H6EX-A2 Instructions for Safety
Putting into Service
The H6EX-A2 must be used with a certified Isolation Barrier to supply a n12VDC. The H6EX-A2 has the
following entity parameters:
FIGURE 1:
H6EX-A2 Control Drawing
Notes:
A.
The H6EX-A2 requires two barriers for operation:
1.
A barrier to supply a nominal 12VDC to the unit (pins 1 and 2).
2.
A barrier to protect the two analog outputs (pins 6 and 7).

C.
The H6EX-A2 ground (pin 2) and all attached barrier grounds MUST be connected together so that V
max
never exceeds its
allowed voltage.
D.
I
max
(or I
i
) is the sum current of all attached barriers.
E.
All grounding path connections should be secure, permanent, visible, and accessible. The grounding path resistance
from the farthest barrier to the grounding electrode should not exceed 1 ohm.
F.
The installation must be in accordance with the National Electrical Code, NFPA 70, Articles 504 and 505, Canadian
Electrical Code C22.1 Section 18, and ANSI/ISA-RP12.06.01.
Use
The sensor is designed to measure dual-axis inclination and output an analog signal.
Assembling and Dismantling
The H6EX-A2 shall not be serviced, dismantled, or re-assembled by the user.
