2.5 De-energize/Isolation Procedures

DANGER

AC and DC voltages will still be present at the inverter AC and DC landing

points unless utility connection circuit breaker and PV array inputs are

disconnected.

DANGER

Les voltages alternatifs et continus seront toujours présents aux points de

contact CA et CC de l’onduleur à moins que les disjoncteurs du réseau public

et que les alimentations des piles PV ne soient débranchés.

DANGER

Risk of Electrical Shock. Allow ve (5) minutes for internal power to

dissipate prior to entering the enclosure cabinet. Ensure all terminals are

voltage free with the use of a multimeter.

DANGER

Risque d’électrocution. Laissez passer cinq (5) minutes an de permettre

la dissipation du courant interne avant d’ouvrir les panneaux du dispositif.

Utilisez un multimètre sur toutes les bornes an de conrmer l’absence de

courant.

De-energize

The following procedure should be followed to de-energize the inverter for maintenance:

1. Turn the ON/OFF switch on the front display to the OFF position.

2. Position the AC Disconnect lever to the OFF position as shown in Figure 2-1.

3. Position the DC Disconnect lever to the OFF position as shown in Figure 2-1.

4. Open the utility connection circuit breaker (not shown) or overcurrent protection

device (breaker or disconnect).

5. Disconnect the PV using the external PV disconnect (not shown).

6. Install LOTO devices on the equipment as necessary to comply with LOTO require-

ments.
