Installation
2.7.3 Control plug X14
Emergency off
Make sure that pins 47 and 48 are connected via a jumper if you don’t con-
nect an emergency off switch.
A plug for the control plug X14 with a jumper connected between pins 47
and 48 is included in the standard specification.
Description of the Emergency Off connection
Pins 47 and 48 of control plug X14 make it possible to disable the output
stage of the frequency converter via the hardware. The power flow to the
motor is then interrupted.
The two pins must be connected to each other to ensure proper operation.
If the two pins are to be monitored by the system control, a floating (dry)
contact must be available on the system side; load carrying capacity: 42
VDC, 100 mA.
The contact used and the connecting cable must be protected against line
supply voltage through double or reinforced insulation such that no hazar-
dous contact line supply voltage can be applied to pins 47 and 48 in the
event of a fault.
Relay outputs
The MAG.DRIVE
digital
converter has 9 relay outputs. They have changeover
contact. Five relay outputs are permanently assigned a signal.
