11.4 Pin assignment connector "E" (RS485 -- Modbus)
11.5 Pin assignment Connectors "A – B" (alarm relay)
The alarm outputs are designed as potential-free change-over contacts. Via the potential-free contacts,
the alarm signal can be transmitted, e.g. to a control centre. The connecting plugs of the alarm contacts
are marked with "A" and "B".
DANGER!
Supply voltage!
When wiring the electric connecting lead, it must be ensured that the double or reinforced
insulation between the electric circuits that are dangerous in the case of contact and the
contactable secondary circuit remains maintained.
NOTE!
The additional insulation must be suitable for a test voltage of 1500 V alternating current.
The thickness of the insulation must be at least 0.4 mm.
E.g. flexible insulating tubing, type BIS 85 (Bierther GmbH)
The additional insulation of the connecting leads (mains connection, alarm and indicator relays) can be
implemented as follows:
(1) - Terminals (Connectors "A" and "B")
(2) – Flexible insulating tubing for the connecting leads
(3) – Connecting cable
