ELECTRICAL CONNECTIONS
XW60K
is provided with screw terminal blocks to connect cables with a cross section up to 2.5 mm
2
for the RS485 (optional) and the keyboard. To connect the other inputs, power supply and relays,
XW60K
is provided with
Faston connections (6.3mm). Heat-resistant cables should
be used. Before connecting cables make sure the power supply complies with the instrument’s requirements. Separate the probe
cables from the power supply
cables, and from the outputs and the power connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads use a suitable external relay.
NOTE:
the maximum current allowed for all the loads is 16A.
15.1
PROBE CONNECTIONS
The probes shall be mounted with the bulb angled upwards to prevent damage due to casual liquid infiltration. It is recommended to place the return air probe to correctly measure the average room temperature. Place the
defrost termination probe among the evaporator fins in the coldest place, where most ice is formed, far from heaters or from the warmest place during defrost, to prevent premature defrost termination. Place the Discharge
Air Probe on the discharge side of the evaporator.
