Pre-Energization Checks
Before you energize the myPV CommsSafe for the first time, let’s verify everything is
ready for initial commissioning.
Skills and Tools Required
Commissioning Staff should be prepared to:
Physically Open the Cabinet
Continuity Test Fuses
Electrically Test Equipment Grounding
Visually Inspect Control Wiring
Physically OPEN control power breakers and fuses
Commissioning Staff should have the following tools:
Insulated flathead Screwdriver 0.6x3.5mm
Ground Resistance Tester
Multimeter w/ resistance (Ω) testing
Control Panel Preparation
Prior to energization, preparation of the Control Panel is intended to prevent damage to
the electrical components due to out-of-range source voltages and also stages the
Control Panel for commissioning steps that will be taken in the next section Initial
Energization.
For the following steps, reference the image
on the next page with
number callouts for
locations of specific items:
1. OPEN (by pulling the top and swinging down) the AC Source Fuse Holder, leave
OPEN
Use a multimeter to verify fuse *continuity
