Indicators:

(6) Red {L1, L2, L3} and (2) Yellow {GND}, Super Bright LEDs

Equipment needed:

Digital Volt Meter with 600V AC or DC rated input minimum, 10M ohm input impedance and CAT III & IV. A pair of insulated test probes with .080" DIA. points.

Directions:

Before and after each test, determine the volt meter is operating satisfactorily through verification of known AC & DC voltage sources. With the meter

switched to ACV and test leads in ACV meter jacks, a qualified person can insert probe points into any two of the (4) terminal posts {L1, L2, L3, GND}.
1. To validate normal powered conditions, AC voltage is observed for all six (6) post pair combination circuits {L1-L2, L1-L3, L2-L3, L1-GND, L2-GND, L3-GND}.
2. To check for zero electrical energy during shut off, verify sources of feedback or stored energy are first neutralized. With the meter and leads setup for ACV

measurement, verify the (6) post pair combination circuits above are de-energized. Change voltmeter and test leads for DCV measurement. Again verify the (6) post

pair combination circuits are also de-energized for DCV (stored energy).

With power removed, free dust and particles from front label and jack sockets with compressed air. Maintain a clean label by gently wiping with a clean damp cloth

while power is removed. Cleaning while powered is not recommended.

OPERATING INSTRUCTIONS

MAINTENANCE:

BEFORE OPENING A PANEL, TURN POWER OFF! SAFETY PROCEDURES STILL APPLY! Before working on an

electrical conductor, verify zero electrical energy with proper voltage testing instrument and the proper procedure as

per NFPA 70E 120.1(5), 120.2 (F)(2)(f)(1-6), OSHA 1910.333(b)(2)(iv)(B)."

AVANT D'OUVRIR UN PANNEAU ÉLECTRIQUE, COUPER L'ALIMENTATION! LES PROCÉDURES DE SÉCURITÉ S'APPLIQUENT

TOUJOURS! Avant d'effectuer des travaux sur un conducteur électrique, vérifier que le courant est coupé à l'aide d'un instrument de mesure de

tension approprié en suivant la procédure adéquate, selon les normes de la NFPA (National Fire Protection Association) 70E 120.1(5), 120.2

(F)(2)(f)(1-6), de l'OSHA (Occupational Safety and Health Administration) 1910.333(b)(2)(iv)(B).
