QUICK START GUIDE
Installation Notes
1.
Follow all Installation Notes. Read before installing, maintaining, or repairing the equipment.
2.
Follow all site specific installation notes and instructions.
3.
Mount to grounded frame using 12-24 screws provided.
Grounding for the equipment is through this connection to the frame. Make sure frame is properly grounded.
4.
Do not install this equipment over combustible surfaces.
5.
Follow NEC, and local and national codes and rules.
6.
Use a personal ESD strap when accessing or removing electronic components.
7.
Use only protectors and holders specified in the equipment Ordering Guide.
8.
Size protectors (fuses or circuit breakers) as required by the National Electric Code (NEC) and/or local codes. Refer to the
equipment ratings to assure current does not exceed:
Continuous Load (List 1) - 64% of protector rating
Maximum Load (List 2 - typically end of discharge) - 80% of protector rating.
9.
Field-wired Conductors - Follow all National Electric Code (NEC) and local rules and regulations when making field
connections.
•
Size field-wired conductors based on listed recommendations, National Electric Code (NEC) and/or local codes based
on 70°C ampacity.
•
Insulation rating: 90°Cminimum; 105°C (minimum) if internal to enclosed equipment cabinets.
10. Bonding Network - Suitable for installation as part of either
•
Common Bonding Network (CBN)
•
Isolated Bonding Network (IBN)
11. Facilities - Suitable for installation in
•
Network Telecommunication Facilities
•
Locations where the NEC applies
12. DC Return - Isolated DC Return (DC-I) or Common DC Return (DC-C)
13. Intra-building ports - Equipment and subassembly ports are suitable for connection to intra-building or unexposed wiring
or cabling. The equipment and subassembly ports can be connected to shielded intra -building cabling grounded at both
ends.
Note: If a panel using the VIM1 meter shows a "Shunt Mis-Wired" alarm message when being used in a +24VDC
system, it will be necessary to swap/reverse the polarity of the monitored shunt pairs(s):
•
For Shunt 1, the shunt pair is S and S/W. Cust this pair in the vicinity of J1 at the VIM1 meter and butt-splice S to S/W and
S/W to S to reverse the input signal polarity.
•
For Shunt 2, the shunt pair is BL and BL/W. Cut this pair in the vicinity of J1 at the VIM1 meter and butt-splice BL to BL/W
and BL/W to BL to reverse the input signal polarity.
