Connection terminals
A galvanic separation must fulfill the requirements for reinforced
insulation including creepage distances and clearances specified
in EN 61800-5-1.
13.3 Signal cables
• Use screened cables with a conductor cross-section of min. 28
AWG and maximum 16 AWG for external On/Off switch, digital
input, setpoint and sensor signals.
• Connect the screens of the cables to frame at both ends with
good frame connection. The screens must be as close as
possible to the terminals. See fig.

Stripped cable with screen and wire connection
• Always tighten screws for frame connections whether a cable
is fitted or not.
• Make the wires in the pump terminal box as short as possible.
