10.2.3 Transient Protection
Transients must not exceed 2.5kV between any terminal or any terminal and GND. The
electronics provide some protection against transient as per EN61326-1 EMC Immunity.
However, if higher transients are expected, it is recommend that transient protection devices be
included as part of service installation.
10.2.4 Wiring
Confirm service type and check that service markings correspond to expectations. When wiring,
follow the local code regulations. Secure the power input lines together after connection to the
terminal block to prevent an accidental hazardous live condition in the event that a terminal
screw becomes loose. Sleeve or tie wrapping is acceptable. Check to ensure that the power is not
accidentally connected to the low voltage I/O terminal block TB2.
See Chapter 4, Electrical Installation, for power service installation details.
10.2.5 Protective Ground Connection
Connect the protective Earth conductor as instructed in Chapter 4, Electrical
Installation. The Earth Ground connection is located on the inside surface of housing
denoted by the symbol shown left.
