Section 8—Adverse Circumstances Power-Style™ QED-2 Switchboards

ENGLISH

Water-Sprayed or Splashed Switchboards (Clean Water Only)

If the switchboard has been sprayed or splashed with small amounts of clean

water, make a thorough inspection of the entire system, and verify that no damage

to conductors or insulation has occurred. Do not open sealed devices such as

molded case circuit breakers or fuses. Replace these devices if they are damaged.

For more information about these devices, refer to the appropriate instruction

manual listed in “Section 11—Reference Publications”.

Inspection and Clean-up of

Clean Water Sprayed or

Splashed Switchboards

Follow steps 1–10 only if:

• No signs of physical damage to the equipment are present.

• The switchboard has not been submerged or exposed to water for long periods

of time.

• The water that has been in contact with the switchboard has not been

contaminated with sewage, chemicals, or other substances that can negatively

affect the integrity of the electrical equipment.

• The water that has been in contact with the switchboard has not entered any

area of the enclosure that may contain wiring installed as intended and located

above any live part. Specifically, inspect for water entering through conduits

located above live parts.

If any one or more of these conditions have not been met, contact

Schneider Electric Services at 1-888-778-2733 (US) or 1-800-565-6699 (Canada).

If ALL of the conditions listed have been met, proceed as follows:

1. Turn off all power supplying this equipment before working on or inside

the equipment.

2. Always use a properly rated voltage sensing device to confirm all power is off.

3. Disconnect and electrically isolate the switchboard so that no contact can be

made with energized parts.

4. Wipe off all moisture from the bus bars, insulators, and insulating material

with a clean, dry, lint-free cloth. Do not use cleaning agents or water

displacement sprays.

5. Prepare the switchboard for insulation resistance (Megger

) testing by

disconnecting all line side supply connections and all load side cable

connections to isolate the switchboard from the wiring system.

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Turn off all power supplying this equipment before working on it.

Failure to follow these instructions will result in death or serious injury.
