Hach-Lange POLYMETRON 9586 - Manual (Page 14)

Alarms and relays
The controller is equipped with four unpowered, single pole relays rated 100-250 VAC, 50/60 Hz,
5 amp resistive maximum. Contacts are rated 250 VAC, 5 amp resistive maximum for the AC
powered controller and 24 VDC, 5A resistive maximum for the DC powered controller. The relays are
not rated for inductive loads.
Wiring relays
W A R N I N G
Potential Electrocution Hazard. Always disconnect power to the instrument when making electrical
connections.
W A R N I N G
Potential fire hazard. The relay contacts are rated 5A and are not fused. External loads connected to
the relays must have current limiting devices provided to limit current to < 5 A.
W A R N I N G
Potential fire hazard. Do not daisy-chain the common relay connections or jumper wire from the mains
power connection inside the instrument.
W A R N I N G
Potential electrocution hazard. In order to maintain the NEMA/IP environmental ratings of the
enclosure, use only conduit fittings and cable glands rated for at least NEMA 4X/IP66 to route cables in
to the instrument.
