Installation and Maintenance - Product E45, 'Cnomo' Series

Electrical Connections

Electrical connections vary depending on the coil type fitted to the valve. The principal alternatives are either Plug and Sock et
or Conduit Entry.
Plug and Socket Coils
Push out connection
block from housing
and insert cable
through gland.
Electrical connections are made to
terminals 1, 2 and earth if necessary.
When a surge suppression diode has
been fitted ensure that terminal 1 is
positive and terminal 2 is negative.

Conduit Entry Coils
(terminal box coils)
Remove cover plate
to allow access to
terminal block and
insert cable through
gland and bush.
Electrical connections are made to the
two terminals and earth if necessary.
When a surge suppression diode has
been fitted the terminals will be polarity
sensitive. Ensure correct connection.

Installation

The valve body is machined with three mounting holes to the dimensions shown below. This enables the user to
mount the valve to a bracket or other suitable location.

Air supply requirements

Filtration & Lubrication
The supply air shall be clean, dry and free from water, moisture, foreign parts and debris. It is recommended that a
<40µ filter/regulator be installed as close to the valve as possible to ensure proper supply air quality. The air supply
can be either lubricated or non-lubricated. In the case of lubricated air being used, the recommended oil types are
ISO and UNI FD22 (Energol HPL ~ Spinesso ~ Mobil DTE ~ Telles Oil).

Connections

Pneumatic Connections

All valve ports are tapped for G1/2 or 1/2"NPT male connectors. The mains air connection is clearly
marked with a number 1. The two outlet ports are marked with numbers 2 and 4, and the two exhaust ports
are marked with numbers 3 and 5. (See pneumatic symbols at top of page.)
Note that if ports are tapped NPT then the body will be stamped with 'NPT' to identify this variation.
