequate wire bending space and cool-

ing. The maximum ambient temperature in the enclosure must not exceed 104°F (40°C).

Cooling Requirements

To maintain the ambient temperature in the enclosure in which the power controller, circuit breakers, fuses and other components are installed, there must be adequate cooling to remove the heat generated by all the devices. The power controllers are designed to be cooled by drawing cool air in from the bottom and expelling heated air at the top. Typically cabinets are designed with one or more fans on the front door or on the top of the enclosure. The designer will need to know the heat generated by the power controller. See the table below.

Wiring

WARNING: The installation must be protected by electromagnetic circuit breakers or by fuses. The semicon-

ductor fuses located inside the power controller are classied for UL® as supplementary protection for semicon-

ductor devices. They are not approved for branch circuit protection.

Wiring the ASPYRE Power Controller

This chapter describes how to select, prepare and attach power and signal wires to the power controller.

Good Wiring Practices

Follow good wiring practices to minimize the effects of interference from nearby equipment and the line power on the operation of the power controller:

• Install an appropriately sized RC lter across contactor coils, relays and other inductive loads

• Use shielded twisted-pair cables for input, output and communication signals

• Route control and signal cables away from motors and other sources of electromagnetic interference and not parallel to power cables

• Follow all local regulations applicable to electrical installations

NOTE: Use only copper cables and wires rated for use at 75°C or greater.

REMARQUE : N’utiliser que des câbles et des ls en cuivre pour l’utilisation à 75 °C ou plus.
