Chapter 1: Installation and Initial Configuration
Voltage Measurement and Power Wiring
BCM2-96xx series products are available with factory installed line cords
(PLUGGABLE EQUIPMENT) or conduit knockouts and field wiring
terminals (PERMANENTLY CONNECTED EQUIPMENT).
This section describes how to wire models with conduit knockouts and
field wiring terminals. Models with factory installed line cords are not
end user wired and must not be opened or modified.
There are two conduit knockouts on the rear panel – one for voltage
inputs (voltages that are measured), the other for power (power to run
the product). In most cases, only voltage inputs are wired because power
can be derived from the voltage inputs (see jumpers in figure).
Product power is taken from the voltage inputs using two jumpers. A
separate circuit can be used for power which insures BCM2 continues to
operate when voltages inputs fail. A separate power circuit MUST be
used if the voltage inputs exceed power rating (90-240VAC). When using
a separate circuit, remove factory jumpers and wire circuit to the power
L1 and L2 terminals.
Terminals accept 14-18
AWG solid or stranded wire.
Use ring terminals on
stranded wire. Use wire
rated 75°C or higher.
Jumpers power unit from
voltage inputs. Move or
remove as necessary.
Connect ground wires to
stud.
Verify circuit voltages
match product ratings.
