Connection On Control Section - Eaton PowerXL DC1 20 Series Installation Manual

3.6.2 Connection on control section

The connection to the control section is made using the plug-in connection
terminals:
• Terminals 1, 5, 7, 9: Control voltage output (+24V, +10V, 0V),
• Terminals 2, 3, 4, 6: for digital and analog input signals
• Terminal 8: for a digital or analog output signal
• Terminals 10, 11: for a potential-free relay output

ESD measures
Discharge yourself on a grounded surface before touching the
control terminals and the circuit board to prevent damage
through electrostatic discharge.
NOTICE
Do not connect an external voltage source to control signal
terminal 1 (+24 V)!
DANGER

Before touching or handling the wired control signal terminals,
check to make sure that the terminals (terminals 10 and 11) are
de-energized.
￫
The relay contact (terminals 10, 11) may be wired to a higher-
level control circuit that has a dangerous voltage (e.g., 110 V AC,
230 V AC) even when the variable frequency drive is de-
energized.
￫
When using more than one control voltage, we recommend
using separate cables.
Example
24 V DC at control signal terminals 1, 2, 3, 4, 6, and 8 and
110 or 230 V AC at control signal terminals 10 and 11.
