Installing Using A Spigot Gland And Auxiliary Junction Box - Crowcon IRmax Instructions D'installation, D'utilisation Et De Maintenance

d. Secure the two bracket fixings so that the IRmax is held firmly in place. Re-fit the
weatherproof cap.
e. Once the IRmax is securely fixed in place, remove the IRmax rear nut to enable
access to the cable terminals.
f. Prepare the field cable – Crowcon recommends 1.5 mm
(SWA) cable. Other cable types may be used provided they are compatible
with Exd certified glands. Fit a suitably certified Exd cable gland, pass the cable
conductors through the body of the IRmax and screw in the cable gland. Secure
the gland and ensure the cable armour is grounded to the cable gland and the
IRmax body. NB. Don't forget to re-fit the rear nut after installing the cable.
g. The retaining plate (item 9 on Diagram 3, page 5) must be securely fitted
to prevent any risk of the rear nut (or Fixed IR Display or IS Barrier module
accessory) vibrating loose.
