Power supply:
For a model with AC power supply, AC power (165~265VAC) is supplied to the XL-FMUX4E1
through
a becoming standard clover leaf 3-prong receptacle, located on the rear of the unit. The XL-FMUX4E1
should always be grounded through the protective earth lead of the power cable in AC installations.
For a model with DC power supply, DC +24V (18~36VDC) or DC -48V (36~72VDC) is connected
to the detachable terminal block. Please take extra caution to observe the proper polarity of the DC
when wiring the connector. The XL-FMUX4E1 should always be grounded through the protective
earth lead via the frame ground connection for DC installations.
