(see Hardware description
assembly (see Dimension drawings
for protection.
2. Mark and drill the required holes to install the control unit (see
page 21). Be careful to control the swarf from the drill.
3. Before you attach the control unit to the cabinet plate, connect the control cables to the
control unit as follows:
•
a) Remove the control unit from the anti-static bag and place it on top, then turn it
over to find the rear connections.
•
b) Identify the correct ends of the control cables (stored in the plastic bag earlier)
to be connected to the control unit.
•
c) Pull the cables through the control unit assembly, so they appear in the opening
at the rear of the control unit. Do not pull the ground connection through, leave it
outside the assembly.
•
d) Check that the cables are not against sharp edges or bare live parts.
Note: Bending radius of the fibre optic cables is at least 3.5 cm (1.38 in.). Do not bend
fibre optic cables during the assembly.
