￿Strip the outer sheath as necessary and remove 5mm of insulation from the conductors. No tinning or ferrule is required. Note: If very stiff or large-diame- ter cable is used, it may be convenient to strip the outer sheath before passing the cable’s conductors through the gland. However, to ensure a seal, cable with an undamaged sheath must be present within the gland when it is tightened.

￿Twist a suitable length of the cable screen. Loosen one of the pcb retaining screws and wind the shielding round it. Secure the screen by refastening the screw. Alternatively, secure the cable screen to the adjacent spade connection (where fitted).

￿Push the bared conductor into the square hole in the connector. When the con- ductor is fully in, tighten the retaining screw to hold it in place.

￿When all conductors are in position, use a 21mm spanner to tighten the gland cap to 2.5Nm to ensure a seal. Alternatively, tighten the gland by hand until it is finger-tight and use a spanner to tighten it further by one-half a turn.

Do not strap the control and mains power cables together.

520N watertight module pcb connectors:

Never apply mains power to the terminals within the 520N module. Apply the correct signals to the terminals shown below. Limit signals to the maximum values shown. Do not apply voltage across other terminals.

Permanent damage, not covered by warranty, may result. The maximum rating on the relay contacts of this pump is 30V DC; maximum load 30W.

Note: Also suitable for low power: ie, 1mA at 5VDC minimum.
