E2S GNExCP6A-PB Instruction Manual

When wiring to Increased Safety terminal
enclosures, you are only permitted to connect one
wire into each way on the terminal block, unless a
pair of wires are crimped into a suitable ferrule.
Wire sizes allowable are 0.5sqmm to 4.0sqmm
The terminals are only permitted to be wired with
cable in an ambient temperature range of between
-10°C to 80°C. All terminal screws, used or
unused, must be fully tightened down.
Leads connected to the terminals must be
insulated for the appropriate voltage and this
insulation must extend to within 1mm of the metal
of the terminal throat.
8) Testing unit operation
The push button unit can be tested without the
need to replace any element.
To test, lift the cover lift flap to reveal the push
button. The button should be pressed into the body
to activate the unit and place it into the operated
condition.
The call point switch will now change over its
contacts to operate the alarm.
Once testing is complete the unit needs to be reset
from the operated condition.
Rotate the push button anticlockwise by an angle
of 55°, see guide alignment marks on the button
and cover, shown below (1). The push button
should pop back up to its original position.
