Start-up
Before start-up: Ensure the prerequisites are fulfilled
▸
Internal mains switch is switched on ( → p. 22, Fig. 4 ).
▸
Enclosures are sealed tight (front doors, cable inlets, enclosure openings).
▸
Permanent protective gas feed is ensured.
▸
Pressurized enclosure system is configured correctly.
Measures during initial start-up
▸
Observe the Operating Instructions of the pressurized enclosure system and make all
necessary settings (parameters
→ p. 35, §6.8 ).
Example:
▸
Set the pre-purge time so that the minimum purge amount is ensured.
Start-up procedure
1 Activate the mains supply:
▸
Either: Switch the mains switch on the Enclosure GMS815P-PS-2G/-3G on ( → p. 22,
Fig. 4 ).
▸
Or: Activate the mains supply at an external source (e.g. main switch).
>>> The pressurized enclosure system now performs an automatic procedure:
a) The Enclosure GMS815P-PS-2G/-3G is purged with protective gas (pre-purge).
b) Then the mains supply of the GMS800 is activated.
2 Wait until the GMS800 is ready for operation ( → “GMS800 Series” Operating Instruc-
tions).
4.2
Shutdown
Shutdown procedure
1 Carry out the preparations for shutdown ( → “GMS800 Series” Operating Instructions).
2 Shut the device together with the pressurized enclosure system down as described in
the Operating Instructions of the pressurized enclosure system.
After shutdown
NOTICE: Risk of damage
The Enclosure GMS815P-PS-2G/-3G has an electronic switch-on current lim-
iter that must cool down after each switch-on.
▸
Wait at least 30 seconds between single switch-on actions.
Otherwise the built-in switch-on current limiter could become defective.
WARNING: Risk of explosions
▸
Do not open the enclosure when an explosive atmosphere is present.
▸
Wait at least 60 minutes after disconnecting from the mains voltage before
opening the enclosure.
▸
Observe the safety information on the enclosure. → p. 11, Fig. 1
