Quick fault finding

• Check if the UPS is connected to an AC input utility supply (municipal AC, Eskom or a generator)

• Make sure all circuit breakers and / or switches which should be on ARE on.  Please take care not to switch on Maintenance Bypass or battery circuit 

• Check the UPS Front Mimic Panel and look for fault indications and/or fault descriptions.  Document these BEFORE calling EDS UPS for assistance.

• If no AC utility power is being fed through to your equipment, and this is required, EITHER switch on the UPS Maintenance (manual) Bypass, or in the case of there being no Maintenance (manual) Bypass, move your equipment to an alternative AC supply.

• The bypass should not be switched on while the inverter is running as this can damage the inverter and drop your load. 

• High DC voltage may be present in your UPS even is the power is switched off.  UNDER NO CIRCUMSTANCES should you try to open the UPS or tamper  with it.  Call EDS UPS if you are in any doubt.

• UPSs contain batteries and therefore should be transported UPRIGHT and with care.
Lying the units down can cause batteries to shift or short – both of which are fire hazards.

• Call EDS UPS Service at (011) 496-1402 for assistance.  Speak to Ian or Anthony.
