Screwed cable glands are not part of the scope of delivery.The standard motors are manufactured according to efficiency class EFF 2. Energy efficientmotors to efficiency class EFF 1 are available as an option.The motors in the range of 0.12 to 22 kW, are according to the standards to CE, CSA and UL.Country specific executions for USA and Canada are possible on request.2.4.3 The brake motorDesign:Voltage:Type of enclosure:Integrated, DC-excited spring-applied disk brake. Connection via a rectifierinstalled in the terminal box.Connection: 230 or 400 VAC corresponding to 102 or 178 V DC at the brake coil.IP 55 as standard.2.4.4 Operating conditionsPlease consult page 14, chapter 2.5 for hazardous locations according to ATEX.The geared motors are suited for use at ambient temperatures from -10 °C to +40 °C and installation altitudes upto 1.000 m.a.s.l..As delivered with oil filling (see above), ambient temperatures from 0 °C to 40 °C are permitted as standard.In case of deviating ambient temperatures and in aggressive environments (acid vapors or similar), the manufacturermust be consulted first.2.4.5 Outputs, torques and speedsThe outputs and torques listed in the tables refer to a condition at operating temperature with permissible ambienttemperatures and standard lubricants. The specified output speeds are rounded values and refer to the ratedspeed of the motor at delivered rated output.2.4.6 Installation instructionsThe geared motor must be installed free of vibrations. Power transmission elements such as belt pulleys or similarshould be arranged as close to the gear unit housing as possible. The cooling air intake of the motor must not beobstructed by unfavorable installation or contamination. The brake must be accessible for maintenance work.S13
