Braking Transistor Unit(s) and Remote Mount Resistor Unit(s) Installation
(for GPD506V-A054 and -A068 [CIMR-P5M20111F and 20151F], -B380
[CIMR-P5M41850F] and above, and CIMR-P5M50301F and above).
IMPORTANT
Since the Remote Mount Resistor Unit generates heat during dynamic braking
operation, install it in a location away from other equipment.
Select mounting locations for the Braking Transistor Unit(s) and Remote Mount Resistor
Unit(s) so that wiring between the drive and the (Master) Braking Transistor Unit, and
between each Braking Transistor Unit and its associated Remote Mount Resistor Unit, is
less than 33 feet (10 m).
1. Mount the Braking Transistor Unit(s) on a vertical surface. A Braking Transistor Unit
requires a minimum 1.18 inches (30 mm) clearance on each side and a minimum 3.94
inches (100 mm) clearance top and bottom. Attach the Remote Mount Resistor Unit
maintaining a minimum 1.97 inches (50 mm) clearance on each side and a minimum
7.87 inches (200 mm) clearance on top.
2. In each Braking Transistor Unit, set the nominal line voltage jumper plug to the
correct setting for the installation; this is factory set at the "230V/460V/575V"
position. To access jumper plugs, remove plexiglass cover.
3. If multiple Braking Transistor Units are being installed, the unit closest to the drive
should have the "SLAVE/MASTER" jumper plug on its PCB set to the "MASTER"
position (factory setting); all others must have this jumper plug moved to the
"SLAVE" position.
4. If a single Braking Transistor Unit and Remote Mount Resistor Unit are being installed,
connect them to the drive and external control circuitry according to the chart below
and Figure A6-4.
If two or more Braking Transistor Units and Remote Mount Resistor Units are being
installed, connect them to the drive and to external circuitry according to the chart
below and Figure A6-5.
