Installation
11.
Wire and fit the front plate. Ensure the seal is correctly located
and the cables are not trapped or pinched.
When installing connection units using the
front flexible cable clamp
1.
Strip back the outer sheath on the appliance flexible LOAD
cable and trim wires to 55mm in length. Do not trim the
insulation on the three individual cables for the moment.
2.
When using cables of 10mm or more in diameter, it is
necessary to prestress the cable clamp before attempting to
load the cable.
3.
To pre-stress the clamp insert a flat bladed screwdriver into the
cord grip as shown in fig. 6a and flex the clamping jaw open
until it touches the grey base moulding fig. 6b. Then remove
the screwdriver.
IMPORTANT: The clamp must not be re-used for cables below 6mm
diameter after pre-stressing.
4.
Cables below 10mm diameter do not need the cable clamp
pre-stressed and the installation from this point is the same for
all products.
5.
To assist pushing the load cable through the front of the
product, ease the clamping jaw pressure by holding the
product securely in one hand and pushing the tab firmly with
your thumb in the direction shown in fig. 7a.
6.
Continue pushing the cable through the clamp until the outer
sheath reaches the cable stops. See fig. 7b. The jaws must
clamp on the outer sheath.
7.
Carefully strip back the insulation on all three cables to expose
10mm of the conductor.
8.
Ensure all conductors are connected to the appropriate terminals.
NOTE: Terminal screws must be securely tightened. Pull on each cable to
ensure that the terminal screw has securely fixed the conductor.
