Using a braided wire or another appropriate grounding wire, connect the chassis ground

lug to a building ground.

The earth/ground connection must be verified by an electrical engineer or a service per-

son skilled in electrical installation and grounding.

If the FL SWITCH EP7… is used as cord-connected mains equipment for reliable ground-

ing use it as:

– pluggable equipment type B.

– stationary pluggable equipment type A in a location with equipotential bonding or

with a permanently connected protective earthing conductor.

4.6.5 Alarm relay connections

The relay contact, part of the terminal block connector (see Figure 4-6 and Figure 4-7), is

used to detect user-configured events. The switch provides fail open and fail close con-

tacts (Form C) to form relay circuits based on requirements. If the device is not powered

or if an active alarm is present, the relay de-energizes, initiating the NO and NC states.

The contacts are energized upon power up of the unit and remain energized unless a crit-

ical error occurs. One common application for this output is to raise an alarm if a power

failure or removal of control power occurs.
