Warnings:
•
The covers of the housing electronic compartment and the housing itself are
provided with "flameproof" thread. Compared with 'normal' thread the fitting of
"flameproof" thread is relatively tight due to explosion proof requirements.
Therefore screwing on or off of the cover must be done with care, never use
brute force !
•
Keep the threads free of dirt. The thread must be well-greased (with a suitable
teflon grease for example) to make a smooth run possible.
•
For opening of the covers first the "retention" lock must be disabled by means of
a hexagonal socket screwdriver no. 3. After closing of the covers, the "retention
lock" must be enabled again.
•
Before opening of the electronic compartment a delay time after de-energizing
has to be respected:
T6 : at least 35 min., T5: at least 10 min.
The connection compartment with terminal block is schematically depicted in figure 2.
