5.1 Installation instructions
5.1.1 Residual current device
• Do not use a conventional RCD as a protective device. Universal current-sensitive
RCDs are permitted as a protective device. During normal operation of MOVIFIT
®
basic units, leakage currents > 3.5 mA can occur.
• SEW-EURODRIVE recommends that you do not use RCDs. However, if a residual
current device is stipulated for direct or indirect protection against contact, observe
the above note.
5.1.2 Line contactor
• Use only a contactor of utilization category AC3 (EN 60947-4-1) as a line contactor.
WARNING
Electric shock due to incorrect RCD type.
Severe or fatal injuries.
• MOVIFIT
®
basic can cause direct current in the protective earth conductor. When
a residual current device (RCD) is used for protection against direct or indirect con-
tact, only install a type B residual current device on the supply system end of the
MOVIFIT
®
basic unit.
NOTICE
Damage due to jogging.
Damage to the MOVIFIT
®
basic unit.
• Do not use the line contactor for jogging, but only for switching the MOVIFIT
®
basic
unit on and off. In jog mode, use the control signals (AS-Interface bits or binary in-
puts).
• Observe a minimum switch-off time of 10 s for the line contactor.
