CSA Hazardous Location Approval
CSA certifies products for general use as well as for use in hazardous locations.
Actual CSA certification is indicated by the product label as shown below, and not by statements in any user documentation.
Example of the CSA certification product label:
CL I, DIV 2
GP A,B,C,D
TEMP
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.

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:
For this coax cable:
PVC
FEP
The pull strength should not exceed:
42.75kg (95lbs)
61.65kg (137lbs)
The bend radius should exceed:
76.2mm (3.0 in)
69.9mm (2.75 in)
– Not in conduit - installation of RG6 Quad Shield type coax cable conforms to this bend radius:
For this coax cable: The bend radius should exceed:
PVC 38.1mm (1.5”)
FEP
Tap drop cable
35.6mm (1.4”)
25.4mm (1.0”)
•
Do not mount the tap in a position that routes the dropline cable over any ac power terminals on nearby modules.
!
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.
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.
