Earthing
WARNING: Earthing continuity between the supply cords to and from the
switch must be maintained.
The switch is provided with internal earthing terminals which are suitable for the
connection of the earthing conductors within the flexible supply cords.
Wiring
The switch is provided with a set of terminals which allow the connection of flexible
supply cords.
The supply cords should be of the PCP rubber insulated type (HO5RN-F) which is
suitable for a wet environment. Cable and fuse size must be appropriately selected. For
information on cable fitting consult the wiring diagrams and cable gland & supply cord
fitting instructions.
Ensure the electrical connections are securely made and that the micro switch is
connected in to the live line, not the neutral.
Cable Gland & Supply Cord Fitting Instructions (Single phase supply)
The cable gland assembly Fig. 15 (items 1 & 2) provides the necessary protection
against ingress of solid objects and moisture as well as providing cable retention.
Assembly instructions are as follows: -
1.
Ensure selected cable sheath
diameter is within the permitted range
(6.5 to 9.5 mm).
2. Strip and prepare the cable sheath
and insulators as shown in Fig. 14.
3. Disassemble cable gland as shown in
Fig. 15 and insert cable into position
ensuring ‘O’-ring (item 1) is placed
over the cable before the clamping
insert (item 2) is tightened.
4. Consolidate the stranded conductor
ends by twisting.
5. Insert the phase, neutral and earthing
conductors into the appropriate terminal
block connections (see wiring diagram)
and secure, ensuring all conductor strands
are clamped.
