This equipment shall be connected in accordance with the manufacturer's installation instructions (drawing GE14581,

figure 31) to intrinsic safety barriers that satisfy the following parameters for each set of terminals.

Main 4-20 mA: Ui = 30 V, Ii = 130 mA, Pi = 1W, Li = 0.55 mH, Ci = 10.5 nF

XMTR circuit: Ui = 28 V, Ii = 100 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF

Limit Switch 1 (LS1): Ui = 16 V, Ii = 76 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF

Limit Switch 2 (LS2): Ui = 16 V, Ii = 76 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF
