NOTE:
Use wires of minimum 18AWG, specified to at least 110°C and 300V.
An external switch or circuit breaker (5 Amp) must be installed on the power input
line of PS-220. This switch, located near PS-220, must disconnect both poles of the
supply voltage. It should be rated appropriately and must be marked as the
disconnecting device for PS-220.
BEWARE OF HIGH VOLTAGE 110 or 220VAC INSIDE ENCLOSURE!
2.7 Turn power on. AIR / HIGH OIL light on the PS-220 should be on. If FAIL /
DETECTOR DISCONNECTED light is on, refer to Section 5.

KEEP SENSOR CABLE PROTECTED FROM MECHANICAL DAMAGES! A
DAMAGED CABLE WILL VOID THE IP67 SEALING OF THE SENSOR.
IMPORTANT!
AFTER FINISHING PROCEDURES WITH OPEN ENCLOSURE,
THOROUGHLY CLOSE COVER AND FASTEN SECURELY WITH SCREWS
