5.2.3 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.
5.2.4 Wiring relays
Potential Electrocution Hazard. Always disconnect power to the instrument when making
electrical connections.
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.
Potential fire hazard. Do not daisy-chain the common relay connections or jumper wire
from the mains power connection inside the instrument.
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.
