is turned off and the battery is disconnected.
Emergency stop
Make sure an Emergency Stop disconnecting the power supply, is easily accessible at
any time. The figure below shows how to connect the emergency stop.
Connecting of Supply Voltage
The supply voltage, should be within the operating interval, see Appendix A, on page
23. Connect the supply voltage to +BAT, position 28 and -BAT, position 15. Protect the
module by using a fuse. Requisite fuse level should be 20 A, fast (F).
Connecting the emergency stop and voltage supply.
NOTICE
Do not use the chassis as the negative terminal.
Supplying a high current draw system
If the IQAN-XT2 module is used to control several digital outputs simultaneously, it is
recommended to source power thru the +BAT2 and -BAT2 positions in addition to the
+BAT and -BAT. Requisite fuse level can be max 30 A, fast (F).
