6. A good common ground reference (Earth ground) is essential for proper
operation of the DL105. One side of all control and power circuits and the
ground lead on flexible shielded cable must be properly connected to Earth
ground. There are several methods of providing an adequate common
ground reference, including:
a) Installing a ground rod as close to the panel as possible.
b) Connection to incoming power system ground.
7. Evaluate any installations where the ambient temperature may approach
the lower or upper limits of the specifications. If you suspect the ambient
temperature will not be within the operating specification for the DL105
system, measures such as installing a cooling/heating source must be
taken to get the ambient temperature within the range of specifications.
8. The DL105 systems are designed to be powered by 110 VAC , 220 VAC,
125 VDC or 24 VDC normally available throughout an industrial
environment. Isolation transformers and noise suppression devices are
not normally necessary, but may be helpful in eliminating/reducing
suspected power problems.
NOTE:
If you are using other components in your system, make sure you refer to the
appropriate manual to determine how those units can affect mounting dimensions.
Some applications require agency approvals for particular components. The DL105
Micro PLC approval are listed below:
S
UL (Underwriters’ Laboratories, Inc.)
S
CUL (Canadian Underwriters’ Laboratories, Inc.)
The following table lists the environmental specifications that generally apply to
DL105 Micro PLCs. The ranges that vary for the Handheld Programmer are noted at
the bottom of this chart. Certain output circuit types may have derating curves,
depending on the ambient temperature and the number of outputs ON. Please refer
to the appropriate section in this chapter pertaining to your particular DL105.

**Equipment will operate down to 5% relative humidity. However, static electricity problems occur much
more frequently at low humidity levels (below 30%). Make sure you take adequate precautions when
you touch the equipment. Consider using ground straps, anti-static floor coverings, etc. if you use the
equipment in low-humidity environments.
