TROUBLESHOOTING
If problems occur during installation, refer to the
following guide. If trouble persists, contact the
local field office.
DANGER
HAZARD OF ELECTRIC SHOCK, BURN, OR
EXPLOSION
•This equipment must be installed and
serviced only by qualified electrical
personnel.
•Troubleshooting may require energizing
auxiliary devices with test power supply.
Make sure that the power supply is OFF
before connecting or disconnecting it to
auxiliary device.
•Do not touch the terminals of the device

Failure to follow these instructions will
result in death or serious injury.
CONDITION POSSIBLE CAUSES SOLUTION
Circuit breaker fails to stay closed. 1. Undervoltage trip not energized.
2. Shunt trip energized.
3. Short circuit or overload on system.
1. Energize undervoltage trip.
2. De-energize shunt trip.
3. Check system for short circuit or overload.
Circuit breaker trips, but no short circuit or overload is
evident. 1. System voltage below undervoltage trip setting. 1. Check system for low voltage.
Push-to-trip button will not trip circuit breaker. 1. Circuit breaker already tripped or in off (O) position. 1. Move circuit breaker handle to reset then to on (I)
position. Press push-to-trip button.

Electrical equipment should be serviced only by qualified personnel. No responsibility is

DANGER
RISQUE D’ÉLECTROCUTION, DE
BRÛLURES OU D’EXPLOSION
• L’installation et l’entretien de cet appareil
ne doivent être effectués que par du
personnel qualifié.
•Coupez toute alimentation de cet
appareil avant d’y travailler.
•Utilisez toujours un dispositif de
détection de tension à valeur nominale
appropriée pour s’assurer que
l’alimentation est coupée.
•Replacez tous les dispositifs, les portes
et les couvercles avant de mettre
l’appareil sous tension.
Si ces précautions ne sont pas
respectées, cela entraînera la mort ou

ATTENTION
RISQUE DE DOMMAGES MATÉRIELS
Les torons du conducteur qui s’engagent
dans la vis de fixation de fil causeront une
indication erronée du couple. Ne laissez
pas les torons du conducteur s’engager
dans les filetages des vis de fixation de fil.
Si ces précautions ne sont pas
respectées, cela peut entraîner des
dommages matériels.
AVERTISSEMENT
RISQUES D’ÉLECTROCUTION OU DE
BRÛLURES
Des courts-circuits ou d’autres dommages
peuvent survenir si le disjoncteur est monté
plus proche du métal du coffret ou des
pièces sous tension qu’indiqué sur le dessin,
de même que si le disjoncteur n’est pas
installé dans un appareil Federal Pioneer
spécifiquement désigné pour lui.
Si ces précautions ne sont pas
respectées, cela peut entraîner la mort ou
des blessures graves.
1. Couper l’alimentation de cet appareil avant d’y travailler. Couper
l’alimentation du disjoncteur.
2. Voir l’étiquette de la plaque avant du disjoncteur ou les directives fournies
avec les cosses optionnelles pour obtenir le calibre des fils et le couple.
