3.0 Electrical Installation
3.1 General Information
The enclosure of the Actuator has two 1/2” NPT cable (or conduit) entry points. Use an appropriate metal conduit
adapter (such as Kopex) for these cable entries and use screened (PVC coated metal) Conduit (connected to earth),
with appropriate ingress ratings. In case only one entry is being used, leave the pre-installed blanking plug (watertight)
for the unused gland hole. Install the conduit as required for the installation and place the wire or cables in the conduit
as described in the wiring instructions.
Remove the terminal enclosure cover from the actuator. A terminal with the following wiring layout (Image 3.1 pictured
below) will be accessible. Note that the terminal block has a “Warning Label” attached covering all terminal connections
except the power supply terminals (not shown). This is to avoid accidental connection of the power supply wires to the
loop input terminals, which will permanently damage the unit. It is important to use a correctly rated 3.5AMP (G12 actuator) or 5AMP
(G13 actuator) power supply.
3.0 Electrical Installation
The wiring of the actuator must be carried out by a qualified technician and according to the
instructions described below.
The wire sizes as recommended in the instructions must be adhered to.
Do not attempt electrical installation unless you are qualified to do so under the laws of your
jurisdiction. It is essential that you understand the information in this section to achieve a
successful electrical installation. If in doubt, contact Armstrong or its authorized representative.
Always consider environmental and mechanical conditions of the installation, such as ambient
temperatures, chemicals, moisture and exposure to mechanical impacts, shock and vibration.
For mechanical protection of the wiring as well as to comply with EMC (Electro Magnetic
Compatibility) standards it is recommended to place the wiring in screened conduit or to use
screened cables.
