7.4 Cable Entry
Only appropriate certified explosion
proof cable glands or conduit may be

entries in the actuator are tapped M25
x 1.5p or M40 x 1.5p.
In hazardous locations, only one
appropriate certified Explosion-Proof
thread adaptor per entry may be used.

Remove plastic transit plugs. Make
cable entries appropriate to the cable
type and size.
Ensure that threaded adaptors, cable
glands or conduit are tight and fully
waterproof. Seal unused cable entries
with steel or brass threaded plug.
In hazardous areas an appropriate
certified threaded blanking plug must
be installed at the cable entry without
the use of an interposing thread
adaptor.
7.5 Connecting to Terminals
Field wiring connections are by
wire termination ring/spade tags. If
necessary, suitable insulation must be
applied to bare metal ring/spade tags
in order to ensure adequate separation
between 'hazardous live' and non-
hazardous' live circuits considering,
and in accordance with, national
regulations and statutory provisions.
Tags are secured with the supplied
4 mm (control and indication) and
5 mm (power) pan head screws.
