X-600M Users Manual Installation and Wiring
2.3 Making Wiring Connections
MIS-WIRING OR MIS-CONFIGURATION COULD CAUSE PERMANENT DAMAGE
TO THE X-600M, THE EQUIPMENT TO WHICH IT IS CONNECTED, OR BOTH.
CAUTION: MAKE SURE POWER IS SHUT OFF BEFORE WIRING!
CAUTION: THIS UNIT SHOULD BE INSTALLED BY A QUALIFIED TECHNICIAN.
2.3.1 Wiring Procedure:
The correct wiring procedure is as follows (a removable terminal connector is provided for making the
power connections):
1. Make sure power is turned off.
2. Remove the terminal connector from the X-600M and make wiring connections to the terminals.
This technique avoids stressing the internal components while torquing the screws.
3. Reconnect the terminal connector.
4. Apply power.
It is recommended that any load (device to be controlled) not be connected to the expansion modules
until after the X-600M has been configured and tested. By doing this, wiring and configuration mistakes
will not cause the load device to turn on unexpectedly.
Make sure the wires are properly inserted into to the terminals and that the screws are tight.
● Use wire rated for 75ºC (min) for connections to the terminal blocks
● See Appendix I for wire size and connector terminal torque specifications
2.3.2 Power Supply Connections
X-600M requires power for its internal logic circuits. Power is provided by connecting a 9 to 28 VDC
power supply to the Vin+ and Vin- terminals. A regulated power supply is recommended, verify that the
power supply is rated for the operating current of the X-600M (See Appendix I: Specifications for
current requirements.) Multiple X-600M units may be connected to a single power supply by connecting
the power supply input terminals in parallel. The power supply must have a high enough current rating to
power all units connected.
The expansion modules draw their power from the X-600M thru the expansion bus ribbon cable. If
expansion modules are connected to the X-600M, the power supply must have enough capacity to
power both the X-600M and any expansion modules connected to the X-600M. The expansion bus can
provide up to 1.70 Amps for powering the attached expansion modules. The maximum number of
expansion modules you can attach depends on the module type and power requirements of the
modules. The expansion modules employ modern switch-mode power supplies. With this type of power
supply the current draw decreases as the voltage increases. As such, you can add more expansion
modules by using a 24-volt power supply than you can with a 12-volt power supply. If additional power is
needed for modules on the expansion bus, please see Section 2.3.4
As an example, an X-11s (2 relay expansion module) would use 105 mA with a 24VDC power supply
