es filling-level limit switch. The oil level monitoring system has been designed to check the oil level when the gear unit is at standstill before it starts. Information Connect the signal so that the drive motor cannot start when the "oil level too low" signal is active and so that an alarm is output. Bypass this signal in operation. 6.1.3 Gear unit with heating 6.1 Measures prior to commissioning Please observe the following measures to commission the gear unit with heating: Ensure that the heating elements are not exposed. Check the switching points of the temperature monitor. DANGER Explosion and fire hazard Exposed heating elements pose an explosion or fire hazard as they can ignite an explosive atmosphere. Do not switch on the heating elements unless you have checked that they are completely immersed in the oil bath. If heating elements are retrofitted, the maximum heat output ( Page at the outer surface of the heating element must not be exceeded. Commissioning 6.1 Measures prior to commissioning B5-0 en Edition 0/2 6Further information Further information about heating elements can be found in the heating element operating instructions in the complete documentation for the gear unit. 6.1.4 Gear units with oil supply system 6.1 Measures prior to commissioning Implement the following measures before commissioning the gear unit with oil supply sys- tem: Ensure that the maximum permissible pressure in the oil supply system components is not exceeded. Ensure that the maximum permissible temperature of the oil supply system components is not exceeded. Using the oil supply system, lubricate the gear unit for 2 minutes using pre-lubrication phase. During this time, the rolling-contact bearings and gearing are supplied with suffi- cient oil for starting. DANGER Danger of explosion Ignition of potentially explosive atmosphere caused by overheating due to complete loss of or inadequate cooling or lubrication could pose danger to life.
