PM135 Quick Start Manual
This quick start manual is a short guide on how to mount, connect, configure and operate the
PM135. It is not intended to replace reading the full user manual and particularly the safety
precautions.
Mounting, electrical connection and settings of the PM135 shall be made in
accordance with all applicable laws and/or regulations and be performed by
authorized personnel only.
MOUNTING
Position the PM135 meter in 92×92mm square or 4” round cutout (Figure 1). If two PM135 are
positioned side by side, keep at least 150mm (5.9”) between their centers to allow installation
of add-on modules (140mm/5.5” if only small form modules will be used).
Attach the PM135 unit using washers and nuts. Make sure that the unit is securely attached
into the wall or cabinet fixture.

CONNECTION
To connect follow these steps (Figure 2 shows a 4W LV installation with conventional CTs):
1. Ensure that all incoming power sources are OFF.
2. Check that you have the appropriate power supply.
3. Connect the Power Supply inputs using 1.5 mm²/14AWG dedicated wires and breaker.
4. Connect to the external CTs by passing the external CTs wires through the meter CT cores.
Observe the arrow that indicates the current direction (Figure 2A). For HACS: connect the
red or white wire to the “-” and orange or black wire to the “+“ terminal.
5. In case of a retrofit application where each external CT ends with two wires (Note 2B):
5.1. Pass one wire through the meter CT core.
5.2. Connect the wire to one of the meter “optional CT wire termination”screws.
5.3. Connect the second wire from the external CT to the termination screw.
6. Connect the measured voltage inputs
7. Connect COM1 –RS-485 communication port
8. To connect the optional module:
8.1. Make sure that the power is turned off
8.2. Remove the module cover
8.3. Attach the module and fasten the screws
8.4. Connect the module I/O or communication (see Figure 2C for DI/O wiring)
9. Turn the power up
10. Make sure the diagnostic led is off and solid “123” phase indication is displayed
The “optional CT wire termination”
allows connection of the two wires
from the CTs. They have no internal
connection and their use is optional.

OPERATION
The PM135 is operated using the front panel which consists of an LCD display, 12 LEDs and five
keys as shown below:
Status Line
Date, time, operation mode, current tariff (T1T8), phase indicators and power flow direction.
Operation modes: NORM and TEST. In the TEST mode the energy registers are not
accumulated and the calibration led is 10 times faster (10 pulses per Wh or varh).
Phase indication is on when voltage is ok, blinking when below voltage dip set value or marked
as “-“ when below the interruption set value.
Power flow direction: Normal flow (generation to load) –, reverse flow –or no load –

CONFIGURATION
The essential configuration includes:
1. Basic measurement setup
2. Communication setup and testing
3. Resetting the min/max, energy, demands etc.
Additional recommended configuration: set points, TOU and data logging
Note: It may be easier to configure communication first and use PAS software for setup
