•
PURELAB Prima 20.
•
PURELAB Prima 30/60/90/120.
•
Other products from the PURELAB range meeting

‘Electrical Supply Connection – Section 2a/2b'.
2. LOCATE the level control connection on the micro-
controller board.

PURELAB Prima 20 use 3.5mm jack socket (PCB
identifier J2)
•
PURELAB Prima 30/60/90/120 use 6 pin DIN socket
(PCB identifier JR1)
•
Refer to Technical Support for specific system
guidance.
Note: Only one level control socket must be used to
make a level control connection.
3. DIRECT the level control cable into the electrical
section via the cable tunnels.
4. PLUG the lead into the correct socket as described
