Cable and Wire Length Guidelines
Table 6 defines cable length guidelines for the various wire sizes for wiring low-voltage (<30 V) input and output
wiring.

UL 916
240 VAC 5A resistive, 1.9 FLA/11/4
LRA, D300 pilot duty, +70°C (158°F),
30K cycles
EN 60730
240 VAC 3A resistive, 3A inductive,
Cos(phi) = 0.6, -20° to 70°C
(-4 to 158°F), 100K cycles
The RELAY output terminals can
accommodate the following maximum
wire sizes:
Two wires per terminal: 1.5 mm
2
(16 AWG) maximum
or
One wire per terminal: 2.5 mm 2
maximum (12 AWG or 2–16 AWG)
Note: You must determine the
required wire size for the high-voltage
(>30 V) terminals according to relay
ratings, the applied load, and the
local, national, or regional electrical
codes.
OCOMn Relay Common
Isolated from all other terminal
commons, including other Relay
Commons.
Note: Reference all relay commons
to the same pole of the supply circuit.
PWM Output OUT5 PWM PWM Output
User selectable PWM output voltage
(5V, 12V default and 15V), 10 mA
continuous current, 100 Hz frequency
See Guideline A in Table 6.
PWM COM PWM Common
PWM return for the single PWM
channel on the controller.
See Guideline A in Table 6.
