6. MAINTENANCE
6.1. GENERAL
Read the health and safety warnings in chapter 1.2 Health and Safety Warnings.
) Note: The remote unit does not require preventative maintenance
measures.
Maintenance of the ION-M4/8 19" should be performed by replacing only
components that are contained in this chapter. In order to maintain warranty, take
care not to damage unintentionally the seals on the modules.
) Note: When sending back the unit, use an appropriate packaging, see
chapter 7.2.3 Environmental and Safety Specifications. We
strongly recommend using the original packaging!
) Note: Defect parts should only be replaced by original parts from the
supplier. All interventions inside the housing are at one’s own risk.
) Note: During maintenance ensure the remote unit has been
disconnected from mains.
) Note: Before disconnecting any cables, label any unlabelled cables to
ensure correct re-connection.
) Note: If any system components where changed (DPX/OTRX/PA) a new
“HW discovery” command needs to be carried out and system
gain checked.
For most maintenance procedures appropriate tools are required to ensure correct
handling. All these tools can be ordered from the supplier. For screwing procedures
observe that all our screws have a right-hand thread, i.e. for fastening the screws
turn the tool clockwise and for unscrewing them turn it counter-clockwise.
