Replacing spare parts
11.3.3.1
Replacing electrical connections and cable entries
Procedure
1. Read the operating data and the approval information on the nameplates of your device.
2. Order a suitable electrical connection or cable entry for your device (cable gland, sealing
plug or device plug).
To do this, use the article number "7MF7906-..".
Notes for cable glands and device plugs
● When you order a cable gland or a device plug as spare part, consider the following criteria:
– Thread
– Material
– Approval
– IP degree of protection
– Permissible ambient temperature
● The permissible ambient temperature for devices with dust explosion protection deviates
from the permissible ambient temperature of the cable gland and the device plug.
You should therefore not use any cable glands or device plugs from third-party
manufacturers for devices with dust explosion protection.
