Explosion protection

Handling explosion-proof devices
There are four boreholes for electrical inlets and outlets on the device. The threaded bore
holes can be fitted as required with blind plugs, adapters or cable glands. These screw-
in parts must be suitable for the IIC Zone and have explosion-protection certification.
The enCal 3000 may only be connected using cable glands. These must comply
with local explosion-protection regulations and be installed or replaced by
authorized trained personnel. To comply with explosion-protection regulations,
they must be installed and sealed as specified by the manufacturer of the cable

glands. The relevant regulations must be observed during this process.
The cable inlets must satisfy or exceed the IP rating of the device. NEC-compliant
cable inlet equipment must be used in the USA. CEC-compliant equipment must
be used in Canada.
ATTENTION
Cable glands may only be used with cables which have the following properties:
Not sensitive to cold flow, impermeable to air and at least three metres long
•
(only suitable if cable and cable gland are designed for temperatures of at least
70°C )
(ne convient que si le câble et le presse-étoupe sont conçus pour des
températures de 70°C et plus)
Terminal boxes, cable conduits if they are sealed:
•
-
within 1xD outside the housing for ATEX and IECEx
The regulations in the relevant national and international standards (for example
IEC/EN 60079-14, installation of explosion-protection equipment) must be
followed to the letter.
CAUTION
The installation and connection work must be carried out using the circuit, connection
and pipework plans mentioned in the document. Follow the instructions set out below
carefully and ensure that you have completed all the required safety steps before you
