Note
Additional protective ground
If 115 V AC is applied to the relay outputs, the terminal module (-A60) must also be
grounded via a #14 AWG (2.5 mm²) ground conductor.
4.9 Additional connections
Depending on the options installed, further connections have to be established, for example,
dv/dt filter plus Voltage Peak Limiter , connection for external auxiliary equipment, main
circuit-breaker including fuses or circuit-breaker, EMERGENCY OFF button, cabinet
illumination with service socket, anti-condensation heating for cabinet, contactor combination
(EMERGENCY OFF / EMERGENCY STOP), braking unit, PT100 evaluation unit, insulation
monitor, communication modules, encoder evaluator.
Detailed information on connecting individual options with interfaces can be found on the
customer DVD supplied with the device.
