CKM-CE75-E1M Hardware Information
24-10707-112 Rev. D
2-3
Component Description
AC Input Voltage
Selection (JP1)
Configures the power supply for the AC input voltage.
• For 120 V input, leave jumper intact
• For 230 V input, cut and remove jumper
FAI and Fault LED
Status Indicators
FAI (D22) – Red
Lights when a valid FAI signal is received on the FAI input terminals.
GND FLT (D42) – Yellow
Lights when an impedance is detected between earth ground and
any voltage output or DC common.
AC FLT (D43) – Yellow
Lights when the AC input voltage is low or missing.
SYS FLT (D33) – Yellow
Lights when a system trouble is detected by the power supply.
Trouble conditions indicated by the SYS FLT LED include:
• Missing battery (If BAT DET jumper is ON)
• Earth ground fault (If EARTH GND DET jumper is ON)
• Battery voltage out of range
• DC output voltage out of range
• Ruptured fuse
• Accessory board fault
• Internal fault
AC Input (J9) Connects to provided surge arrestor.
If powering the power supply with a 230 VAC input, cut jumper JP1.
Connect AC power to circuit branch protection of 15 A.
CAUTION: Risk of Damage to the System and
Voided Warranty.
Do not use the power supply with a 230 VAC input
unless the input voltage selection jumper (JP1) is
cut and removed. Failure to cut and remove the
jumper may cause damage to the system and will
void the warranty.
WARNING: Risk of Electric Shock.
Ground the device according to local, national, and
regional regulations. Failure to ground the device
may result in electric shock and severe personal
injury or death.
