Installation
4.1 Safe Installation Requirements
The product must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards.
The installation of the units must also be in accordance with
the NEC / CEC and any local regulations and should only be
carried out by a competent electrical engineer who has the
necessary training.
4.2 Specific Conditions of Use
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated
cable entry and/or blanking devices during installation. If
conduit is used for installation, seal conduit within 18 inches
from the enclosure.
If entries are fitted with adaptors they must be suitably rated for
the application. Fitting of blanking elements into adaptors is not
permitted.
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer or O-ring must be fitted under any
cable gland or blanking device with metric threads.
Only the explosionproof cover is to be used for access to the
enclosure for installation, service and maintenance.
Connections are to be made into the terminal blocks using
solid or stranded wire, sizes 0.5-2.5mm
2
/ AWG 20-14. Wire
insulation needs to be stripped 6-7mm. Wires may be fitted
securely with crimped ferrules. Terminal screws need to be
tightened down with a tightening torque of 0.4 Nm / 3.5 Lb-in.
Earthing connections should be made to the Internal Earth
terminal in the explosionproof chamber or the external earth
stud.
Check that the ‘O’ ring seal is in place before replacing the
explosionproof cover.
If temperature exceeds 70°C at entry or 80°C at branching
point use suitable rated cable and cable glands
