Failure to observe this warning results in death or serious injury.
→
Disconnect device from the mains before opening.
→
Wait for 30 seconds after power cut-off prior to opening the housing.
1.
Loosen screws [2] and remove cover [1].
2.
Insert cable glands suitable for connecting cables.
Information: When selecting cable glands observe type of protection (with Ex e
or Ex d approval) and enclosure protection IP (refer to name plate).
The enclosure protection stated on the name plate IP is only ensured if suitable
cable glands are used. Thread types and thread sizes are specified on the
approval plate in explosion-proof version. Refer to chapter <Identification/name
plate>.
