SMA MEDIUM VOLTAGE POWER STATION 500SC-JP - Checking the Latches, Door Stops and Hinges

Position Designation
E Door
F Frame construction
Required maintenance material (not included in the scope of delivery):
☐ A suitable water-free, heat-resistant lubricant
☐ Talcum, petroleum jelly or wax for maintaining the seals
Danger to life due to electric shock or electric arc if live components are touched
If the MVPowerStation and its devices are not correctly disconnected, dangerous voltages may be present in the
components which, if touched, will result in death or serious injury.
• Disconnect the MVPowerStation (see Section7.6, page101).
• After switching off the inverter, wait at least 15minutes before opening it to allow the capacitors to discharge
completely.
• Ensure that the MVPowerStation and its devices are voltage-free.
Procedure:
1. Check whether the seals in the sealing area show any damage.
If seals are damaged, contact us (see Section17 "Contact", page256).
2. Apply talcum, petroleum jelly or wax to seals. This will prevent frost damage.
3. After removing the side panels: check whether the side panel seals display any damage in the sealing area.
If seals are damaged, contact us (see Section17 "Contact", page256).
10.4.4 Checking the Latches, Door Stops and Hinges
Required maintenance material (not included in the scope of delivery):
☐ A suitable, water-free and heat-resistant lubricant, e.g. WD40
☐ Non-greasing antifreeze agent, e.g.PS88
Danger to life due to electric shock or electric arc if live components are touched
If the MVPowerStation and its devices are not correctly disconnected, dangerous voltages may be present in the
components which, if touched, will result in death or serious injury.
• Disconnect the MVPowerStation (see Section7.6, page101).

completely.
• Ensure that the MVPowerStation and its devices are voltage-free.
Procedure:
1. Check whether the doors latch easily. Open and close the doors several times.
If the doors do not latch easily, lubricate all moving parts of the latch.
2. Check whether the stops hold the doors in place.
If the doors cannot be arrested, lubricate the door stops.
