Example of the CSA certification product label:
To comply with CSA certification for use in hazardous locations, the following information becomes a part of the product literature for
this CSA-certified industrial control product.
• This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D, or non-hazardous locations only.
• The products having the appropriate CSA markings (that is, Class I, Division 2, Groups A, B, C, D) are certified for use in other
equipment where the suitability of combination (that is, application or use) is determined by the CSA or the local inspection office
having jurisdiction.
Important: Due to the modular nature of a programmable control system, the product with the highest temperature rating determines
the overall temperature code rating of a programmable control system in a Class I, Division 2, location. The temperature code rating is
marked on the product label as shown.
Temperature code rating:
The following warnings apply to products having CSA certification for use in hazardous locations.
ATTENTION: Explosion hazard -
• Substitution of components may impair suitability for Class I, Division 2.
• Do not replace components unless power has been switched off or the area is known to be non-hazardous.
• Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
• Do not disconnect connectors unless power has been switched off or the area is known to be non-hazardous.
Secure any user-supplied connectors that mate to external circuits on this equipment by using screws, sliding
latches, threaded connectors, or other means such that any connection can withstand a 15 Newton (3.4 lb.)
separating force applied for a minimum of one minute.

4 ControlNet Coax Tap
Select Where to Mount Your Tap
Use these guidelines to select where to mount your taps.
• There is no spacing requirement between taps; you can install two
adjacent taps using a barrel connector (1786-BNC).
• Make sure the mounting location is convenient for your cable routing.
• Make sure the mounting location allows your wiring to meet these
requirements:
– In conduit - installation of RG6 Quad Shield type coax cable
conforms to this pull force and bend radius:
– Not in conduit - installation of RG6 Quad Shield type coax cable
conforms to this bend radius:
• Do not mount the tap in a position that routes the dropline cable over any
ac power terminals on nearby modules.
Mount Your Taps
You can mount your ControlNet tap (T-tap or Y-tap):
• to a universal mounting bracket, and then mount the tap and bracket as
an assembly
• through the body holes in the tap using:
– screws and flat washers
– and a tie wrap.
Once you have mounted your taps, you can store or discard any unused
universal mounting brackets.
See page 7 for universal mounting bracket and tap mounting dimensions.
For this coax
cable:
The pull strength
should not exceed:
The bend radius
should exceed:
PVC 42.75kg (95lbs) 76.2mm (3.0 in)
FEP 61.65kg (137lbs) 69.9mm (2.75 in)
For this coax cable: The bend radius
should exceed:
PVC 38.1mm (1.5”)
FEP 35.6mm (1.4”)
Tap drop cable 25.4mm (1.0”)
!
ATTENTION: Do not allow any metal portions of the tap,
such as the universal mounting bracket screws or connectors to
contact any conductive material. This contact could cause noise
on the network.
