CONNECTION
4.2.1
Fix panel meter into panel with two clamps (included in delivery).
Connect conductors into screw connectors on the back panel of regulator. Connectors are designed as
separately detachable constructions blocks as follows:
connectors 11 to 18 – process and pulse inputs
connectors 21 to 28 – analogue output
connectors 31 to 38 - communication
connectors 41 to 46 – relay output
connectors 51 to 56 - relay output
connectors 61 to 63 – power supply
Pull each block with connectors out from panel meter (locking force has to be surpassed) in backward di-
rection.Then connect conductors to released blocks with connectors and then insert blocks back to appa-
ratus.
Max. cross section of conductors on relay connectors and power supply is 2,5 mm2, on other connectors
1 mm2.

Instructions for installation into panel and connecting
4.2
Following rules should be observed with designing of the system:
a) All power supply conductors and power lines has to be led separately from signal lines
(e.g. thermocouple, communication). Min. gap between these types of lines shouldn´t be less than 30 cm.
b) If signal line crosses power line they should intersect in right angle.
c) Lead the lines out of the potential source of interference.
d) Don‘t install relay and contactors too close to panel meter.
e) Use twisted and screened conductor for signal line.
