This section describes maintenance of the EPS 7000, including safety instructions, preventive maintenance, isolation for maintenance, information about replacement parts, and troubleshooting LCD alarm messages.

3.1Safety Instructions

WARNING:

DC input power to the inverter is normally from a battery

 

bank with a very high short-circuit capacity. Accidental

 

welding and severe burns can be caused by mistakes while

 

connecting or disconnecting these conductors.

ATTENTION

L'entrée DC de l'onduleur est normalement alimentée par une

 

batterie avee un courant de court-circuit élevé. Une erreur

 

lors de la connexion ou deconnexion de ces conducteurs

 

peut causer des soudures accidentelles et des brûlures

 

sérieuses.

WARNUNG!

Gleichstrom zum Wechselrichter kommt gewoehnlich von der

 

Batteriebank mit einer sehr hohen Kurzschluss

 

Leistungsfaehigkeit. Unbeabsichtigtes Schweissen und

 

schwere Verbrennungen koennen die Folgevon fehlerhafter

 

Verbindung und Trennung sein.

 

 

 

 

3.2IMPORTANT SAFETY INSTRUCTIONS FOR SERVICING BATTERIES

A.Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.

B.When replacing batteries, use the same model and manufacturer of batteries.

C.CAUTION — Do not dispose of battery or batteries in a fire. The battery may explode.

D.CAUTION — Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.

E.CAUTION — A battery can present a risk of electrical shock and high short-circuit current. The following precau- tions should be observed when working with batteries:

1.Remove watches, rings, or other metal objects.

2.Use tools with insulated handles.

3.Wear rubber gloves and boots.

4.Do not lay tools or metal parts on top of batteries.

5.Disconnect charging source prior to connecting or disconnecting battery terminals.

6.Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source of ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will be reduced if such grounds are removed during installation and maintenance.
