Page 5: Safety Precautions
Safety Precautions 1. Safety Precautions This manual contains information concerning the installation and operation of Tower UPS. Please carefully read this manual prior to installation. The Tower UPS cannot be put into operation until it is commissioned by engineers approved by the manufacturer (or its agent). Not doing so could result in personnel safety risk, equipment malfunction and invalidation of warranty. -
Page 6: Debug & Operate
Safety Precautions result in electric shock. Do not start the system if any damage or abnormal parts founded. Contacting the UPS with wet material or hands may be subject to electric shock. Warning Use proper facilities to handle and install the UPS. Shielding shoes, protective clothes and other protective facilities are necessary to avoid injury. - Page 7 Safety Precautions These precautions should be followed implicitly at all times. Particular attention should be paid to the recommendations concerning local environmental conditions and the provision of protective clothing, first aid and fire-fighting facilities. Ambient temperature is a major factor in determining the battery capacity and life.
