Any dynamic braking must be restrictedto emergency braking and test braking. At static use, there is no brake wear. Therefore thebrake is almost maintenance free." Open the brakes:If exist, Electrical release of the brakes with a supply by accumulators/UPS is possible.Mechanical release of the brakes is possible. Hand release version is available as an option.Retrofitting the hand release is not possible." Dimension the supply and the wiring adequate for the 24 V brake. Brake current about 3,4 A percircuit!" The brake circuits can be opened mechanically. They are separated from each other." The terminal box for the brake may be removed from the motor and mounted on site for a betterattainability." The brake is only allowed to be supplied with power when fastened to the motor and after havingconnected the protective conductor of the motor at the control and the motor side." The brakes have to be protected against over voltage from switching by varistors. The brakes aresupplied with varistors ex factory." The brake release monitoring has to be evaluated; otherwise the type certificate is notfulfilled! The change of state of both brake circuits have to be monitored separately." The brake release monitoring is realized by micro-switches. Please assure with adequate wiring,that the contact-current is at least 10 mA to keep the contacts clean." After a long storage period, the brake rotor may stick to the bearing bracket. Then the motor will notmove even if the brake is released. In this case, please demount the brake from the motor andseparate the brake rotor and the bearing bracket with care.Danger!The levers for hand release must be removed after brake hand release action.Wiring diagram brakeElectrical installation$7%$B*% Part.-No. 01008166-GB (EU-BD 845)10/682ULJLQDORSHUDWLQJLQVWUXFWLRQVZAtop – model series SM160.30B/40B
