ELECTRICAL CONNECTION AND CONTROL PANEL DIMENSIONS
WARNING! Electrical systems must only be set-up, expanded, changed or updated by authorised electricians
or electrical techicians. Ne er work on electrical systems, if you are not qualified to do so.
When working on the electrical system, it must be at zero olts.
SWITC ING OUTPUT
The differential pressure gauge has two adjustable relay outputs in addition to the analogue output signal
at the terminals 5 ... 10 with a maximum switching capability of 250VAC/5A.
FASTENING & TUBE CONNECTION
N.B.: When connecting and routing tubes ensure they are not kinked or damaged.
Leaking tubes and tube connections cause instrument faults or result in
incorrect measurements.
Tube internal diameter = 3.5 / 5.5mm for optimum clamping. Use tube clamps from 25kPa.
P1 = Positi e pressure measurement
P2 = Vacuum measurement
P1 & P2 = Differential pressure measurement
SAFETY & PRODUCT LIABILITY
The product to which this manual refers must only be installed, connected and commissioned by trained specialists.
The rele ant safety conditions, intended use and technical data must be adhered to without fail. According to these conditions,
systems must be switched to a zero- olts condition and be secured to pre ent unintentional switching back on.
Damaged products must not be used. The product must not be used for US FDA controlled application fields.
No liability is accepted for damage arising from improper use.
DISPOSAL
The crossed out garbage can on this product indicates that at the end of its ser ice life, the product must be
disposed of separately from household waste. In future, please take all electrical and electronic products
to a suitably equipped municipal collection point for their reuse / recyling.
