Input power, cabinet tamper, and UPS fault input wiring
The X300 requires 12-24 V DC power. Connect power
with minimum of 18 AWG wire.
Connect power ground to earth ground in only ONE
LOCATION within the system. Multiple earth ground
connections may cause ground loop problems and is
not advised.
Observe POLARITY on 12-24 V DC input.
Connect the AC FAIL and BATT FAIL inputs to the
corresponding contacts provided on the power supply.
Connect the TAMPER input to a tamper switch on the
enclosure.
TAMPER, AC FAIL, and BATT FAIL connections are
identical to inputs IN 1 to IN 2 and can be configured
as unsupervised or supervised. See step 3. Input
