Invacare® AVIVA® Storm RX 7 Controls System 7.1 Electrical DANGER! Risk of Death or Serious Injury Electric shock can cause death or serious injury. -To avoid electric shock, inspect plug and cord for cuts and/or frayed wires. Replace cut cords or frayed wires immediately. WARNING! Power wheelchairs are equipped with threeprong (grounding) plugs for protection against possible shock hazards. Where a twoprong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to contact a qualified electrician and have the two-prong replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical code. If you must use an extension cord, use only a three-wire extension cord having the same or higher electrical rating as the device being connected. DO NOT, under any circumstances, cut or remove the round grounding prong from any plug used with or for Invacare products. In addition, Invacare has placed RED warning tags on some equipment. DO NOT remove these tags. DANGER! Risk of Death, Injury or Damage Shock hazards and risk of fire exist due to use of improper extension cord and/or use of three prong adapters. -To avoid injury or product damage, when using an extension cord, use only a UL approved three wire extension cord having at least 16 AWG (American Wire Gauge) wire and the same or higher electrical rating as the device being connected. -DO NOT use three prong to two prong adapters. 7.2 Controls Protection System The wheelchair controls system is equipped with an overload protection. If the drive is severely overloaded over a long period of time (for example, when driving up a steep hill) and especially when the ambient temperature is high, the controls system could overheat. In this case, the wheelchair performance is gradually reduced until it stops. The status display shows a corresponding error code (refer to the user manual for your remote). By switching the power supply off and back on again, the error code is cleared and the controls system is switched back on. It can however take up to five minutes until the controls system has cooled down enough for the drive to restore full performance again. If the drive is stalled by an insurmountable obstacle, for example, a curb or similar which is too high, and the driver attempts driving for more than 20 seconds against this obstacle, the controls system automatically switches off to prevent the motors from being damaged. The status display shows a corresponding error code (refer to the user manual of your remote). By switching off and back on again, the error code is cleared and the controls system is switched back on. A defective main fuse may be replaced only after checking the entire controls system. A specialized Invacare provider must perform the replacement. You can find information on the fuse type in 13 Technical Data, page 56. 7.3 Using the Battery Isolation Switch The battery isolation switch must not be used as an ON/OFF button. When the battery isolation switch is used, the LiNX system could lose information like the correct time to display on the remote. There is no need to use the battery isolation switch when transporting the mobility device in a vehicle. The mobility device cannot be charged when the battery isolation switch is switched off. 60127229-A 30
