14.3.4.1 Removal and refitting of front input and output panel
In order to connect the cables to the terminals of the input output circuit board, the pump
module cover must be removed and re-installed after wiring. Follow the procedure below.
1.
Isolate the pump from its power supply.
2. Remove the six M3 x 10 Pozidrive screws from the module cover.
3. Remove the module cover from drive. Do not prise off with tools. Make sure gasket is
retained within recessed channel of module cover.
4. Make sure that pre-fitted cable glands are properly seated, secure and have protective
dust caps fitted.
5. Check that the gland nut is free to move. Use a 24 mm spanner if required and remove
the protective dust caps.
6. Loosen, but do not remove the gland cap. Then insert control cable into loosened gland.
7.
Pull through sufficient cable to reach the connectors required, leaving a little slack.
8.
Strip the outer sheath as necessary.
9. Remove 5 mm of insulation from conductors. No tinning/ferrule required.
10. Insert bare cable end into the correct terminal.
11.
Tighten down screw to clamp wire.
12.
Prepare the cable screen(s) by twisting a suitable length. The twisted length(s) shall
ideally be sleeved to prevent shorting.
13. Secure the end of the cable screen to the connector provided.
14. When all conductors are in position, tighten gland caps.
15. Check gasket and replace if damaged. Gasket ensures IP66 (NEMA 4X) protection.
